This study aims to assess the consumption, acquisition and supply of cereals to households in the community of Djougou. A semi-directive survey with KoBoCollect was conducted among 369 households to collect individual cereal food consumption data. The survey data processed by statistical tools showed that the most consumed cereals are maize (95%, p = 0.887), millet (58%, p = 0.755), rice (55%, p = 0.753), sorghum (15%, p = 0.635), wheat (5%, p = 0.920) and fonio barely 5%. The most common mode of acquisition in Djougou is purchase (50%, p = 0.947) but donation is also observed (25%, p = 0.988) as well as production observed in 20.6% of households. Purchases are made from retailers in local markets (45%, p = 0.920) but also in streets and alleys (30%, p = 0.765). The most widely used preservation technique is drying at room temperature (70%, p = 0.995). Households most often dry in the areas provided in the field (50%, p = 0.783) and at home (40%, p = 0.643). The preferred storage location is the kitchen (60%, p = 0.790). The bedroom (20%, 0.669) and the store (15%, 0.522) are the alternative places for storing cereals. In addition, the supply costs of cereals increased between 2020 and 2021. This vertiginous rise in prices is due, among other things, to the covid19 pandemic. The various data generated not only make it possible to have fresh data but also to invest them in the assessment of health risks for the achievement of a high level of protection of the health and life of consumers.展开更多

METHODS: A systematic literature search was conducted using Pub Med and EMBASE. Supplementary literature searches included screening reference lists from relevant studies and reviews. Eligible outcomes were stool wet and dry weight, percentage water in stools, stool frequency and consistency, and total transit time. Weighted regression analyses generated mean change(± SD) in these measures per g/d of dietary fiber. RESULTS: Sixty-five intervention studies among generally healthy populations were identified. A quantitative examination of the effects of non-wheat sources of intact cereal dietary fibers was not possible due to an insufficient number of studies. Weighted regression analyses demonstrated that each extra g/d of wheat fiber increased total stool weight by 3.7 ± 0.09 g/d(P < 0.0001; 95%CI: 3.50-3.84), dry stool weight by 0.75 ± 0.03 g/d(P < 0.0001; 95%CI: 0.69-0.82), and stool frequency by 0.004 ± 0.002 times/d(P = 0.0346; 95%CI: 0.0003-0.0078). Transittime decreased by 0.78 ± 0.13 h per additional g/d(P < 0.0001; 95%CI: 0.53-1.04) of wheat fiber among those with an initial transit time greater than 48 h.CONCLUSION: Wheat dietary fiber, and predominately wheat bran dietary fiber, improves measures of bowel function.展开更多

There are abundant varieties of cereals and oilseeds, however, for a long time, their process suitabilities are still unknown, resulting in the lack of precision processing. This paper summarized the characteristics of cereals and oilseeds, including sensory, physicochemical and processing qualities, their characteristic fingerprinting and products qualities. Furthermore, the quality fast detection method was also analyzed. It also explored the role of mathematical model and the standard evaluation index to determine the process suitability and discussed the opportunity for advanced model capability. We also prospected on scientific problems for expanding the predictive capabilities for processing suitabilities of these abundant varieties, focusing on the better results and advancements towards the processing of cereals and oilseeds products and improvement of their quality.展开更多

Total arsenic concentrations in the samples ranged from 110 ng/gup to 420 ng/g. The i-As in the rice cereals accounted for 33% to 77% of the total arsenic. The observed variability between infant rice cereals makes a dietary survey approach to accessing arsenic exposures difficult.展开更多

Minor cereals are often drought tolerant and fertilizer efficient. In this review we focus the content and bioavailability of phytochemicals in some minor cereals on the basis evidence for increasing plasma phytochemical concentrations and reducing oxidative stress as well as inflammation in humans. Phenolics and Flavanoids are major phytochemicals and may be available with high concentration in minor cereals but as tightly attached with cell wall, their bioavailability is mostly limited. Clinical trials concluded that vitamin E and other common antioxidants were not helpful for managing diabetic complications. Vicious cycles can cause type 1 DM, where as hypoglycemia can forward to down and regulate neuroendocrine. Increased phytochemical bioavailability may be achieved through bio processing of grains but the improvements might be small and have not yet led to changes in clinical associated with reduced risk of T2D. Furthermore, the effects of minor cereals against oxidative stress in healthy individuals can be very low or not occurred but systemic inflammation can be reduced in people after huge intake. More than 300 Indian medicinal plants have antidiabetic property but exact mechanisms for hypoglycemic action of many plants are still unknown. Further studies are required to pay attention toward direct role of minor cereal phytochemicals on alarming diseases diabetes.展开更多

The aim of this study was formulation, preparation and evaluation of low-cost extruded products based on cereals and pulses. Composite flours were prepared using cereals and pulses, then formulated and extruded by a twin screw extruder in Osmania University, Hyderabad, India. Data were analyzed by SPSS software. Results showed: the protein contents of extruded formulas B, D and F were in the highest values. Carbohydrate in the extruded formula A was significantly higher than others. The lowest amount of ash and crude fiber were observed in the formula A. Content of energy in the extruded formulas E, F and C was higher;mean (SD) of Fe content in the extruded formula B, D and F was in the higher ranks among others. Calcium content in the extruded formulas C, E and F was in the highest amounts. Magnesium content in the extruded formulas B, D and F was higher than others. Cu content in the extruded formula C, D, B and F was higher than others. Manganese content in the extruded formulas B, C and F, and zinc content in the formulas B, D and F were higher than others. Tap density showed the lowest amount in the formula B, D and F, while their bulk density was higher. WHC was in the highest amount in the extruded formula A, while WSI in the extruded formula B, D and followed by F was in the highest amount. The mean scores of sensory evaluation of extruded products F showed that this combination has significantly better colour, flavour, texture and overall acceptability than others.展开更多

Nitrogen is among the most yield-limiting factors of cereal crops, especially in sub-Saharan Africa (SSA). A meta-analysis of 82 studies was carried out to evaluate the response of major cereal crops, viz. wheat, maize, barley, teff, and sorghum, to nitrogen fertilization in Ethiopia. The results showed that N-application significantly increased yields of all the five crops examined herein. The average yields of the treatment effects over controls for the five crops were 3775.8 kg∙ha<sup>−1</sup> and 2593.3 kg∙ha<sup>−1</sup>, respectively. The overall yield response to nitrogen treatments for all the crops was 64.8% (wheat, 96.5%;maize, 40.65%;barley 84.36%;teff, 50.48%;and sorghum;23%). Overall, nitrogen agronomic efficiency (AE<sub>N</sub>) and partial factor productivity (PFP<sub>N</sub>) were 18.2 and 71.81 kg∙kg<sup>−1</sup>, respectively. A downtrend of nitrogen use efficiency with an increase in N rate was realized. The yield response was higher for the nitrogen treatment effects of >100 kg∙N∙ha<sup>−1</sup> (123.9%), clay soils (75.46%), low initial soil organic carbon (SOC) and available phosphorous (AP) (92.4% and 101.6%), respectively, Therefore, we recommend the application of nitrogen fertilizer (>100 kg∙N∙ha<sup>−1</sup>), especially on infertile soils for improved grain yield and NUE in aforementioned cereal crops in Ethiopia and similar regions in sub-Saharan Africa (SSA).展开更多

Focused on the sensitivity of backscatter from the scatterometer measurement and advanced synthetic aperture radar (ASAR) images to cereal parameters of rice, nine acquisitions, including rice parameters related eco-physiological variables and scattering coefficients, have been carried over the paddy field corresponding to rice growth stages. This paper analyzes the relationship between the corresponding backscatter to the cereal parameters based on the measurement at the interesting bands, polarizations, and incidence angels. Further, a modified water cloud model is built based on the ground measurement and advanced integrated equation model (AIEM), and then cereal parameters from ASAR images are retrieved and verified. The research results show that the sensitivity of backscatter to cereals from the sensor of the radar scatterometer could be helpful to build the retrieve model for synthetic aperture radar (SAR) images, which can achieve the scientific goals of the joint monitoring of ground and sky for cereal crops.展开更多

They included the Sorghum stovers (SS) and its threshed head residues (STH), millet stovers (MS) and its threshed head residues (MTH), corn stover (CS), wheat (WS) and barley (BS) straws. A legume crop residue (lentil, Lens esculanta, straw;LS) was included for comparison with the cereal crop residues. The CS was high (P crude protein (CP) and acid detergent lignin (ADL) and the lowest (P < 0.05) in Neutral Detergent Fibre (NDF) and acid detergent fibre (ADF) when compared to the amounts in SS and MS. It was found out that LS had higher (P < 0.05) CP, ADL, ME and low (P < 0.05) NDF and ADF than the cereal crop residues. There were differences in digestible DM (DMD) at various incubation times both between and within the feed samples. The DM and OM a, c fraction were highest (P < 0.05) for LS when compared to all the cop residues evaluated. The BS and MS had the lowest effective degradability (ED) DM at 0.02 and 0.05 (P < 0.05) rates of passage, while the LS had the highest. The chemical composition and degradability of different crop residues found in Eritrea indicate the potential the residues have in supplementing grazing animals.展开更多

The exact mechanism of action of these components is not completely understood,but extensive evidence suggests the antioxidants that are present in the grains are the likely source of benefits. These activities or properties might protect against coronary heart disease and diabetes. The relationships of complex carbohydrates,whole grain products and the prevention of diseases,including type2 diabetes mellitus and coronary heart disease continue to challenge the scientific community. Though cereal grains contribute to a healthy diet there are some people that can not tolerate the proteins present in the grain. This can lead to food allergies and when severe can be diagnosed as celiac disease.展开更多

In the Southeastern US, rye is traditionally grown for winter grazing in dormant bermudagrass pastures, where alfalfa (Medicago sativa L.) is increasingly planted as a companion crop. The effect of cereal rye on alfalfa as a succeeding crop is not known. Therefore, the objective of this study was to evaluate the effect of cereal rye on alfalfa seedling emergence, growth, forage yield, and weed suppression in field conditions. Rye was planted in the fall (mid-October) and the biomass was harvested in spring (March) followed by disking and incorporation of the remaining stubble in the soil. Alfalfa seed was planted four weeks later. The experiment design was a split-plot design with the main plots being no-rye and after-rye and the sub-plots being alfalfa cultivars. Ten alfalfa cultivars were planted in three replications after-rye and three replications with no-rye as a previous crop. In the establishment year, weed density was significantly (p < 0.01) lower in the after-rye alfalfa plots by nearly 77%. Alfalfa seedling counts were also significantly lower (p 0.01) among the cultivars planted in the after-rye block compared to the no-rye, with a seedling count reduction between 35% and 64%. Reduction in total dry biomass yield varied from 15% to 43% among the cultivars planted in the after-rye block. The results of this study also suggest that the allelopathic effect of rye on alfalfa may not persist beyond the establishment season, but the enormous yield reduction in the first production season may constitute a costly economic penalty in terms of forage production. There was variation in the response of different alfalfa cultivars to the effect of rye residue as indicated by the variation in the magnitude of reduction in stand count and forage yield. This warrants more research in multi-location trials with and without rye in order to establish whether there is genetic variation in alfalfa germplasm in their tolerance to cereal rye allelopathy.展开更多

文摘China is a leading country in the production of several minor cereals such as foxtail millet,Job's tears,naked oat,and naked barley.Sorghum and proso millet have also contributed greatly to Chinese agriculture.Foxtail millet,sorghum,barley,and proso millet were widely grown as major crops 60 years ago,and the reduction in their cultivation area reflects historical changes in Chinese agriculture over the past decades.Systematic germplasm collections from the 1950 s to the 1990 s gathered more than 66,690 accessions of these minor cereals,and for some of them,the Chinese germplasm collections are the largest in the world;for example,the 27,700 accessions of foxtail millet.Germplasm evaluations of each cereal species have focused mainly on drought tolerance,nutritional quality,and resistance to their main diseases.Comparisons among lines and selection of those with desirable traits were the main breeding methods for minor cereals in the 1950 s and 1960 s,but these methods were replaced by crossbreeding in the 1970 s.Newly developed cultivars have greatly changed the production situation,and many super cultivars have become milestones in crop breeding history.In this review,we describe the distribution and ecoregions,origin and domestication,and landmark varieties of several minor cereals in China.Nearly all of the minor cereals are drought-tolerant and fertilizer-efficient.The requirements for environmentally friendly crops and a more diverse food supply for humans and animals provide new opportunities to cultivate minor cereals in the drier and warmer environmental conditions that are predicted in the future.

文摘AIM: To comprehensively review and quantitatively summarize results from intervention studies that examined the effects of intact cereal dietary fiber on parameters of bowel function. METHODS: A systematic literature search was conducted using Pub Med and EMBASE. Supplementary literature searches included screening reference lists from relevant studies and reviews. Eligible outcomes were stool wet and dry weight, percentage water in stools, stool frequency and consistency, and total transit time. Weighted regression analyses generated mean change(± SD) in these measures per g/d of dietary fiber. RESULTS: Sixty-five intervention studies among generally healthy populations were identified. A quantitative examination of the effects of non-wheat sources of intact cereal dietary fibers was not possible due to an insufficient number of studies. Weighted regression analyses demonstrated that each extra g/d of wheat fiber increased total stool weight by 3.7 ± 0.09 g/d(P < 0.0001; 95%CI: 3.50-3.84), dry stool weight by 0.75 ± 0.03 g/d(P < 0.0001; 95%CI: 0.69-0.82), and stool frequency by 0.004 ± 0.002 times/d(P = 0.0346; 95%CI: 0.0003-0.0078). Transittime decreased by 0.78 ± 0.13 h per additional g/d(P < 0.0001; 95%CI: 0.53-1.04) of wheat fiber among those with an initial transit time greater than 48 h.CONCLUSION: Wheat dietary fiber, and predominately wheat bran dietary fiber, improves measures of bowel function.

文摘Cereals and oilseeds are the foundation of human survival which have attracted much attention due to their nutritional and functional properties for maintaining the healthy life. There are abundant varieties of cereals and oilseeds, however, for a long time, their process suitabilities are still unknown, resulting in the lack of precision processing. This paper summarized the characteristics of cereals and oilseeds, including sensory, physicochemical and processing qualities, their characteristic fingerprinting and products qualities. Furthermore, the quality fast detection method was also analyzed. It also explored the role of mathematical model and the standard evaluation index to determine the process suitability and discussed the opportunity for advanced model capability. We also prospected on scientific problems for expanding the predictive capabilities for processing suitabilities of these abundant varieties, focusing on the better results and advancements towards the processing of cereals and oilseeds products and improvement of their quality.
文摘Infant rice cereals were analyzed for total arsenic, inorganic arsenic (i-As) and the organic arsenic species monomethylarsonoic acid (MMA) and dimethylarsinic acid (DMA) using liquid chromatography inductively coupled plasma mass spectrometry (LC-ICP-MS). Total arsenic concentrations in the samples ranged from 110 ng/gup to 420 ng/g. The i-As in the rice cereals accounted for 33% to 77% of the total arsenic. The observed variability between infant rice cereals makes a dietary survey approach to accessing arsenic exposures difficult.

文摘Cereal aphids are major insect pests of wheat,which cause significant damages to wheat production.Previous studies mainly focused on the resista nee of differe nt wheat varieties to one specific aphid species.However,reports on the physiology and defense responses of wheat to different cereal aphids are basically lacking.In this work,we studied the feeding behavior of three cereal aphids:the grain aphid,Sitobion avenae(Fabricius),the greenbugs,Schizaphis graminum(Ron dani),and the bird cherry-oat aphid,Rhopalosiphum padi(Linn aeus)on win ter wheat,and the physiology and defense responses of wheat to the infestation of these cereal aphids with focus on how these cereal aphids utilize divergent strategies to optimize their nutrition requirement from wheat leaves.Our results indicated that S.graminum and R.padi were better adapted to penetrating phloem tissue and to collect more nutrition than S.avenae.The harm on wheat physiology committed by S.graminum and R.padi was severer than that by S.avenae,through reducing chlorophyll concentration and interfering metabolism genes.Furthermore,cereal aphids manipulated the plant nutrition metabolism by increasing the relative concentration of major amino acids and percentage of essential amino acids.In addition,different cereal aphids triggered specific defense response in wheat.All of these results suggested that different cereal aphids utilize diverge nt strategies to cha nge the physiological and defe nse resp on ses of their host plants in order to optimize their nutriti on absorption and requireme nt.These fin dings not only exte nd our current knowledge on the insect-pla nt in teractions but also provide useful clues to develop no vel biotech no logical strategies for enhancing the resistance and toleranee of crop plants against phloem-feeding insects.
文摘Diabetes is a metabolic disorder by a chronic hyperglycemic condition because of defects in insulin secretion and insulin action or both. Minor cereals are often drought tolerant and fertilizer efficient. In this review we focus the content and bioavailability of phytochemicals in some minor cereals on the basis evidence for increasing plasma phytochemical concentrations and reducing oxidative stress as well as inflammation in humans. Phenolics and Flavanoids are major phytochemicals and may be available with high concentration in minor cereals but as tightly attached with cell wall, their bioavailability is mostly limited. Clinical trials concluded that vitamin E and other common antioxidants were not helpful for managing diabetic complications. Vicious cycles can cause type 1 DM, where as hypoglycemia can forward to down and regulate neuroendocrine. Increased phytochemical bioavailability may be achieved through bio processing of grains but the improvements might be small and have not yet led to changes in clinical associated with reduced risk of T2D. Furthermore, the effects of minor cereals against oxidative stress in healthy individuals can be very low or not occurred but systemic inflammation can be reduced in people after huge intake. More than 300 Indian medicinal plants have antidiabetic property but exact mechanisms for hypoglycemic action of many plants are still unknown. Further studies are required to pay attention toward direct role of minor cereal phytochemicals on alarming diseases diabetes.
文摘Protein-energy malnutrition among children is the major health challenges and it may be related to low nutritional quality of traditional complementary foods and high cost of quality protein-based complementary foods. The aim of this study was formulation, preparation and evaluation of low-cost extruded products based on cereals and pulses. Composite flours were prepared using cereals and pulses, then formulated and extruded by a twin screw extruder in Osmania University, Hyderabad, India. Data were analyzed by SPSS software. Results showed: the protein contents of extruded formulas B, D and F were in the highest values. Carbohydrate in the extruded formula A was significantly higher than others. The lowest amount of ash and crude fiber were observed in the formula A. Content of energy in the extruded formulas E, F and C was higher;mean (SD) of Fe content in the extruded formula B, D and F was in the higher ranks among others. Calcium content in the extruded formulas C, E and F was in the highest amounts. Magnesium content in the extruded formulas B, D and F was higher than others. Cu content in the extruded formula C, D, B and F was higher than others. Manganese content in the extruded formulas B, C and F, and zinc content in the formulas B, D and F were higher than others. Tap density showed the lowest amount in the formula B, D and F, while their bulk density was higher. WHC was in the highest amount in the extruded formula A, while WSI in the extruded formula B, D and followed by F was in the highest amount. The mean scores of sensory evaluation of extruded products F showed that this combination has significantly better colour, flavour, texture and overall acceptability than others.
文摘The crop production in Ethiopia is markedly constrained by soil nutrient depletion and limited fertilizer input. Nitrogen is among the most yield-limiting factors of cereal crops, especially in sub-Saharan Africa (SSA). A meta-analysis of 82 studies was carried out to evaluate the response of major cereal crops, viz. wheat, maize, barley, teff, and sorghum, to nitrogen fertilization in Ethiopia. The results showed that N-application significantly increased yields of all the five crops examined herein. The average yields of the treatment effects over controls for the five crops were 3775.8 kg∙ha<sup>−1</sup> and 2593.3 kg∙ha<sup>−1</sup>, respectively. The overall yield response to nitrogen treatments for all the crops was 64.8% (wheat, 96.5%;maize, 40.65%;barley 84.36%;teff, 50.48%;and sorghum;23%). Overall, nitrogen agronomic efficiency (AE<sub>N</sub>) and partial factor productivity (PFP<sub>N</sub>) were 18.2 and 71.81 kg∙kg<sup>−1</sup>, respectively. A downtrend of nitrogen use efficiency with an increase in N rate was realized. The yield response was higher for the nitrogen treatment effects of >100 kg∙N∙ha<sup>−1</sup> (123.9%), clay soils (75.46%), low initial soil organic carbon (SOC) and available phosphorous (AP) (92.4% and 101.6%), respectively, Therefore, we recommend the application of nitrogen fertilizer (>100 kg∙N∙ha<sup>−1</sup>), especially on infertile soils for improved grain yield and NUE in aforementioned cereal crops in Ethiopia and similar regions in sub-Saharan Africa (SSA).

文摘The joint monitoring of the ground and sky for cereal crops based on microwave data has become a popular method for researches on earth surface objects. Focused on the sensitivity of backscatter from the scatterometer measurement and advanced synthetic aperture radar (ASAR) images to cereal parameters of rice, nine acquisitions, including rice parameters related eco-physiological variables and scattering coefficients, have been carried over the paddy field corresponding to rice growth stages. This paper analyzes the relationship between the corresponding backscatter to the cereal parameters based on the measurement at the interesting bands, polarizations, and incidence angels. Further, a modified water cloud model is built based on the ground measurement and advanced integrated equation model (AIEM), and then cereal parameters from ASAR images are retrieved and verified. The research results show that the sensitivity of backscatter to cereals from the sensor of the radar scatterometer could be helpful to build the retrieve model for synthetic aperture radar (SAR) images, which can achieve the scientific goals of the joint monitoring of ground and sky for cereal crops.
文摘Dietary fiber-degrading enzyme supplementation in broilers aims at off-setting the anti-nutritive effect of non-starch polysaccharides and at promoting broiler health.Recently,we demonstrated that xylanase/glucanase addition in wheat-based diet improved nutrient digestibility,arabinoxylan fermentability and broiler growth.Conversely,maize arabinoxylan was found to be recalcitrant to xylanase action.These findings suggested that enzyme-mediated improvement of nutrient digestion and carbohydrate fermentation depended on the cereal type present in the diet,and may have contributed to broiler growth.Hence,we aimed at further investigating the link between dietary enzymes and carbohydrate fermentation in broilers,by studying the impact of enzyme supplementation in cereal-based diets,to the microbial communities in the ileum and ceca of broilers.For that purpose,96 one-day-old male broilers were randomly reared in two pens and received either wheat-based or maize-based starter and grower diets.At d 20,the broilers were randomly assigned to one out of four dietary treatments.The broilers received for 8 d the wheat-based or maize-based finisher diet as such(Control treatments;WC,MC)or supplemented with a xylanase/glucanase combination(Enzyme treatments;WE,ME).At d 28,samples from the digestive tract were collected,and the ileal and cecal microbiota composition was determined by 16S ribosomal RNA gene amplicon sequencing.A similar phylogenetic(alpha)diversity was observed among the four treatments,both in the ileal and the cecal samples.Furthermore,a similar microbial composition in the ileum(beta diversity)was observed,with lactobacilli being the predominant community for all treatments.In contrast,both cereal type and enzyme supplementation were found to influence cecal communities.The type of cereal(i.e.,wheat or maize)explained 47% of the total variation in microbial composition in the ceca.Further stratifying the analysis per cereal type revealed differences in microbiota composition between WC and WE,but not between MC and ME.Furthermore,the prevalence of beneficial genera,such as Faecalibacterium and Blautia,in the ceca of broilers fed wheat-based diets coincided with arabinoxylan accumulation.These findings indicated that fermentable arabinoxylan and arabinoxylo-oligosaccharides released by dietary xylanase may play an important role in bacterial metabolism.
文摘The chemical composition and in situ dry matter (DM) and organic matter (OM) degradability of seven different cereal crop residues were evaluated in this study. They included the Sorghum stovers (SS) and its threshed head residues (STH), millet stovers (MS) and its threshed head residues (MTH), corn stover (CS), wheat (WS) and barley (BS) straws. A legume crop residue (lentil, Lens esculanta, straw;LS) was included for comparison with the cereal crop residues. The CS was high (P crude protein (CP) and acid detergent lignin (ADL) and the lowest (P < 0.05) in Neutral Detergent Fibre (NDF) and acid detergent fibre (ADF) when compared to the amounts in SS and MS. It was found out that LS had higher (P < 0.05) CP, ADL, ME and low (P < 0.05) NDF and ADF than the cereal crop residues. There were differences in digestible DM (DMD) at various incubation times both between and within the feed samples. The DM and OM a, c fraction were highest (P < 0.05) for LS when compared to all the cop residues evaluated. The BS and MS had the lowest effective degradability (ED) DM at 0.02 and 0.05 (P < 0.05) rates of passage, while the LS had the highest. The chemical composition and degradability of different crop residues found in Eritrea indicate the potential the residues have in supplementing grazing animals.
文摘Cereal grains can contribute to maintain health and prevent chronic diseases by supplying biologically active components. The exact mechanism of action of these components is not completely understood,but extensive evidence suggests the antioxidants that are present in the grains are the likely source of benefits. These activities or properties might protect against coronary heart disease and diabetes. The relationships of complex carbohydrates,whole grain products and the prevention of diseases,including type2 diabetes mellitus and coronary heart disease continue to challenge the scientific community. Though cereal grains contribute to a healthy diet there are some people that can not tolerate the proteins present in the grain. This can lead to food allergies and when severe can be diagnosed as celiac disease.
文摘Cereal rye (Secale cereale L.) is widely used as cover crop because of its allelopathic effects and effectiveness in weed suppression. In the Southeastern US, rye is traditionally grown for winter grazing in dormant bermudagrass pastures, where alfalfa (Medicago sativa L.) is increasingly planted as a companion crop. The effect of cereal rye on alfalfa as a succeeding crop is not known. Therefore, the objective of this study was to evaluate the effect of cereal rye on alfalfa seedling emergence, growth, forage yield, and weed suppression in field conditions. Rye was planted in the fall (mid-October) and the biomass was harvested in spring (March) followed by disking and incorporation of the remaining stubble in the soil. Alfalfa seed was planted four weeks later. The experiment design was a split-plot design with the main plots being no-rye and after-rye and the sub-plots being alfalfa cultivars. Ten alfalfa cultivars were planted in three replications after-rye and three replications with no-rye as a previous crop. In the establishment year, weed density was significantly (p < 0.01) lower in the after-rye alfalfa plots by nearly 77%. Alfalfa seedling counts were also significantly lower (p 0.01) among the cultivars planted in the after-rye block compared to the no-rye, with a seedling count reduction between 35% and 64%. Reduction in total dry biomass yield varied from 15% to 43% among the cultivars planted in the after-rye block. The results of this study also suggest that the allelopathic effect of rye on alfalfa may not persist beyond the establishment season, but the enormous yield reduction in the first production season may constitute a costly economic penalty in terms of forage production. There was variation in the response of different alfalfa cultivars to the effect of rye residue as indicated by the variation in the magnitude of reduction in stand count and forage yield. This warrants more research in multi-location trials with and without rye in order to establish whether there is genetic variation in alfalfa germplasm in their tolerance to cereal rye allelopathy.
