为了缓解豫西旱地烟田干旱缺水以及烤烟产质量不稳定等问题,在洛阳烟区设置保水剂不同施用量田间试验处理,T1(CK):当地常规栽培措施(不施保水剂),T2:保水剂15kg·hm^(-2),T3:保水剂30 kg·hm^(-2),T4:保水剂45 kg·hm^(-2)... 为了缓解豫西旱地烟田干旱缺水以及烤烟产质量不稳定等问题,在洛阳烟区设置保水剂不同施用量田间试验处理,T1(CK):当地常规栽培措施(不施保水剂),T2:保水剂15kg·hm^(-2),T3:保水剂30 kg·hm^(-2),T4:保水剂45 kg·hm^(-2),探究保水剂对豫西烟田土壤水分、养分、烤烟生长、化学质量以及经济性状的影响。结果表明:T4和T3较CK可以显著提高烤烟生育期各时期内的土壤含水率、碱解氮含量、速效磷含量、速效钾含量和有机质含量;施用保水剂可以提高烤烟的总糖、还原糖、钾、类胡萝卜素类、棕色化产物和新植二烯的含量,降低烟碱、氯、芳香族氨基酸类和类西柏烷类的含量,提高烤烟的糖碱比和钾氯比,协调烟叶中性致香成分,提高烟叶质量;T4和T3的烤烟产量较CK显著增加12.79%和10.25%;T4、T3和T2的烤烟产值较CK显著增加15.07%、15.25%和4.51%。在保水剂施用量30kg·hm^(-2)的条件下,土壤速效养分较好,烤后烟的化学质量和经济效益最佳。 展开更多

Elevation affects the contents of polyphenols involved in the plants’resistance to the environment.In this study,polyphenolic contents,as well as the activity of polyphenol oxidase(PPO),were evaluated in mature cigar plants at different elevation levels.The results showed that:(1)The contents of chlorogenic acid,rutin,and scopolamine in cigar leaves increased gradually at all elevation levels,reaching a maximum 25 d after the mature stage.(2)With an increase in altitude,the polyphenolic compounds’contents increased,having the lowest values at 350 m height and the highest at 1090 m height.(3)As for the PPO activity in cigar leaves,the general trend showed an increase first followed by a decrease in activity during the mature period.(4)PPO activity in the leaves of cigar plants planted at 840 m height was substantially elevated compared to those growing at 600 m and 350 m height.Interestingly,the leaves planted at 1090 m height had the lowest PPO activity.(5)There were significant positive correlations between altitude and the contents of chlorogenic acid,rutin,and scopolamine within the plants leaves.Altitude negatively correlated the proportion of chlorogenic acid and scopolamine whereas positively correlated rutin proportion within the total polyphenols.Temperature had negative correlations with the contents of chlorogenic acid,rutin,and scopolamine,while sunlight intensity had positive correlations on their contents.Conversely,there were no significant correlations between altitude,temperature,and light intensity on PPO activity.Therefore,this study can provide valuable insight and a theoretical basis for the production of premium cigars. 展开更多

MicroRNAs(miRNAs) are small(ca. 20-24 nucleotides) non-coding RNAs that have recently been recognized as key post-transcriptional modulators of gene expression;and they are involved in many biological processes in plants, such as root growth and development. The miRNAs regulate root elongation, lateral root(LR) formation and adventitious root(AR) development in response to hormone signaling, nutrient uptake and biotic/abiotic stress. This review provides multiple perspectives on the involvement of miRNAs in regulating root growth and development in plants. We also discuss several crucial mechanisms of miRNAs, their relationships with transcription factors and the target gene-mediated hormone signaling interactions in the regulation of root growth and development. 展开更多
