摘要
通过研究橄榄油加工废弃液对玉米种子萌发及幼苗生长的影响,为橄榄油废弃物利用以及农田环境保护提供参考。将橄榄油加工废弃液(10%~60%)用0.10%Na2CO3碱化处理,考察其对玉米种子萌发、幼苗生长以及生理生化特性的影响。30%碱化废弃液能显著促进玉米种子萌发和幼苗生长,随废弃液浓度升高,种子萌发率显著降低,幼苗生长和生物量受阻,幼苗整齐度降低,叶片O2^-·产生速率先升高后降低,H2O2、游离脯氨酸、可溶性糖和丙二醛含量显著增加,超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)和抗坏血酸过氧化物酶(APX)活性先升高后降低。该研究结果对橄榄油加工废液的处理与应用具有参考价值。
The purpose of this study is to study the effects of waste liquid from olive oil processing on the seed germination and seedling growth of Zea mays L.so as to provide references for the utilization of olive oil waste and farmland environmental protection.Olive oil processing waste liquid(10%-60%) alkalified with 0.10% Na2CO3,was applied to investigate the effects on seed germination,seedling growth and physiological and biochemical characteristics in maize.Alkalinized waste solution(30%) could significantly promote maize seed germination and seedling growth.With the increasing concentration of alkaline waste liquid,the germination rate was significantly reduced and seedling growth was blocked,biomass accumulation was limited,seedling uniformity was also decreased.O2-· producing rate and H2O2 content in the leaves increased significantly and the accumulation of free proline,soluble sugar and malondialdehyde in the seedlings was obvious.The activities of superoxide dismutase,peroxidase,catalase,and ascorbate peroxidase in the seedlings first increased and then decreased,which showed a trend of high concentration inhibition and low concentration induced enhancement.These results suggested that 30% alkalized waste liquid could effectively promote seed germination and seedling growth of maize.The results of this research provide important reference values for the processing and application of olive oil processing waste liquid.
