Effects of exogenous silicon on antioxidant capacities in sub-cellular fractions of asparagus bean seedlings under rust stress
外源硅对锈菌诱导下豇豆叶片不同细胞器中抗氧化特征的影响

The effects of exogenous silicon(Si) on antioxidant ability of two asparagus bean cultivars,'ZN016'(highly resistant) and 'Zhijiang 282'(susceptible),were investigated at sub-cellular level(cytoplasm,chloroplast and mitochondria) under rust(Uromyces vignae) stress by substrate culture.The results indicate that application of exogenous Si significantly increased the activities of peroxidase(POD),ascorbate peroxidase(APX),catalase(CAT),and phenylalanine ammonia-lyase(PAL) in three sub-cellular fractions,and s...
