Effect of Cu and As and their combination pollution on Glycine max

Abstract

Abstract: Experiments are carried out with hoagland cultivation to study the effects of Cu, As, their interactions on the germination, seedling growth of Glycine max. The results show that Cu or As pollution reduced proteinase activities,inhibited the seedling growth, the respiration rate of germinating seed of soybean.The inhibition increased as Cu, As concentration increased,POD activities increased with increasing Cu, As concentration.Cu pollution has an antagonistic effect against the pollution of As,and vise versa.

Key words: Cu, As, Glycine max, Seed germination, Seedling growth, Enzyme activity
