| Abstract: | Effects of zinc on carbon metabolism and its enzymes activities in leaves of balsam pear were studied by field trial . The results show that in the control plants stressed under a low level of zinc, there appear lower contents of sucrose, soluble sucrose ,starch and zinc, lower activities of carbonic anhydrase(CA) and sucrose phosphate synthase (SPS). How- ever , the activities of amylase, acid invertase(AI)and neutral invertase (NI)in the upper and lower leaves are higher in CK than in other treatments. There is a significant correlation between the physiological properties. |
