1.1 Effects of zinc on carbon metabolism and its enzymes activities in leaves of balsam pear
The results showed that the control plants under low zinc (effective zinc content 0.45 mg-kg1) exhibited a lower contents of sucrose, soluble sucrose ,starch and zinc, lower activities of carbonic anhydrase (CA) and sucrose phosphate synthase (SPS). However, the activities of amylase, acid invertase (AI) and neutral invertase (NI) in leaves were higher in ...
