Abstract

Abstract: Effects of exogenousAsA on ascorbate glutathione cycle and activity of GalLDH - akey enzyme for ascorbic acid biosynthesis were investigated during senescence of detached leaves of apple (Malus domestica Borkh. ‘Gala’) in this paper. The results showed that 5 mmol·L ^{- 1} exogenous AsA inhibited partially membrane lip id peroxidation and decreased H₂O₂ content, but had little effect on relative membrane permeability. Exogenous AsA maintained high activities of ascorbate peroxidase (APX) and dehydroascorbate reductase (DHAR) , but inhibited partially the activity decline ofmonodehydroascorbate reductase (MDHAR) ,and decreased ratio of oxidized glutathione (GSSG) , then increased AsA content and regeneration ability accordingly. However, exogenousAsA inhibited the activity of L-galactono-1, 4-lactone dehydrogenase ( GalLDH) in the beginning of senescence and decreased ability ofAsA synthesis, but latermaintained higher activity of GalLDH.
