Abstract:
Taking melon variety ‘Qitian No.1’ as material,using pot experment,the effect of trehalose foliar spraying treatment on antioxidant system of melon was studied,in order to understand the effect of trehalose on salt tolerance of melon.The results showed that when NaCl stress was 0.4% and trehalose concentration was 0.4%,it significantly reduced melon O?[TX-*4]2 production rate,cell membrane permeability and MDA,significantly increased activities of SOD and POD.It showed 4% concentration of trehalose could effectively improve the ability of melon antioxidant system,and could effectively alleviate melon salt stress on the injury.
