Abstract:
Under natural conditions，plants are exposed to different abiotic stresses.Fruit of Yali pears were taken as materials，in order to characterize the response of anti-oxidative systems to high temperature and excessive light，the reactive oxygen species (ROS) metabolism and the dynamic changes of antioxidant substance of Yali pears fruits were studied under light intensity and high temperature treatment，and different acclimating treatment.The results indicated that the rising of light intensity induced the increasing of H2O2 and DHA content，membrane permeability and POD activity，but the SOD,APX,GR and MDAHR activity and AsA content were inhibited.Without light acclimatization treatment，the H2O2 content of fruit was increased，but the oxidant enzyme(SOD,APX,GR，MDAHR) activity were not significantly changed.So that the membrane permeability of fruit under picking off leaves was higher than that of the exposure fruit of a tree outside canopy.
