Abstract
The changing patterns of APX activity in fruit were examined under high-temperature and excessive-light stress in a comparison of APX activity among fruits on different exposures of a canopy and also among different degrees of sunburned fruits,as well as by application with exogenous antioxidative formulations.The results indicated that there were very significant differences in APX activity among fruits on different exposures of a canopy with higher activity appearing in SW,S and W fruits,which was associated directly with fruit accclimation to high temperature and excessive light intensity under natural conditions.Within a certain range,APX activity increased with the degrees of sunburned fruits but decreased abruptly beyond a threshold limit,implying that APX was damaged itself as a result of extremely high temperature or excessive sunlight.Spraying fruits with different types of exogenous antioxidative formulations could improve APX activity,among which SA showed the best effect by a rise of more than 5 times,compared to the control.Therefore,it was concluded that spraying fruits with exogenous antioxidants could raise their APX activity,thus improving fruit antioxidative capability.
