Abstract:
Taking ‘Red globe’ grape as test material,the effects of environment temperature variation within the facility on antioxidant properties of leaves through the modes of early cultivation in solar greenhouse,early cultivation in plastic-covered tunnel,and delayed cultivation in plastic-covered tunnel for ‘Red globe’ grape were studied.The results showed that high temperature was the reason for increase of soluble sugar and SOD content of leaves during the growing period of grape while low temperature was the condition for decrease of SOD content of leaves during the growing period of grape.When temperature rised,content of MDA within leaves would gradually increase,and when the temperature fell,content of MDA would gradually decreased.Higher temperature and lower temperature all led to the increase of soluble protein,proline and POD content within grade leaves.Ground temperature greatly affected POD activity of leaves during the growing period of grape.The lowest POD activity could be found when the ground temperature was 16~17℃ while POD activity was higher when air temperature was above 18℃ or below 15℃.
