| 摘 要： | 土壤水分供应充足的晴天,苹果幼树叶片水分亏缺影响净光合效率(PN)。而且当PN处于低谷期时,同水分亏缺有关的超氧物歧化酶(SOD)和谷光甘肽过氧化氢酶(GSH PX)活性达到一天的顶峰。

| Abstract: | Leaf water deficits influents net photosynthesis efficiency (PN) of the apple leaves on a sunny day when there is enough water in soil. Furthermore, during the low PN the activity of both superoxide dismutase(SOD) and glutathione peroxidase(GSH-PX) reach the climax of the whole day. |
