| 摘 要： | 滴灌施肥条件下,对南疆‘红富士’苹果的光合特性的日变化特征进行了研究。苹果净光合速率日变化曲线呈"双峰"型,光合作用存在明显的"午休"现象。蒸腾速率日变化呈单峰曲线,变化趋势与气孔导度基本相同。水分利用效率表现为早晚高、中午低。

| Abstract: | This article studied the diurnal variation of photosynthetic characteristics on red ‘Fuji’ apples in the south of Xinjiang.The results indicated that diurnal variation curve of photosynthetic rate was double-peak and appeared obvious phenomenon of the midday depression.The diurnal variation of Tr was single peak curve and similar to the Gs.The diurnal variation curve of WUE showed high in the morning and evening while low at noon. |
