| 摘 要： | 在旱地条件下，对１８个水旱地小麦品种开花旗旗叶水势昼夜变化研究表明，不同品种在不同时间的水势及其升降速率有明显差异，但不呈平行变化规律，根据水势高低并不地是地品种截然分开。有９个品种的水势于２１：００，已到最高点，另外９个品种于５：００达到最高。

| Abstract: | Under water stress conditions,flag leafcs water potential and its change rate have been studied in flowering period.There is much difference among eighten wheat varieties.But not all droughtresistant varieties have higher water potential,not all varieties get the highest water potential at daybreak; nine varieties get the highest water potential at nightfall,while water potential of the others fall by daybreak. |

| Keywords: | Wheat Water potential Change between day and night |
