| 中文摘要:在旱地条件下,对18个水旱地小麦品种开花期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,根据水势高低并不能将水旱地品种截然分开。有9个品种的水势于21:00,已恢复到最高点,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. |
