| 摘 要： | 在池栽防雨旱棚条件下研究了土壤水分胁迫对冬小麦光合及产量的影响。结果表明，随土壤水分胁迫加剧，小麦旗叶光合速率下降，气孔导度降低，籽粒灌浆速率下降，从而导致产量降低；但是，轻度胁迫与水分适宜处理之间，上述生理特性和籽粒产量均无显著差异，这就为节水高产提供了理论依据。

| Abstract: | Impacts of soil water stress on photosynthesis and yield of winter wheat were studied in pondlet culture with rain proof shelter.Results showed that the photosynthetic rate,stomatal conductance of flag leaf and the filling rate declined as water stress increased so that the grain yield declined.However,there were no significant yield reducing under light water stress and proper water management. This provided physiological explaination for production of water saving and high yield. |
