| 摘 要： | 研究了干旱胁迫对美国无芒雀麦和本地无芒雀麦光合作用的影响。结果表明：关国无芒雀麦的光合速率基本上随着干旱梯度的增加而逐渐下降，在不同胁迫天数间也逐渐下降，但下降幅度较小；本地无芒雀麦各干旱处理光合速率在胁迫前中期随胁迫梯度的增加下降不明显，到胁迫后期才表现出较为明显的下降趋势，但在各胁迫天数间差别不大，仅在胁迫第20d各处理光合速率较之前有较为明显的降低。可见干旱胁迫对同化作用有很强的抑制作用，从而影响了植物的生长发育。

| Abstract: | The effects of drought stress on the photosynthesis of B.stamineus and B.inermis were studied.The results showed that the photosynthetic rate of B.stamineus decreased with the increasing of the drought gradient,but the decrease amplitude was less.The photosynthetic rate of B.inermis decreased indistinctively with the increasing of the drought gradient in the prometaphase,decreased distinctively in the later stage.The drought stress inhibited the assimilation strongly,which affected the plant growth and deve... |
