摘要:
以多年生黑麦草“爱神特2号”为试材，采用室内培养的方法，研究了在高温条件下保水剂对其光合特性的影响。结果表明：随着高温胁迫强度的增加和时间的延长，多年生黑麦草叶片的净光合速率、气孔导度、瞬时水分利用效率和光能利用效率持续下降。添加保水剂后，净光合速率、气孔导度、光能利用效率、瞬时水分利用效率均上升，蒸腾速率、胞间CO2浓度下降。说明添加保水剂可以延缓高温胁迫对植物光合作用的抑制作用。
Abstract:
Taking Lolium perenne L.‘Aishente 2’ as material，the effects of super absorbent polymer (SAP) on photosynthetic characteristics of it was investigated under high temperature stress.The results showed that under high temperature，net photosynthetic rate，stomata conductance，water use efficiency and light use efficiency of Lolium perenne L.decreased with high temperatures stress intensity and time increased.When adding SAP，net photosynthetic rate，stomata conductance，water use efficiency and light use efficiency went up remarkably.The adding of SAP brought the decreasing of transpiration rate and intercellular CO2 concentration as well.It was clearly shown that SAP would reduce the inhibitory effect of high temperature stress on the photosynthesis of plant.
