| 摘 要： | 目的]明确富含海藻活性成分的海藻蒸腾抑制剂对龙爪槐叶片蒸腾效率和光合参数的影响。方法]研究叶面喷施不同蒸腾抑制剂对龙爪槐叶片光合特性及膜脂过氧化的影响。结果]与常规蒸腾抑制剂相比,叶面喷施富含海藻活性物质的海藻蒸腾抑制剂150倍稀释液,不仅能够有效抑制夏季高温条件下龙爪槐叶片的水分散失,维持较好的叶片水分状况,减轻水分胁迫的伤害,避免体内活性氧清除系统的紊乱,还能延缓叶片衰老,使叶片水平的蒸腾效率增加,同时对促进光合作用也具有一定效果。结论]试验结果为新型海藻蒸腾抑制剂在园林树木上抗干旱方面的应用提供了参考。

| Abstract: | Objective] The aim was to study effects of seaweed anti-transpirants on photosynthetic traits, membrane lipid peroxidation of So-phora japonica. Method] The effects of different anti-transpirants on photosynthetic traits, membrane lipid peroxidation of Sophora japonica were studied.Result] The results showed that, compared with the conventional anti-transpirants, 150 times liquid of seaweed anti-transpira-nts not only can effectively restrain water loss of Sophora japonica leaves under high temperature in summer, maintain a good leaf moisture sta-tus, reduce the damage of water stress, avoid the disorder of active oxygen scavenging system, but also can delay the leaf senescence, increase the transpiration efficiency, and have some effects on promoting photosynthesis. Conclusion] The results provide reference for application of new type seaweed anti-transpitants on drought resistance in garden trees. |
