摘　　要：[目的]探究PLC在暗调控的气孔运动中的作用。[方法]采用药理学试验和气孔分析,研究PLC参与暗诱导的气孔关闭的作用。[结果]U73122阻止暗诱导的气孔关闭;L-NAME和c-PTIO能够逆转暗诱导的气孔关闭。[结论]暗中PLC活性较高。PLC与NO可能存在某种联系。[ Objective ] To study the role of PLC in the dark-regulated stomatal movement. [ Method ] By means of pharmacological approach and stomatal analysis, PLC was involved in the dark-regulated stomatal closure. [ Result] The dark-induced stomatal closure could be blocked by U73122 and reversed by L-NAME and c-PTIO. [ Conclusion] The bio-aetivity of PLC was high in the darkness, and some relationship may exist between PLC and NO in stomatal movement.
