摘　　要：气孔是植物与外界环境进行气体交换的通道。植物通过调节表皮气孔的开闭来优化气体的通过量,从而适应自身的生存环境。植物气孔开度的大小受干旱、CO2浓度、光照、湿度等多种环境因子控制。作为植物应答环境因子变化的良好模式,建立各种刺激与气孔运动的关系,将直接推动相关领域研究工作的深入开展,为解决目前和将来面临的农业生产和环境恶化问题,进而为培育高抗和农作物新品种提供重要的理论基础。主要综述了脱落酸、生长素、细胞分裂素、乙烯、水杨酸、茉莉酸这6种植物激素对气孔运动的调节,进而了解植物利用气孔来调节并适应环境变化的内在机制。Stomata mediate gas exchanges between plant and environment.Plants adjust the epidermis stomatal opening and closing to optimize the throughput of the gas,so as to adapt to its own survival environment.The size of the stomata opening is controled by the drought,CO2 concentration,light,humidity and other environmental factors.As a good model of plant response to envir-onmental factors change,establishing the relationship between all kinds of stimulating and the stomatal movement will directly promote the in-depth development of relevant field research work,in order to solve the current and future agricultural pro-duction and environmental degradation problems,to provide important theoretical basis for cultivating high and new crop varieties.This article mainly summarize the regulation of six kinds of plant hormones such as the abscisci acid,auxin,cytokinins,ethylene,salicylic acid and jasmonic acid impacted on stomatal movement,and then understand the internal mechanism that the plants use stomata to adjust and adapt to environmental changes.
