摘　　要：诱导植物体细胞胚发生是一个多因素事件,其发生机理的研究也是多层次多方面的。本文从诱导体细胞胚的胁迫因子和体细胞的响应角度,分析了高浓度2,4-D、重金属、高渗透等胁迫因子对体细胞胚发生的诱导,以及体细胞产生的ABA、胼胝质沉积、几丁质酶活性增强、热激蛋白特异表达等生理响应,概述了植物体细胞胚发生的一些研究成果和理论认识。The induction of plant somatic embryogenesis in cultured tissue is a multi-factorial event,and the studies of its mechanism are also in various profiles and in different levels.In this review,in the side of the relationship between the stress factors induced somatic embryogenesis and the explants response to them,we summarize the induction role of stresses on the somatic embryogenesis：high concentration of 2,4-D,heavy metal,high osmotic pressure,and describe the physiology responding of explants to them in the level of ABA,callose deposition,higher activity of glucanase,special expression of some heat-shock proteins.The research results and theories on plant somatic embryogenesis were also reviewed.
