摘　　要：体胚发生技术是林木树种进行无性快繁的重要技术之一。本文概述了松属植物体胚发生在国内外的研究进展,分析了基因型、外植体和外源激素等在体胚发生过程中的作用,提出了体胚发生技术所存在的问题并指出了今后体胚发生技术研究的重要方向。Somatic embryogenesis is an important technique of vegetative propagation in tree species. This articlesummarized the research progress of somatic embryogenesis in conifer trees in domestic and overseas,analyzed the roles ofgenotypes,explants and exogenous hormones in somatic embryogenesis. The existing problems of somatic embryogenesiswere analyzed and the main work of the future research on somatic embryogenesis was pointed out.
