摘　　要：不定根诱导发生是研究植物发育和形态建成的一个重要理论课题,也是优良林木无性繁殖、成功实现转基因材料植株再生以及加速林业产品原料植物规模化栽培的关键问题。植物不定根的发生是一个十分复杂且多因素影响的过程,是植物体内的内源因素和体外的外源因子共同作用的过程。该研究通过归纳国内外关于不定根发生的形态解剖、生理生化、植物分子方面的研究进展,分析不定根发生过程中存在的不同影响因素及其影响效果,以期为植物不定根诱导研究提供有力的理论依据,并为实践中植物无性繁殖诱导不定根提供参考依据。Rooting induction is an important theoretical subject in the study of plant development and morphogenesis.It is also a key issue in the asexual propagation of fine trees,the successful regeneration of transgenic plants and the acceleration of large-scale cultivation of forestry products.The occurrence of adventitious roots in plants is a complicated and complex process with multiple factors.Inducing plant adventitious roots has important practical significance in the asexual reproduction of plants.How to well induce the adventitious roots of a certain plant and establish its stable root-rooting mechanism is the direction of the problem that researchers have been searching for.This study dealed with the mechanism of the adventitious root,summarized the research progress in the physiology and molecular science of adventitious roots in domestic and abroad.The different factors influencing the mechanism of adventitious roots and their effects on the rooting of adventitious roots were analyzed in order to provide a strong theoretical basis and practical reference for the research on the induction of adventitious roots.
