摘　　要：雄蕊瓣化是产生重瓣花的重要方式,在雄蕊完全瓣化而雌蕊未瓣化的情况下还可以产生雄性不育材料。人为诱导雄蕊瓣化可以快速获得重瓣观赏植物新品种,或获得雄性不育系用以简化杂交育种过程,降低杂交种子生产成本,提高种质创新和杂交育种效率。摸清雄蕊瓣化的形成机制是开展上述工作的前提,本文从影响雄蕊瓣化的外界因素、调控雄蕊瓣化的关键基因及其作用的分子机制等研究进展进行综述,旨在为后期开展相关研究,利用雄蕊瓣化开展高效育种提供参考。Stamen petaloidy is an important origin of double flowers.Male sterile materials can be produced while stamens completely convert into petaloid tissues when the pistil is still intact.Inducting stamen petaloidy can quickly obtain new double flower varieties of ornamental plants,or can simplify crossbreeding process by using male sterile lines,which will reduce the cost of hybrid seed production,and improve germplasm innovation and crossbreeding efficiency.To find out the formation mechanism of stamen petaloidy is the prerequisite for carrying out the above work.This paper reviewed the research progress of external factors affecting stamen petaloidy,key genes regulating stamen petaloidy and their molecular mechanisms,aiming at providing reference for later related research and efficient breeding by using stamen petaloidy.
