摘  要:
重瓣是观赏性植物开花器官的主要观赏性状之一,是影响开花植物观赏价值的一种极其重要的育种特征。文章主要叙述了重瓣花国内外的研究进展,并对重瓣花的各种起源方式进行总结。概述了花器官的ABC模型和ABCDE模型影响重瓣花形成的分子机制,阐述了外在因素温度、激素和叶片对花瓣重瓣性的影响。研究表明,重瓣性状的形成与重瓣的起源方式、分子机制及外界其他因素有关。重瓣花的研究为重瓣植物的发展及新品种的培育提供了理论基础,也为重瓣花的研究提供了参考依据。

摘  要:
Double flowers are one of the main ornamental characters of ornamental plants. This paper mainly describes the current research progress of double flowers at home and abroad, summarizes the various origins of double flowers. The molecular mechanism of the ABC model of flower organs and the ABCDE model affecting the formation of double flowers was overviewed, and the influence of external factors temperature,hormones and leaves on the re-petals of the petals was expounded. Study results showed that the formation of double flapping character was related to the origin of double flapping, molecular mechanism and other external factors. The research on double flowers provides the theoretical basis for the development of double petals and the cultivation of new varieties, as well as the reference for the research on double flowers.
