摘要: 木本彩叶植物叶色鲜艳, 具有极高的观赏价值, 能为园林景观增添色彩。近年来, 园林景观设计越来越重视木本彩叶植物的应用。引起叶色变化的直接原因是叶片中的色素含量与比例改变。叶色变异受内部遗传因素和外界环境因素共同影响, 通过控制光照和温度等条件可对叶色进行调控。随着对木本植物叶色变异机制研究的探索, 目前在木本植物中已挖掘出多个调控叶色变异的关键基因和调控模式。该文从环境因素、叶片微观结构、叶色变异的分子机制等方面总结木本彩叶植物叶色变异的研究进展, 为进一步完善木本植物叶色变异机制及培育观赏彩叶树种提供参考。

Abstract: Colorful woody plants have bright foliage, high ornamental value, and are valuable to the garden landscape. In recent years, more and more attention has been paid to the configuration of colored woody plants in landscape design. The most direct cause of leaf color change is the alteration in pigment content and ratio in the leaves. Leaf color variation is influenced by both genetic and environmental factors. Leaf color can be regulated through controlling light, temperature and other factors. With the development of molecular biology, several key genes for regulating leaf color variation have been discovered in woody plants. Here, we summarize the progress of researches related to leaf color variation in woody plants, including studies on environmental factors, leaf microstructure, and molecular mechanism of leaf color variation and related genes, so as to provide a theoretical basis for further improving our understanding on the mechanism of leaf color variation in woody plants and cultivating additional ornamental colored woody trees.
