摘要: 木本彩叶植物叶片颜色鲜艳, 有极高的观赏价值, 能够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配置。引起叶色变化的最直接原因是叶片中的色素含量与比例发生了改变。叶色变异受内部遗传因素和外界环境因子的共同影响。通过控制光照和温度等条件可对叶色进行调控。随着分子生物学研究的发展, 目前在木本植物中已经挖掘出多个叶色变异关键基因。本文将从环境因素、叶片微观结构、叶色变异分子机制及相关基因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、培育彩叶观赏树种提供理论基础。

Abstract: Woody color plants have bright foliage, high ornamental value, and have high values to the landscape. In recent years, more and more attention has been paid to the configuration of woody colorants in landscape design. The most direct cause of leaf color change is the alteration in pigment content and their ratio in the leaves. Leaf color variation is influenced by both internal heredity and external environmental factors. By controlling light, temperature and other conditions, leaf color can be regulated. With the development of molecular biology, several key genes for leaf color variation have been discovered in woody plants. Here, we summarized the progresses of research in leaf color variation in woody plants from the aspects of environmental factors, leaf microstructure, and molecular mechanism of leaf color variation and related genes, so as to provide a theoretical basis for further improving the mechanism of leaf color variation in woody plants and cultivating ornamental tree species with colored leaves.
