彩叶树种研究与开发利用现状

Research Status,Development and Utilization of Color-Leaf Trees

彩叶树种是园林植物的重要组成部分,因其较高的观赏价值在园林绿化中应用越来越广泛。介绍彩叶树种概念和分类的基础上,着重阐述了彩叶树种在野生资源、引种驯化、品种选育、光合特性、呈色机理等方面研究的国内外现状,分析了我国彩叶树种在园林应用和配置过程中存在的一些问题,并对彩叶树种的未来研究方向进行了展望,以期为彩叶树种的研究提供科学依据。

Colored-leaf trees,an important part of the landscape plants,have been extensively used in landscaping due to their great ornamental value.Through introducing the conception and classification of the colored-leaf trees,this article emphatically elaborates the research status at home and abroad of colored-leaf trees in wild resources,introduction and domestication,variety breeding,photosynthetic characteristics and colouration mechanisms.Moreover,the existing problems in the development and utilization of colored-leaf trees are analysed,and the future research direction of colored-leaf trees is discussed.This thesis provides a scientific basis for future studies on colored-leaf trees.
