中文摘要：

彩斑植物在园林绿化工程实践中已被广泛应用，为丰富园林景观提供了不可或缺的素材。该文从遗传、质体结构、超微结构、生长发育、光合作用等方面综述了植物彩斑的形成机理；又从基因突变、转座子理论、植物进化、环境因素、生长分裂的不均衡性以及环境因素等方面指出了彩斑出现的原因，以期能为从事园林植物遗传育种工作的科研人员提供参考。

英文摘要：

Variegation plants had been widely used in landscape engineering and were an indispensable part of landscape. The variegation formation mechanism from these following aspects.genetic, plastid structure, uhrastructure, development and photosynthesis were overviewed in this paper, the reasons for variegation phenomenon, such as genetic variation, transpose on theory, biological evolution environmental factors and so on were also analyzed. The paper will be helpful for landscape practitioners to better understanding the variegation, especially for the genetics and breeding of landscape plants.
