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.
