Abstract:

Autumn leaf tree species are good materials for leaf viewing and landscape planning, which have application prospects in constructing seasonal landscape. The leaves of autumn leaf tree species change into red or yellow when the temperature is low. Anthocyanin is an intrinsic factor influencing leaf color, but its content is affected by a series of factors. In order to explore the influencing factors and regulation measures of color change of autumn leaf tree species, this paper reviewed the external environment, physical means, hormones, regulators, nutrients and other factors related to leaf color change, and discussed the research direction of color change regulation measures of autumn leaf tree species as well as the application of these measures. The study can provide a theoretical basis for further research on autumn leaf tree species.

Key words: autumn leaves, leaf color regulation, leaf discoloration
