Abstract: Plant phenotypic plasticity is the different phenotypic characteristics of the same genotype affected by different environments. It is a trade-offbetween plant traits and heterogeneous environments, and is an adaptation and expression of plants to the environment. Herein, we combing the development of research on phenotypic plasticity from an integrated, with a focus on the climate, geography and biology environmental factors that affect plasticity and its response mechanism. At the same time, several important directions for future research on plant phenotypic plasticity in the context of global climate change are summarized. It is believed that the research on phenotypic plasticity in China needs to be further deepened, especially the process and mechanism of multi-factor influence on plant plasticity.
