Abstract

Research on responses of morphology to elevated CO₂ and temperature is an important content in the context of climate change. Therefore, this review firstly described the definition and conceptual framework of morphology. Then, the effects of elevated CO₂, temperature and the combination of two on plant height, branching, crown shape, leaf and root system traits were summarized. The previous results showed that elevated CO₂ stimulated the growth of branch, stem and internode length, resulting in the change of crown architecture. The effects of elevated temperature alone or combination of elevated CO₂and temperature on plants were various depending on functional groups, species and regions. Moreover, differences and their possible reasons in research results were discussed. In the end, we analyzed the recent research, then indicated the emphasis and direction of future study on reinforcing study on the mechanism of change in morphology and the relationship between morphology and the function of ecosystem.

Key words： climate change CO2 concentration temperature morphology function
