[CO2]和温度增加的相互作用对植物生长的影响

The global environment is changing with increasing temperature and atmospheric carbon dioxide concentration. Because the two factors are concomitant and the rise of global carbon dioxide concentration will affect all biomass across the full global range of temperatures, we review the theory regarding and observations on the effects of temperature and carbon dioxide concentration interactions onplant carbon balance, growth, development, biomass accumulation and yield. Although there are sound theoretical reasons for expecting a large stimulation of net CO 2 assimilation rates by increased \[CO 2 \] at higher temperatures, this does not necessarily mean that the pattern of biomass and yield responses to increasing \[CO 2 \] and temperature are determined by this response. This paper reviews the interactions between the effects of \[CO 2 \] and different temperatures on plants. There is little unequivocal evidence for large differences in response to \[CO 2 \] at different temperatures, as studies are confounded by the different responses of the species adapted and acclimated to different temperatures, and the interspecific difference in growth form and development pattern. It is coueluded that stress we should the importance of initiation and expansion of meristems and organs and the balance between assimilate supply and sink activity in determining the growth response to increasing \[CO 2 \] and temperature.
