| Abstract: | Effects of elevated atmospheric CO_2 concentration and its cooperation with other environment factors on growth of plants, agricultural production and plant communities are discussed. With the enhancement of CO_2, photosynthesis rate and water use efficiency tend to be increased, but transpiration, respiration rate and stomatic conductance tend to be decreased. In addition, the effects of CO_2 enhancement on C3 and C4 plants are remarkably different. |
