摘要:: 在全球气候变化过程中，大气CO₂浓度不断升高，已从工业革命前的270 μmol^.L^-1升高到2013年的390 μmol^.L^-1，预计到本世纪末将达到700 μmol^.L^-1，CO₂浓度的快速升高将对大豆生产产生重要影响。本文从光合速率、叶面积、叶绿素含量、共生固氮、内源激素、以及干物质积累和大豆产量等方面综述了大气CO₂浓度升高产生的影响。大多数研究发现，随着大气CO₂浓度升高，大豆光合速率随之升高，但少数研究发现，随大气CO₂浓度升高，光合速率反而降低，这可能与植物对CO₂浓度升高的光合适应反应有关；叶绿素含量随CO₂浓度升高呈现增加趋势，但对一些夏大豆研究发现，叶绿素含量无明显变化；叶面积、共生固氮、干物质积累和产量也都对CO₂升高产生不同程度的响应，但响应程度因CO₂升高幅度、大豆品种、生育时期和其他试验条件而有所差异；有关于CO₂升高对内源激素影响的研究报导较少。针对未来所需要开展的研究，我们提出与光合作用相关酶学生理、内源激素以及碳氮代谢角度对CO₂影响大豆产量机制进行深入解析，而且在不同品种之间对CO₂浓度升高的响应进行分析，明确品种之间是否存在差异。这将对未来大豆高产育种，提高大豆生长的环境适应性有重要的理论价值；并提出了今后的研究方向。

Abstract:: During global climate change, the concentration of CO₂in the atmosphere has increased from 270 μmol?L^-1prior to the Industrial Revolution to 390 μmol^.L^-1in 2013.It is expected that CO₂will increase to 700 μmol^.L^-1?by the end of the century. The increase of atmospheric CO₂concentration is likely to affect soybean production. The impacts of elevated CO₂on photosynthetic rate, leaf area, chlorophyll content, phytohormones, nitrogen fixation, biomass accumulation and yield are reviewed.Many studies stated that photosynthetic rate of soybean had positive response to elevated CO₂, while a decrease trend was observed in other studies.This is likely due to photosynthetic acclimation in response to elevated CO_2.?Elevated CO₂generally facilitates the accumulation of the chlorophyll content, but there was no response in some summer-sowing cultivars of soybean. The magnitude of leaf area, nitrogen fixation, biomass and yield in response to elevated CO₂varied depending on the extent of CO₂rise, cultivars, growth stages and other experimental conditions. The information on the effect of elevated CO₂on phytohormones is very rare to our knowledge. It is worth further investigating on the mechanisms of yield in response to elevated CO₂, including enzyme activities in relevant photosynthetic physiology, and metabolisms of carbon and nitrogen etc.Such work is fundamental to the high-yield breeding and the improvement of environmental adaptability in soybean in the future.
