| 摘 要： | 本文研究了长期CO2加富对大豆叶片光系统Ⅱ(PSⅡ)功能的影响。结果表明，CO2加富能促进大豆叶片PSⅡ潜在活性和原初光能转化效率，以及电子传递量子产量的提高；增加荧光光化学淬灭组分，降低荧光非光化学淬火组分。CO2加富对大豆叶片PSⅡ功能的改善，可能是CO2加富条件下，大豆叶片光合速率的提高和产量增加的重要原因之—。

| Abstract: | The effects of long-term elevated CO2 on functions of PSⅡ in soybean leaves were studied. The results showed that the potential activity and efficiency of primary conversion of light energy of PSⅡ , quantum of PSⅡ electron transport were stimulated, photochemical quenching coefficient was increased and non-photochemical quenching coefficient was decreased under elevated CO2. The improvement of PSⅡ functions could be one of important factors which result in increases of the photosynthetic rate and yield of soybean under elevated CO2. |
