摘要
为了探讨番茄光合特性对CO2浓度变化的生态响应,在番茄生长季节,对2个番茄材料在不同CO2浓度条件下叶片的光合特性进行了分析。研究结果表明:随着CO2浓度的升高,2个番茄材料的光合量子利用效率出现逐渐升高的趋势,但呼吸作用和光补偿点却随CO2浓度的升高而出现下降的趋势;光合作用速率和光饱和点在CO2浓度低于800μl/L时随CO2浓度升高而增加,高于这一浓度则随CO2浓度升高而下降。
In order to investigate tomato photosynthetic response to changes of CO2 concentration, some photosynthetic traits of two tomato genotypes were determined under different CO2 concentration in growing season. The results lindicted quantum efficiency of two genotypes increased with enhancement of CO2 concentration, but respiration and light compensation point declined. Photosynthetic rate and light saturation point increased with enhancement of CO2 concentration which were in the range of no more than 800 μl/L; over this value, these traits decreased.
