| 摘 要： | 研究了4个节瓜品种(系)的光合作用对光和CO2的响应。结果表明:14-2、特选4号和黄毛光饱和点较高,光补偿点较低,光饱和时最大净光合速率较大和表观量子效率较高,而粤科2号利用光能的效率较低;4个品种(系)的CO2补偿点比较接近,CO2饱和点粤科2号最高,14-2最低;14-2具有最高的CO2饱和时最大净光合速率和羧化效率,表明其对CO2利用效率较高。

| Abstract: | The response of leaf photosynthesis to light and CO_ 2 were studied in 4 chieh-qua(Benincasa hispida Cogn.var.chiehqua How.)cultivars.The results showed that there were higher light saturation point,lower light compensation point,higher maximum net photosynthetic rate(Pn)at saturated-light intensity and apparent quantum yield(AQY)in 14-2,Texuan No.4 and Huangmao,which indicated their higher light utilization efficiency.CO_ 2 saturation point were similar in the 4 chieh-qua cultivars.Yueke No.2 had the highest CO_ 2saturation point,which was lowest in 14-2.There was the highest maximum Pn at saturated-CO_ 2 concentration and carboxylation efficiency(CE)in 14-2,which indicated its higher CO_ 2 utilization efficiency. |
