| 摘 要： | 以‘黄河蜜3号’和‘迎春’2个基因型厚皮甜瓜为试验材料,利用CIRAS-2便携式光合仪对2个基因型甜瓜的光合速率日变化及其光合特性对光照强度、CO2浓度和温度的响应进行了研究.结果表明:2个厚皮甜瓜的净光合速率和蒸腾速率日变化为典型的双峰型,有明显的光合“午休”现象,且气孔调节不是甜瓜叶片光合“午休”的主要决定因素.2... |

| Abstract: | Photosynthetic characteristics of two genotype muskmelon(Cucumis melo L.var.cantaloupensis) cv.'Huanghemi No.3' and 'Yingchun' were studied using the CIRAS-2 photosynthetic instrument.The results showed that diurnal changes in net photosynthetic rate(Pn) and transpiration rate(Tr) of two genotype muskmelon leaves were both typical bimodal curves,it showed evidence midday depression which was not determinately regulated by stomata conductance.The responsive curves of photosynthesis of two genotype muskmelon ... |
