- 摘要:
- 以河南科技学院南瓜课题组培育的“百蜜4号”为试材，以“蜜本南瓜”为对照(CK)，对南瓜田间CO2浓度、光合有效辐射、气温、湿度等气象因子进行了观测，并对南瓜的净光合速率进行平行研究。结果表明：南瓜田间CO2浓度时间变化曲线为U型，变幅为456.9～381.0 mg/kg；南瓜田间光合有效辐射、空气相对湿度和气温时间变化均呈单峰型，最大值分别为1 445.8 μmol?m-2?s-1、61.3%和36.8℃；“百蜜4号”与CK净光合速率呈双峰型，峰值均出现在11:00和16:00，在14:00出现谷值，存在明显的光合“午休”现象。
- Abstract:
- Taking ‘Baimi 4’ pumpkin which cultured by Henan Institute of Science and Technology Pumpkin Research Group as material,and making the ‘Miben’ as the control(CK),CO2 concentration in field,photosynthetically active radiation,humidity,temperature of the weather factors in pumpkin field were measured,and the effect factors of net photosynthetic rate were studied.The results indicated that the filed CO2 concentration presented a U curve and ranged from 456.9～381.0 mg/kg.The maximum value of photosynthetic active radiation was 1 445.8 μmol?m-2?s-1?at 12:00.The air relative humidity was singe-peak and maximum value was 61.3%.The air temperature was singe-peak and maximum value was 36.8 ℃.The net photosynthetic rate of ‘Baimi 4’ and CK presented a double-peak curve,peak value occurred at 11:00 and 16:00,two valley appeared at 14:00 and exited significant photosynthesis ‘noon-rest’.
