摘要/Abstract

摘要： 为探讨不同欧李品种光合能力的差异及其修剪对欧李品种光合作用的影响，以引种的3个欧李品种为材料，以当地野生的欧李生态苗为对照，分别在修剪和未修剪条件下，利用Li-6400 XT便携式光合仪对每个品种在6，7，8，9月的光合生理指标进行了测定。结果显示：未修剪条件下，每个欧李品种在6，7月的净光合速率（Pn）日变化均呈"双峰"曲线，8，9月均呈"单峰"曲线，气孔导度（Gs）、蒸腾速率（Tr）日变化均与净光合速率（Pn）日变化规律基本一致，胞间二氧化碳浓度（Ci）日变化均与净光合速率（Pn）日变化规律基本相反。每月的日均净光合速率（Pn）均表现为：农大7号 > 农大5号 > 生态苗 > 农大6号，农大7号和农大6号之间存在显著差异（P<0.05），4个欧李品种的日均净光合速率（Pn）均表现为：7月 > 6月 > 8月 > 9月。7月修剪的4个欧李品种Pn日变化趋势与未修剪的基本一致，均呈典型的"双峰"曲线，Gs、Ci和Tr日变化曲线也均与未修剪的一致，且峰值均高于未修剪的。除生态苗外，引种的3个欧李品种月均Pn、月均Gs和月均Tr修剪后的显著高于未修剪的（P<0.05）。因此表明，农大5号和农大7号光合性能好，整形修剪有利于欧李光合作用。

Abstract: In order to explore the seasonal changes of photosynthetic capacity, and the influence of prun on different varieties of Cerasus humilis,three introduced cultivars of Cerasus humilis were used as materials and local wild seedlings were used as control.The photosynthetic physiological indexes of four Cerasus humilis varieties under unprun and prun in June, July, August and September were explored using Li-6400 XT portable photosynthesiometer.The results showed that:Under the condition of unprun, the daily changes of net photosynthetic rate(Pn) of the four Cerasus humilis showed ″bimodal″ curves in June and July, and ″unimodal″ curves in August and September.The diurnal changes of stomatal conductance(Gs) and transpiration rate(Tr) were basically consistent with the diurnal changes of net photosynthetic rate(Pn), while the diurnal changes of intercellular carbon dioxide concentration(Ci) were basically opposite to the diurnal changes of net photosynthetic rate(Pn), the average daily photosynthetic rate(Pn) of each month was as follows:Nongda No.7 > Nongda No.5 > Ecological seedling > Nongda No. 6,and Nongda No.7 and Nongda No.6 showed significant difference(P<0.05). The average daily net photosynthetic rate(Pn) of the four Cerasus humilis was as follows:July > June > August > September. In July, the diurnal changes trend of the prun Cerasus humilis varieties were basically consistent with that of the unprun varieties, showing typical "bimodal" curve. The diurnal changes trend of prun Gs, Ci and Tr were consistent with that of the unprun varieties, and the peak value was higher than that of the unprun varieties. Except for the ecological seedlings, the average Pn, Gs and Tr of the other three prun varieties were significantly higher than those unprun(P<0.05). Therefore, the photosynthesis of Nongda No.5 and Nongda No.7 were the best, pruning was conducive to the photosynthesis of Cerasus humilis.
