摘　　要：欧李为1种新兴果树,经济价值很高。利用便携式LI-6400XT光合仪对4个欧李品种在6~9月份的光合生理日进程进行了测定,同时对叶面积、果实大小和产量也进行了测定。结果表明:农大5、农大7号产量较高,可以在与民勤相似气候类型的干旱荒漠区生产中推广应用,以农大5号为优,栽植3 a平均单株产量1.29 kg;生态早熟种对于干旱荒漠气候适应性较强,产量较低,可以适当用于生态化栽培生产;4个欧李品种在7月份净光合速率最高,但光合午休现象比较明显;8月份,4个欧李品种的净光合速率、蒸腾速率、气孔导度和胞间二氧化碳浓度日变化表现出比较明显的品种特性。Cerasus humilis is a new fruit tree with high economic value.The diurnal course of photosynthesis,leaf area,fruit size and yield of four Cerasus humilis cultivars from June to September were measured by portable LI-6400XT to study variety differences.The results showed that Nongda No.5 and Nongda No.7 had higher yields and could be popularized and applied in the production in arid desert areas with similar climatic types as Minqin.Nongda No.5 was the best,and the average yield per plant of 3 a was 1.29 kg.Ecologically precocious species have better adaptability to arid desert climate and lower yield,which can be used for ecologically cultivated production.The net photosynthetic rate of the four prunus species was the highest in July,but the phenomenon of siesta was obvious.In August,the net photosynthetic rate,transpiration rate,stomatal conductance and diurnal variation of intercellular carbon dioxide concentration of the four Cerasus humilis showed obvious variety characteristics.
