chinois. 以5个初果期花椒品种为研究对象,对其光合指标及相关性进行了研究.结果表明：‘秦安1号’、‘临夏大红袍’的净光合速率和蒸腾速率呈双峰型变化,‘油椒’、‘秦安大红袍’和‘保山小椒’呈单峰型变化;水分利用率日变化平均值大小排序为：‘临夏大红袍’〉‘秦安1号’〉‘油椒’〉‘秦安大红袍’〉‘保山小椒’;净光合速率日变化平均值大小排序为：‘油椒’〉‘秦安1号’〉‘临夏大红袍’〉‘秦安大红袍’〉‘保山小椒’;同时发现影响花椒净光合速率值的主要生态生理指标大小依次为：光合有效辐射〉蒸腾速率〉气孔导度〉胞间CO2浓度.[著者文摘]

The photosynthetic characteristics and their relationship of five cultivars of Zanthoxylum bungeanum in initially fruit time were studied.The results showed that net photosynthetic rate and transpiration rate of the cultivars ＇Qinan No.1＇ and ＇Linxia Dahongpao＇ were changed as bimodal curve,while those of ＇Youjiao＇,＇Qinan Dahongpao＇ and ＇Baoshan Xiaojiao＇ were changed as single peak curve.The order in daily change of average water use efficiency of five cultivars was taken as ＇Linxia Dahongpao＇ ＇Qinan No.1＇＇Youjiao＇＇Qinan Dahongpao＇＇Baoshan Xiaojiao＇,while the order in daily change of average net photosynthetic rate of them was taken as ＇Youjiao＇＇Qinan No.1＇＇Linxia Dahongpao＇＇Qinan Dahongpao＇＇Baoshan Xiaojiao＇.[著者文摘]
