不同桑树品种水分生理特性的研究

Study on the Characteristics of Water Physiology of Different Varieties of Mulberry

通过对农桑 12号、湖桑 32号、选 792、新一之 4个不同桑树品种的叶水势、气孔导度、蒸腾速率等系列水分生理指标的分析 ,比较出 4个品种叶水势、气孔导度、蒸腾速率的大小顺序均为农桑 12号 <选 792 <湖桑 32号 <新一之。表明农桑 12号、选 792对水分利用率高 ,湖桑 32号。

Different mulberry varieties were used as experimental materials to analyse the leaf water potential,transpiration rate and stomatal conductance.The order of them is Nongsang 12<Xuan 792<Husang 32<Shinichinose.The results showed that the water use of Nongsang 12,Xuan 792 is very effcient,that the requirement on water of Husang 32,Shinichinose is high.
