五个桑树品种不同部位叶片含水量的测定

Measuring Water Content in Leaves at Different Positions of Five Varieties of Mulberries

选择冀桑2号、鲁插1号、坎下白、桲椤和湖桑32号,测定这5个桑树品种的叶片绝对含水量和鲜重含水量。结果表明,冀桑2号、坎下白和湖桑32号的叶片鲜重及干重在第十八位叶达到最大值,鲁插1号和桲椤在第十一位叶达到最大值;而5个桑树品种的叶片绝对含水量和鲜重含水量均在第四位叶达到最大值。

The mulberry leaves at the 4th ,7th ,11th ,15th ,18th ,22th ,26th leaf positions of Jisang 2 , Lucha 1 , Kanxiabai ,Boluo and Husang 32 were collected to measure fresh weight and dry weight ,calculating and analyzing the ab‐solute water content and water content of fresh weight of leaves .The results showed that fresh weight and dry weight of leaves both maximized at the 18th leaf position of Jisang 2 ,Kanxiabai and Husang 32 ,but at the 11th leaf position of Lucha 1 and Boluo .The absolute water content and water content of fresh weight of leaves at the 4th leaf position of five varieties of mulberries all maximized .
