| 摘 要： | 以西藏半干旱区的两种豆科灌木为研究对象,采用盆栽控水干旱胁迫手段,比较和分析了砂生槐、矮锦鸡儿在持续水分胁迫条件下的生理响应。结果表明：随着干旱胁迫时间推移,土壤含水量不断下降,2种灌木体内水分饱和亏缺值均呈上升趋势,从上升速率和变化情况来看,砂生槐的叶片保水能力优于矮锦鸡儿;叶绿素a＋b值和叶绿素a/b值综合比较结果...

| Abstract: | In this paper,two species of Legume shrubs grow in semi-arid region of Tibet were chosen to research their physiological responses to drought stress through controlling the moisture of soil in pots.Physiological and biochemical characteristics and drought resistance of two shrubs were measured in this experiment.The results showed that,as the time of drought stress prolonged,soil moisture continued to be lower and lower,plant water saturation deficit of all species continued to increase.From the water loss ... |
