| 摘 要： | 对短穗柽柳幼苗的水分状况进行了研究。幼苗自５月下旬萌发至９月份，其水势逐渐降低，由－０．７５ＭＰａ降至－２．４７Ｍｐａ，保水力逐渐增强，幼苗表现出较强的蒸腾调节能力。试验结果还表明，至７月份，幼苗已具有较强的抗旱生理适应性，这使幼苗顺利度过７月底至８月初的干旱炎热时期而存活。

| Abstract: | A systematic study on the water status about the seedling of Tamarix laxa was made.The result showed:the seedling possessed distinct ability to adjust its transpiration;there was a marked drop in water potential and a strengthening in water holding capacity.Up to July,the drought resistance physiology of the seedling could grow normally in desert when the habitat became dry. |
