为探讨扁桃幼苗对水分条件的适应能力，以1 a生盆栽扁桃苗为材料，设置5个水平土壤相对含水量处理, 研究了生长状况和主要生理过程对土壤水分胁迫的反应。结果表明,在水分胁迫条件下, 特别是在干旱胁迫下, 苗木生长受到严重抑制, 净光合速率和蒸腾速率降低；随着水分胁迫的加剧，叶片渗透调节和维持膨压能力有一定程度的提高; 过量水分供应，对扁桃生长和生理作用产生不良影响。扁桃幼苗对土壤水分的要求是田间持水量的60%～80%。

With one-year-old amygdulat seedlings as materials, under 5 water stress conditions, the responses of the seedlings to water stress were studied. The results showed that, during water stress, the seedling growth was restrained seriously and photosynthesis decreases significantly, but with strengthening of water stress, the ability of osmotic adjustment of leaf was more improved. Over-water supply was found harmful to the growth and physiological process of amygdulat seedlings. Suitable soil water condition for amygdulat seedlings is 60%～80% of relative soil water content.
