| 摘 要： | 对意大利杨，群众杨和胡杨分别进行了盐分处理，处理后的第１周发现不同处理对钠Ｎａ＾＋和Ｃｌ＾－的吸收有显著的影响，意大利杨和群众杨对盐分离子的吸收随盐分处理浓度的升高而升高，而胡杨却不是这样，相对其它两种杨树而言，胡杨较低的盐分吸收很可能是由于其离子选择能力较高所造成的。

| Abstract: | Three poplar genotypes: P italica,P popularis and P euphratica were subjected to salt stresses Significant differences between salt treatments were apparent by the first week for both Na and Cl - uptake For both P italica and P popularis,the uptake of Na and Cl - increased with increasing salt treatments,however this was not apparent in P euphratica The lower uptake of salt ions compared with the other genotypes was most likely due to ion selection in P euphratica |
