The results showed that: Under salt stress, it was found the content of Na(superscript +), Cl(superscript -), SO(superscript 2- subscript 4) and Na(superscript +)/K(superscript +) ratio in almond rootstocks organs all went up with increased salt stress and longer treatment days, K(superscript +) content changed irregularly. But K(superscript +) content in every organ of A. commans persicoides rootstocks was higher than that of other two almond rootstocks; the ratio of Na(superscript +)/K(superscript +) in Amygdalus communis L. was higher than that of other two rootstocks.

研究结果表明，盐胁迫下，3种砧木根、茎、叶中Na，Cl，SO(上标 2-下标 4)含量及Na/K比均随盐浓度的增加和处理时间的延长而增加，K含量变化规律不稳定，但桃扁桃根、茎和叶片中K略高于其他两个品种；石头扁桃根、茎、叶片中Na/K比值高于其它两个品种，桃扁桃中Na/K比值最低。
