| 摘 要： | 在１５０ｍｍｏｌ／ＬＮａＣｌ胁迫下，长穗偃麦草（Ａｇｒｏｐｙｒｏｎｅｌｏｎｇａｔｕｍ，２ｎ＝７０）４Ｅ染色体代换普通小麦４Ｄ染色体后能显著降低胁迫下植株上部的Ｎａ离子含量而维持较高水平的Ｋ离子含量。

| Abstract: | Under 150 mmol/L NaCl stress,higher K and lower Na ion contents in shoots of 4E(4D) substitution line,of which 4D chromosome is substituted by 4E chromosome from Agropyron elongatum (2n=70),are kept than those in common wheat.Thus 4E chromosome carries the gene of K/Na discrimination character,and the gene is stronger in salt tolerance than that on 4D chromosome from common wheat. |
