| 摘 要： | 耐盐牧草有选择性吸收Ｋ＋的能力，通过比较在相同盐份中生长的不同牧草种的叶片Ｋ＋／Ｎａ＋，可鉴定出种间耐盐性，Ｋ＋／Ｎａ＋值大的材料耐盐性强。

| 关 键 词： | 牧草 K~＋／Na~＋ 耐盐性 |
The Interrelation of K+/Na+ Content with Salt Tolerance of Grass Species in the Gramineae Family |
| |
| Abstract: | The Salt tolerance in grasses is liable to have some certain selectivities to absorb K+ and meanwhile,through compaing with the K+/Na+ of leaf lamina of various grasses grown on soils that having the same salt contents,the tolerance in themselves can be identified in various grass species.Those species that having higher K+/Na+ rate were evaluated to possess also much more persistent variablility in salt tolerance. |
