| 摘 要： | [目的]研究两个耐盐性不同的荞麦品种体内Na^＋分配与其耐盐性的关系。[方法]测定两个荞麦品种玲0808（盐敏感）和川养1号（耐盐）幼苗根部、茎基部和叶片Na^＋含量。[结果]盐胁迫下，耐盐荞麦品种体内Na^＋主要在根部和茎基部累积，盐敏感荞麦品种体内Na^＋主要积累在根部。[结论]耐盐荞麦品种的限Na^＋能力大于盐敏感荞麦品种，耐盐荞麦品种叶片Na^＋含量较低，更耐盐。

| Abstract: | [Objective] This research aimed to discuss the correlation between Na+ distribution in two buckwheat varieties with different salt tolerance.[Method] Na+ content in the seedling root,stem base and leaf of two buckwheat varieties including TQ-0808(salt-sensitive)and Chuanqiao No.1(salt-tolerant)were determined.[Result]Salt-tolerant buckwheat variety accumulated more Na+ in the root and stem base,while salt-sensitive one accumulated more Na+ in the root.[Conclusion] Na+ restriction capability of salt-tolerant... |
