NaCl胁迫对不同甘薯品种体内离子分配的影响
Effect of NaCl Stress on Ion Distribution in Plants of Different Sweet Potato Varieties
摘要
Abstract
Six sweet potato varieties (J21, JX23, J04150, X26, X27 and X28) were used as the test materials and treated by sodium chloride with the concentration of 0, 0. 2% , 0. 3% and 0. 5% for 100 days. The growth of sweet potatoes was observed and the concentration of Na+ and K * were measured in the roots, stems and leaves. The results showed that under salt stress, the growth of all the tested sweet potatoes, especially X26, was inhibited. The concentration of Na* and the ratio of Na+/K+ in the roots, stems and leaves increased; Na + content was the highest in the roots and the lowest in the leaves. In conclusion, storing most of Na + in roots to reduce its damage to leaves may be an important way for sweet potatoes to endure higher salini-ty.关键词
