盐胁迫对野生稻种子萌发及幼苗生长的影响
Effects of Salt Stress on Seed Germination and Seedling Growth of Different Wild Rice
摘要
Abstract
The effects of different concentrations of NaCl on seed germination and seedling growth of wild rice were studied with 3 wild rice varieties(series) and conventional rice variety Jigeng 301(CK). The results showed that the effects of low concentration of salt stress on seed germination and seedling growth of wild rice and conventional japonica rice was different. When the concentration of NaCl≤0.3%, the effects of salt stress on seed germination and seedling growth of wild rice were little, but it improved the seed ger-mination and seedling growth of Jigeng 301;when the concentration of NaCl≥0.5%, with the increase of NaCl concentration, the ger-mination rate, length of root, the height of seedling, root/shoot ratio of wild rice were decreased; the concentration of NaCl had a neg-ative correlation with the germination rate of wild rice; the inhibitory effect of NaCl on the root of wild rice seedling was stronger than that of seedlings; different wild rice varieties had different tolerance to NaCl solution, from big to small, which is MY-3, Yanyinhong, HY-1.关键词
