| 摘 要： | 研究了褐藻酸钠对向日葵幼苗遭受盐胁迫的缓解作用。结果表明:在6 g/L的氯化钠胁迫下,加入0.5 g/L褐藻酸钠后,向日葵幼苗的存活率提高了69.1%,株重增加了54.7%,叶绿素含量提高了47.6%,根数增加了55.6%,根长增加了30.8%,SOD活性增强了50.2%;褐藻酸钠可提高向日葵幼苗的耐盐适应性,缓解氯化钠胁迫造成的伤害。

| Abstract: | The effect of sodium alginate on H.annuus L.seedlings to salt-tolerance was studied.The results showed thatafter seeding of H.annuus L.were dealt with by NaCl concentration at 6 g/L,adding sodium alginate concentration at 0.5 g/L.The H.annuus L.seeding survival rate had increased by 69.1%,the seeding weight by 54.7%,the chlorophyll content increased by 47.6%,the number of root had increased by 55.6%,the length of root increased 30.8%,SOD activity increased by 50.2%.In a word,sodium alginate could increase a... |
