| 摘 要： | 研究了ＮａＣｌ对豫棉１５号种子发芽和幼苗生长的影响，结果表明：低浓度的ＮａＣｌ（０．４％以下）能促进种子萌发，而高浓度（〉０．７％）时则显著抑制；无论盐浓度高低，都对棉花幼苗生长产生抑制作用，当ＮａＣｌ浓度超过０．５％时，幼茵的主根长、子叶面积、幼苗干重等均显著低于对照。

| Abstract: | The effects of salt stress on Yumian 15 cotton seeds germination and seedling growth were investigated, The results showed, low NaCl content(<0.4%)could enhance seeds germination, high NaCl content(>0.7%)obviously suppressed seeds germination. However low or high concentraction of NaCl all suppressed cotton seedling growth, when concentraction of NaCl was over 0.5%, the root length, cotyledon area and dry weight of seedling were lower contrast obviously. |
