摘要
以3个大豆基因型为材料，以固体培养基中大豆出苗率、苗高和下胚轴长度为指标，研究大豆对NaCl的耐受性。结果表明，大豆不同基因型对NaCl的耐受性不同，东农46对NaCl的耐受性较差。在3个苗期性状中，以苗高和下胚轴长度对NaCl的耐受性较差，当在培养基中加入35～65mmol／LNaCl时大豆的苗高和下胚轴长度的增加受到明显地抑制。
NaCl tolerance was researched by observing emergence rate, seedling height and length of hypocotyl under solid medium with three genotypes in soybean. The results showed that there was a difference in NaCl tolerance among the different genotypes of soybean. Dongnong 46 was weak for NaCl tolerance. Among three characters of seedling stage, seedling height and length of hypocotyl showed to he more sensitive to NaCl. The increase of seedling height and length of hypocotyl was inhibited when the medium was added with 35-65 mmol/L NaCl.
