NaCl对吸胀后小麦种子发芽和幼苗生长的影响

Effect of NaCl on Inhibed Seed Germination and Seedings Growth of Different Cultivars of Wheat

用不同浓度的Nacl处理 4个品种小麦吸胀后的种子 ,2 0 0 - 2 5 0mmol/LNacl胁迫下 ,4个品种的发芽率明显降低 ,但品种间的耐盐能力有异 ,低盐浓度下 ,根比地上部对盐害更为敏感 ,高盐浓度下 。

Four kinds inbibed wheat seeds are treated with nacl that are different density,With the force of NaCl(200～250mmol/L),the germination Percentage of these four kinds seeds reduce clearly,But among the kinds the Seeds Salt resisting qualities ere different Under the low salt density condition,the root is highly sensitive to salt harm than the part above ground,Under the high Salt donsity condition,that is contrary.
