摘    要:研究了NaCl和Na2SO4不同浓度下两种中性盐胁迫对乌拉尔甘草种子萌发的效应。结果表明:280mmol/L浓度的NaCl和Na2SO4处理时,发芽率高于60%,高浓度的Na2SO4抑制种子发芽强于NaCl;不同浓度Na2SO4处理的发芽高峰期出现比对照早3~5d,比NaCl处理的早2~6d;Na2SO4处理种子的发芽势小于相同浓度的NaCl;溶液浓度大于200mmol/L时,种子发芽指数小于对照,NaCl溶液各梯度处理下的发芽指数均高于相应浓度的Na2SO4。发芽率、发芽势和发芽指数与NaCl和Na2SO4浓度之间呈极显著的负相关,发芽高峰期的出现与NaCl浓度之间呈正相关,与Na2SO4浓度之间呈负相关。

关 键 词:中性盐胁迫  甘草  种子萌发

Abstract:Two kinds of neutral salt stress on seed germination effects of Glycyrrhiza uralensis were analysed in this study.The results showed that the germination rate was higher than 60% at the 280 mmol /L concentrations of NaCl and Na2SO4.High concentrations of Na2SO4 had stronger inhibition to seed germination than that of NaCl.The germination peak value were earlier 3 to 5 days than that of ck treated with different concentrations of Na2SO4,and earlier 2 to 6 days than that of treated with NaCl.Seed germination ...
Keywords:neutral salt-stress  licorice  germination
