摘  要:
各种植物对NaCl都具有一定的敏感性。本实验利用野生型百脉根组织培养再生苗为研究材料,在附加不同浓度NaCl的MS培养基上观察其生长及生根状态,确定百脉根试管苗对NaCl的临界耐受能力,目的是为筛选转耐盐基因百脉根抗盐性植株提供实验依据,同时也可以初步检测所克隆基因的耐盐效果。实验结果:NaCl浓度为0.7%以上的处理,试管苗叶片发白,长势弱,不生根或根停止伸长变褐;NaCl浓度为0.7%(不包括0.7%)以下的处理中,试管苗叶片绿色,长势旺盛,根系较多,与对照(NaCl浓度为0)试管苗状态接近。

摘  要:
Most plants are sensitive to NaCl.In order to identify the NaCl tolerance of Lotus corniculatus L.regenerants in vitro,the growth and rooting of these regenerants cultured in the MS medium supplemented with different concentration NaCl were determined in the experiment.The results showed that plants grew slowly and could not rooting,their leaves turned white when NaCl concentration was above 0.7%.When NaCl concentration was below 0.7%,the plants grew as same as the control.This method could be used in identifying salt tolerance of transgenic plants.
