摘要 以不同品种地被菊的无菌苗叶片为外植体,在附加不同浓度植物生长调节剂NAA和6-BA的MS基本培养基上诱导培养,通过器官直接发生途径获得再生植株。结果表明:不同地被菊品种的叶片外植体再生不定芽的能力差异极大。再生能力强的品种其培养基中生长调节剂配比的浓度也是不同的,‘铺地金’再生的最适宜培养基为MS+6-BA2mg.L-1+NAA1mg.L-1,再生率为96%;‘北林红’再生的最适宜培养基为MS+6-BA1mg.L-1+NAA0.5mg.L-1,再生率为96%。无菌苗继代培养时间对地被菊叶片外植体的形态发生能力有不同的影响,其中‘铺地金’品种高频再生能力保持的时间很长,适合做基因转化的受体系统。
