摘要:
通过L16(4 5)正交试验 ,研究最适合青花菜 2周龄下胚轴愈伤组织诱导和不定芽发生的植物生长调节物质的种类和浓度组合。结果发现在NAA、6 BA、TDZ和KT四种激素中 ,NAA对下胚轴愈伤组织发生指数、不定芽发生频率的影响作用最大 ,确定以MS +NAA 0 .2 5mg/L +6 BA 0 .2 5mg/L +TDZ 0 .0 1mg/L(琼脂 0 .8% ,蔗糖 3 % ,pH5 .8)作为单因子试验的培养基。NAA、6 BA和TDZ浓度的单因子试验结果表明最适合下胚轴的培养基配方为 :MS +NAA 0 .1mg/L +6 BA 1 .0mg/L +TDZ 0 .0 6mg/L(琼...
