摘　　要：以矮化菊花试管苗为试材,研究了不同激素浓度、不同pH值和不同温度对菊花试管苗生根率、株高和植株粗度的影响。结果表明:温度对矮化菊花试管苗生根率、株高和植株粗度影响最大,IBA浓度对生根影响大于pH,但pH对植株高度和粗度影响大于IBA浓度;在IBA含量为0.4mg/L,pH 6.0的培养基中接种的矮化菊花试管苗,在24℃培养时最适合矮化菊花试管苗生根。Taking dwarf chrysanthemum plantlet as materials,different hormone concentration,different pH values and different temperature on the rooting rate,plant height and panicle neck were studied.The results showed that temperature had a biggest influence on dwarf chrysanthemum rooting rate,plant height and stem diameter,IBA concentration had more influence on the rooting effect than pH;but pH had more influence on plant height and diameter than IBA.When the IBA content was 0.4 mg/L,pH 6.0 medium inoculated dwarf chrysanthemum plantlets in 24℃ culture was the most suitable dwarf chrysanthemum rooting of test-tube seedlings.
