- 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0.4 mg/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。
- Abstract:
- 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.
