摘　　要：以苏铁球为试验材料,研究比较了不同浓度NAA、IAA、IBA 3种植物生长调节剂在蘸根处理和浸入生长处理下对苏铁球不定根诱导的影响。结果表明:800mg/L IAA蘸根处理和0.2mg/L NAA浸入生长处理显著促进了苏铁球不定根诱导效果;这2种处理都可用于苏铁水培生产。By root-dipping and root-immersing methods,the effect of different concentration of NAA,IAA and IBA respectively on Cycas revoluta root induction were compared and studied.The results showed that the treatments of root-dipping with 800 mg/L IAA and 0.2 mg/L NAA root-immersing promoted Cycas revoluta root induction significantly,which could be used in Cycas revoluta water culture in practice.
