摘  要:
[目的]为驱蚊香草组织培养中试管苗的不定根诱导提供参考。[方法]将驱蚊香草无菌苗分别置于添加不同浓度NAA、IAA、IBA、PP333的MS基本培养基中诱导生根,研究其生根状况。[结果]浓度0.05~1.00mg/LNAA、IBA、IAA、PP333均能诱导驱蚊香草试管苗生根且生根率达100%,但对试管苗平均根长、平均根数、含水量及苗高的影响有明显差异。[结论]0.10mg/LIAA和0.10mg/LPP333为驱蚊香草试管苗的最佳生根试验浓度。

摘  要:
[Objective]This study provided reference for rooting in vitro of Pelargonium gravelens. [Method]The regenerated shoots were cultured on MS medium with different concentrations of NAA,IAA,IBA and PP333. [Results]The same rooting rate reached 100 percent based on all of the concentrations from 0. 05 mg/L to 0. 10 mg/L of NAA,IAA,IBA and PP333,but there were many differences in average root length,average root number,water content and seedling height. [Conclusion]The best medium to the root induction of Pelargonium graveolen were 0. 10 mg/L IAA and 0. 10 mg/L PP333.
