【摘要】 目的:探索美洲商陆组培快速繁殖技术。方法:以无菌苗作外植体。结果:初代培养的较粗壮茎段为快速繁殖的最佳外植体,初代培养基为MS+NAA0.2 mg/L+6-BA1.0 mg/L;丛生芽最佳增殖培养基为MS+NAA0.2mg/L+6-BA2.0 mg/L,最适生根培养基为1/2MS+NAA0.4 mg/L。结论:采用美洲商陆无菌苗茎段诱导丛生芽可提高繁殖系数,为大量种植提供种苗。更多还原

【Abstract】 Objective: To explore the technique of rapid propagation for Phytolacca americana.Methods:Aseptic seedling were used as explants.Results:The best explants were the stems from strong aseptic seedling.The optimal culture media were MS+NAA(0.2 mg/L)+6-BA(1.0 mg/L)for primarily culture,MS+NAA(0.2 mg/L)+6-BA(2.0 mg/L)for the induction of clustered shoots 1/2MS with NAA 0.4 mg/L for rooting.Conclusion:The propagating coefficient of Phytolacca americana can be improved by inducing the clustered shoots from aseptic seedling.更多还原
