摘要

为研究梵净山石斛快速繁殖技术,对其保育提供基础资料,本实验分别以梵净山石斛茎段、种子为外植体进行组培快速繁殖技术研究.结果表明,以茎段为外植体,最佳消毒方法为:75%乙醇消毒30 s,0.1%HgCl2消毒13 min,腋芽诱导最佳组合为:1/2 MS/B5+0.5 mg/L 6-BA+0.2 mg/L NAA,不定芽诱导和增殖最佳组合为:1/2 MS+0.5 mg/L NAA+1 mg/L 6-BA,以种子为外植体,种子萌发和原球茎诱导最佳组合为:MS+1.0 mg/L NAA+1.0 mg/L 6-BA+1 g/L活性炭,原球茎增殖最佳组合为:MS+0.5 mg/L NAA+2 mg/L 6-BA,无菌小苗增殖最佳为:MS+0.5 mg/L NAA+1.0/2.0/3.0 mg/L 6-BA.生根壮苗最佳组合为:MS+0.5 mg/L NAA+1/0.1/0.5 mg/L IBA.

Abstract

In order to study the rapid propagation technology of Dendrobium fanjingshanensis and pro-vide basic data for its conservation,the stem segment and seed of Dendrobium fanjingshanensis were used as explants to study the rapid propagation technology of tissue culture.The results showed that:with stem segment as explants,the best disinfection methods were:75%ethanol disinfection for 30 s,0.1%HgCl2 disinfection for 13 minutes,and the best combination of axillar bud induction was:1/2 MS/B5+0.5 mg/L 6-BA+0.2 mg/L NAA,the optimal combination of adventitive bud induction and proliferation was:1/2 MS+0.5 mg/L NAA+1 mg/L 6-BA,with seeds as explants,the optimal combination of seed germination and procorm induction was:MS+1.0 mg/L NAA+1.0 mg/L 6-BA+1 g/L activated carbon,and the optimal combination of procorm proliferation was:MS+0.5 mg/L NAA+2 mg/L 6-BA,the optimal proliferation of sterile seedlings was MS+1.0 mg/L NAA+1.0/2.0/3.0 mg/L 6-BA.The best combination of rooting and strong seedlings was MS+0.5 mg/L NAA+1/0.1/0.5 mg/L IBA.
