摘要:

大花海棠‘比哥’系列品种具有较高的观赏和经济价值,其开发前景广阔,但是中国种植的大花海棠‘比哥’系列品种依赖于国外进口。以MS和1/2MS为基本培养基,分别采用不同的植物激素组合,研究组合培养基对大花海棠不定芽分化、不定芽继代增殖和生根的影响,建立大花海棠组培快繁体系,以解决生产上面临的种质资源困境。大花海棠不定芽分化最佳培养基为MS+1 mg/L 6-BA+ 0.1 mg/L 2.4-D+0.2 mg/L NAA,不定芽继代增殖最佳培养基为MS+1 mg/L 6-BA+0.1 mg/L NAA,组培苗生根的最佳培养基为1/2MS+1.0 mg/L NAA。试验建立了一套大花海棠再生体系的完整方案,可为大花海棠的大规模培养、繁殖提供理论依据。

Abstract:

The Begonia benariensis ‘BIG’ has high ornamental and economic value, and has broad application prospects. However, the varieties of B. benariensis ‘BIG’ grown in China rely on foreign imports. MS and 1/2MS were used as basic media, and combined with different plant hormones respectively to study the effects of combination media on adventitious bud differentiation, regeneration and rooting of B. benariensis, so as to establish a rapid propagation system for B. benariensis, and to solve the germplasm resource dilemma in production. The results showed that the optimal medium for adventitious bud differentiation was MS+1 mg/L 6-BA+ 0.1 mg/L 2.4-D+ 0.2 mg/L NAA. The optimal medium for adventitious bud subculture was MS+1 mg/L 6-BA+ 0.1 mg/L NAA. The optimal medium for rooting was 1/2MS+ 1.0 mg/L NAA. The experiment established a tissue culture regeneration system for B. benariensis ‘BIG’, which provided a theoretical basis for large scale culture and propagation.
