摘要: 为了建立果桑组织培养快繁技术体系,以白玉王品种当年生带腋芽茎段为外植体,研究不同植物生长调节剂及其不同浓度配比对果桑组织培养苗生长的影响,筛选出最适的腋芽诱导、增殖和生根培养基。结果表明:外植体灭菌消毒方法为75%乙醇+灭菌30 s+0.1% HgCl2+浸泡10 min;最适的腋芽诱导培养基为MS+2.0 mg/L 6-BA+1.5 mg/L IBA;增殖培养基为MS+2.5 mg/L 6-BA+0.5 mg/L IBA;生根培养基为 1/2MS+0.5 mg/L NAA。该研究为果桑白玉王进行工厂化育苗提供了研究基础。

Abstract: In order to establish the tissue culture system of rapid propagation of fruit mulberry,the effects of different plant growth regulators and different concentration ratios on the growth of fruit mulberry tissue culture seedlings were studied by taking the variety of Baiyuwang stem segment with axillary bud as explants,and the optimum axillary bud induction,proliferation and rooting medium was selected.The results showed that the sterilization method of explants was 75% ethanol+sterilization 30 s+0.1% HgCl2+immersion for 10 min.The optimal medium for axillary bud induction was MS+2.0 mg/L 6-BA+1.5 mg/L IBA.The culture medium was MS+2.5 mg/L 6-BA+0.5 mg/L IBA.The rooting medium was 1/2 ms+0.5 mg/L NAA.It provides the research foundation for the fruit mulberry Baiyuwang seedling in the factory.

Key words: Fruit mulberry, Tissue culture, Axillary bud stem section
