玉簪新品种无性快繁研究

Study on Rapid Propagation of Newly Introduced Hosta Plantaginea Varieties

以玉簪新品种的幼芽为外植体进行无性快繁试验,结果表明:适宜的启动培养基为MS+6-BA3.0+2,4-D1.0(mg/L),该培养基有很好的诱导外植体产生不定芽苗的效果;适宜的增殖培养基为:MS+6-BA1.0+NAA0.1(mg/L),形成的丛生苗比较健壮;生根时MS培养基较为合适。

The rapid propagation of newly introduced Hosta plantaginea varieties were studied by means of tissue culture. The results showed that introduction medium with MS＋6-BA3.0＋2,4-D1.0（mg/L） was suitable, had good induced effect to explantation growth out adventitious bud; and subculture medium with MS＋6-BA1.0＋NAA0.1（mg/L） was the optimum medium, formed tufted seedling is more healthy with this medium; the appropriate rooting medium was MS.
