摘　　要：以黄栌的当年生嫩枝茎段为外植体进行簇生芽诱导,对黄栌的快繁技术进行研究。结果表明,诱导簇生芽时,在M S+6-BA 2.0 m g/L+NAA 0.2 m g/L培养基上的诱导效果较好,分化率达100%;继代培养时,以M S+6-BA 1.0 m g/L+KT 0.5 m g/L+NAA 0.1 m g/L培养基的增殖倍数最高,达11.8倍;再生苗在1/2 M S+NAA 0.1 m g/L培养基上生长良好;在炼苗中,移栽基质以蛭石+森林土较好,其有助于小苗的后期生长。It is good to induce cluster shoot of Cotinus coggygria during tenderstem culture by using MS＋6-BA 2.0 mg/L＋NAA 0.2 mg/L,and the differentiation rate of shoot can reach about 100%. The propagation speed is up to 11.8 times that of general in cultivation by using MS＋6-BA 1.0 mg/L＋KT 0. 5 mg/L＋NAA 0. 1 mg/L. The effect of rooting from rebuilded stem is better in 1/2 MS＋NAA 0. 1 mg/L cultivation medium. The vermiculite＋wood soil （1 ： 1） is better transplanting substratum in acclimatization stage ,and it is good for the small seedlings.
