| 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MS+6-BA 2.0 mg/L+NAA 0.2 mg/L培养基上的诱导效果较好，分化率达100%；继代培养时，以MS+6-BA 1.0 mg/L+KT 0.5 mg/L+NAA 0.1 mg/L培养基的增殖倍数最高，达11.8倍；再生苗在1/2MS+NAA 0.1 mg/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。 |

| Abstract: |
| 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. |
