橡皮树(Ficus elastica Roxb.)在生产上多采用扦插繁殖,但此法与试管繁殖相比繁殖系数低,且受母本及季节的限制。我们用从南方引进的黑金刚橡皮树的优良品种为材料,对其茎段进行离体快速繁殖,取得了较好成绩,并在规模化生产、批量化繁殖上获得良好的收益。对解决北方地区大量从南方地区高成本引种的状况及北方地区母本少、繁殖系数低的现状有一定帮助。一、材料与方法1、外植体处理从温室内培养的生长健壮的黑金刚橡皮树植株上剪取2～5厘米的嫩梢,用洗衣粉刷洗表面、自来水冲洗
The production of Ficus elastica Roxb. Is more cuttings, but this method has a lower reproductive coefficient compared with that of the test tube and is limited by the mother and the season. We use the fine varieties of black walnut introduced from the south as the material, rapid propagation of its stems in vitro, and achieved good results, and in large-scale production, batch breeding gain a good return. This will help to solve the problem of large numbers of high-cost introductions from northern areas in the north and less maternal and northern multiples in northern areas. First, the material and methods 1, explant processing from the greenhouse cultivation of robust black walnut rubber plant cut 2 to 5 cm of young shoots, scrub the surface with detergent, tap water rinse
