苎麻是异花授粉作物,种子繁殖容易发生变异,难以保持品种的优良特性;地下茎分蔸繁殖法,又有速度慢、繁殖系数低的缺点。因此,研究既能保持品种纯度和优良特性,又能快速繁殖的方法,是当前苎麻生产上的一个新课题。在前人工作的基础上,我们与上海华东师范大学生物系协作研究的苎麻嫩枝与茎梢带叶水插繁殖法获得成功,报道如下: Ramie is cross-pollinated crops, seed propagation prone to mutation, it is difficult to maintain the excellent characteristics of varieties; underground stems division breeding method, there are slow, low breeding coefficient. Therefore, it is a new topic in current ramie production to study not only the method of maintaining the purity and excellent character of varieties, but also the rapid propagation. Based on the work of predecessors, we succeeded in cooperating with the Department of Biology, Shanghai Huadong Normal University in researching the shoots and shoots of ramie with the leaf water plug propagation method and reported as follows:
