苎麻是我国的特产和重要纺织纤维作物。当前苎麻的优良品种多属自然杂种一代,用种子繁殖易发生性状分离,影响纤维的产量和品质。因此在生产上,都用无性繁殖保持品种的纯度和特性,由于繁殖系数太低,不能满足良种迅速扩大种植的需要。我们研究的组织培养法快速繁殖苎麻良种的技术,已应用于生产,但此项技术在实际应用中尚存在一些急待改进的方面。近几年来,我们围绕简化方法,降低成本等方面进行了研究,使苎麻微繁殖技术的操作程序更加完善和实用。 Ramie is a specialty of our country and an important textile fiber crop. Most of the current ramie hybrid varieties are natural hybrids, easy to breed with seed separation, affecting fiber yield and quality. Therefore, in production, the purity and characteristics of the cultivars are maintained by asexual reproduction. Due to the low reproductive coefficient, it can not meet the needs of the rapidly expanding planting of the elite. The technique of tissue culture that we studied to breed ramie seeds quickly has been applied to the production. However, there are still some urgent aspects to be improved in the practical application of this technique. In recent years, we have conducted researches on simplifying methods and reducing costs, which have made the operation procedure of ramie micropropagation technology more perfect and practical.
