通过组织培养方法,快速繁殖木本植物是为种草种树提供大量优质苗木的一个重要途径,尤其是繁殖优良树种和难繁珍贵树种的捷径。用组织培养的手段繁殖木本植物的方法有短枝扦插、器官发生和胚状体发生等途径。本文快速繁殖难繁树种—河北杨微型繁殖即无菌短枝扦插的方法与概况作了简单的介绍,其特点是繁殖速度较常规无性繁殖快,并可用于繁殖或保存以繁殖的优良珍贵树种,这在果树和林木生产上很有应用价值,是加速我省种草种树,治穷致富的具体措施之一。
The rapid propagation of woody plants through tissue culture is an important way to provide a large number of high-quality seedlings for the planting of seed trees and grass grasses. In particular, it is a shortcut to breed fine tree species and hard-to-reach rare species. Methods of tissue culture propagation of woody plants are short cuttings, organogenesis and embryogenesis and other means. In this paper, the rapid propagation of difficult tree species - Hebei Yang micro-propagation of sterile spur cuttings methods and overview made a brief introduction, which is characterized by faster propagation than conventional cloning, and can be used for reproduction or preservation to breed fine precious species , Which is very useful in the production of fruit trees and trees. It is one of the specific measures to speed up the planting of trees and grass in our province and get rich and poor.
