摘要
榛子是一种无性繁殖相对困难的树种,目前主要采用压条法进行繁殖,繁殖系数低,这限制了榛子苗的大量生产。为了加快榛子苗木繁殖的速度,综述了有关榛子压条、扦插、嫁接和组织培养等方面研究的现状与趋势,分析了相关研究中存在的问题,并指出了其发展方向。认为如何有效地提高榛子的繁殖系数,是榛子繁殖亟待解决的问题;繁殖速度快的扦插、组织培养等繁殖方法将成为解决榛子繁殖难题的有效途径。
Corylus heterophylla vegetative propagation was relatively difficult, layering method was mainly used at present, but low coefficient of propagation limited mass production of its seedlings. In order to accelerate propagation of Corylus heterophylla, status and trends in study of layering, cutting, grafting and tissue culture were reviewed, problems existed in related research were analyzed and future direction of development was also pointed out. It is suggested that how to increase propagation coefficient effectively is an urgent task; cutting, tissue culture and other methods which propagate fast are effective ways in Corylus heterophylla propagation.
