木本植物的无性繁殖对于林木育种的发展具有重要意义,因为在这种情况下,后代保持了母本植物的特征和特性。在实践中曾最大限度的推广获得育种营养苗的嫁接方法。然而这种方法具有缺点:时常表现出嫁接成份不能并存而夺去接穗的营养,在砧木影响下改变了接穗的生理过程。培育营养苗的扦插方法能避免这些缺点。无性繁殖的试验工作,证实了 Asexual reproduction of woody plants is of great importance for the development of tree breeding because, in this case, offspring maintain the characteristics and characteristics of the female parent. In practice, it has promoted the grafting method of breeding seedlings to the maximum extent. However, this method has the disadvantage that it often shows that the grafted components can not coexist and take away the nutrition of the scion, which changes the physiological process of the scion under the influence of the rootstock. Cutting methods to nurture seedlings can avoid these drawbacks. Asexual reproduction test work, confirmed
