嫩枝扦插作为一项简单、实用的繁殖方法,不仅保持了母本的优良遗传性状,而且是脱毒苗培育的一种途径。在扦插中进行生长素浸渍处理,可提高成活率、缩短成苗时间。常用的生长素有IBA、NAA及IAA,其中IBA效果最好。不过IBA低浓度长时间处理易引起嫩枝失水,使成活率降低,故多数以高
Softwood cutting as a simple and practical method of reproduction, not only to maintain the excellent genetic characteristics of the female parent, but also a way to cultivate virus-free seedlings. In the cuttings for auxin impregnation treatment, can improve the survival rate, shorten the time for seedlings. Common auxins are IBA, NAA and IAA, of which IBA works best. However, low concentrations of IBA for a long time can easily lead to water loss of young shoots, so that the survival rate decreased, so the majority of high
