利用植物组织培养手段快速繁殖苗木,不仅可解决稀有、名贵品种奇缺的问题,而且为脱毒苗的工厂化生产奠定了基础。但由于试管苗存在着生根难和移栽难等问题,在生产上的应用受到了一定的限制。我们在实践中发现,移栽的试管苗,其原有的根系不仅生长缓慢,而且50％左右不能形成正常的根系。近几年来,我们结合试管苗的繁殖,做了试管苗扦插试验,现将试管苗扦插技术介绍如下:
The rapid propagation of seedlings by means of plant tissue culture can not only solve the problem of scarce rare and valuable varieties, but also lay a foundation for the industrialized production of virus-free seedlings. However, there are some problems such as difficult rooting and difficult transplanting in vitro plantlets, which limits their application in production. In practice, we found that transplanted plantlets, the original root system is not only slow growth, and about 50% can not form a normal root system. In recent years, we combined with the multiplication of test tube seedlings, cuttings test tube seedlings made test tube seedlings now cuttings are introduced as follows:
