为了解决洋芋病毒退化问题,从一九七七年开始,我们承担了省列洋芋茎尖培养试验研究课题。现将两年来的试验工作总结如下。一、基本情况: 植物组织培养是本世纪才开始的一项先进科学技术。洋芋茎尖培养,系根据病毒在植物体内不均衡,越是接近生长点的顶端病毒越小,在顶端分生组织中很少或没有病毒存在这一特 In order to solve the problem of potato virus degeneration, starting from 1977, we undertook the provincial pilot project on the cultivation of potato leaf tips. Now two years of experimental work is summarized as follows. First, the basic situation: Plant tissue culture is the beginning of this century, an advanced science and technology. Potato shoot culture, based on the virus in the plant is not balanced, the closer to the growing point of the top of the virus is smaller, in the apical meristem little or no virus is present
