近年,植物病毒病危害增加,种类增多,严重地影响农业生产和植物栽培。为了解决病毒污染问题,有些国家研究并应用植物生长点培养法。薯类以及用接穗、插条和分株等无性繁殖方法的植物,通过培养生长点,可以得到无病毒的植株。在精心管理下,避免再度感染病毒,无毒病株可作原种用。美国人1948年从
In recent years, the increased risk of plant virus diseases and the increase of species have seriously affected agricultural production and plant cultivation. In order to solve the problem of virus contamination, some countries study and apply plant growth point culture method. Potato, as well as plants that use asexual propagation methods such as scions, cuttings, and ramets, can grow virus-free plants by growing growing points. Under careful management, to avoid re-infection of the virus, non-toxic strains can be used as the original species. Americans from 1948
