马铃薯品种受某种病毒侵染产生退化后,采用茎尖生长点培养方法,可脱去薯块和植株体内的病毒,使其恢复健康而获得高产。这是国内外许多研究单位和生产部门的一条重要经验。目前世界上马铃薯高产国家(如瑞士、荷兰等国平均亩产都在500斤左右)都是由于建立了一套完整的良种繁育体系,生产和使用马铃薯脱毒种薯,从而达到马铃薯稳产高产的目的。我国近十年来在利用茎尖培养脱毒,生产和使用马铃薯脱毒种薯方面也取得了良好的效果。如黑龙江省克
After the potato variety is degenerated by a certain virus infection, the shoot tip growing point culture method can take off the tuberous tubers and the virus in the plant so as to restore the health and obtain the high yield. This is an important experience of many research institutes and production departments at home and abroad. At present, the world’s potato-producing countries (such as Switzerland and the Netherlands have an average yield of 500 kg per mu) are all due to the establishment of a complete breeding system for seed production and use of potato virus-free seed so as to achieve stable and high-yield potato purpose. In the past ten years, our country has also achieved good results in the use of shoot tips for virus-free cultivation, production and use of potato virus-free seed. Such as Heilongjiang Province grams
