马铃薯的退化原因是被病毒侵染所致.病毒侵染植株后通过块茎世代传播,积累,导致产量逐年下降。病毒在马铃薯体内的分布是不均匀的,在生长点的尖端0.1～0.3毫米以内没有病毒或病毒含量很低.在无菌操作条件下,分离培养生长点尖端组织形成完整植株,经病毒鉴定确认无毒,获得无病毒的马铃薯植株和种薯。黑龙江省克山农科所从1973年开始搞这项工作,先后进行了利用生长点组织培养无病毒植
The reason for the degradation of potato is caused by virus infection, which spreads and accumulates through the tubers after it infects plants, resulting in a declining output. The distribution of the virus in the potato body is not uniform, there is no virus or virus content within 0.1-0.3 mm at the tip of the growth point, and under the condition of aseptic operation, a complete plant is isolated and cultured from the growth point and identified by a virus Non-toxic, get virus-free potato plants and seed tubers. Keshan Agricultural University in Heilongjiang Province from 1973 to engage in this work, has carried out the use of growth point tissue culture virus-free plant
