利用茎尖培养脱毒苗生产无病种薯,是防止马铃薯退化并提高其产量的重要措施.过去通过茎尖培养获得马铃薯脱毒苗,一般需要3年.1985—1986年,我们改进脱毒工作各环节,用一年多时间获得了两个品种的脱毒苗,另有三个品种的培育苗脱去了大部分病毒,1987年又获得了一个品种的脱毒苗.我们先后剥离茎尖3000个,生长点成活率达65%左右,成苗率20%左右.
The use of stem tips to produce virus-free seedlings for the production of disease-free seed tubers is an important measure to prevent potato degradation and increase its yield. In the past, potato virus-free seedlings were obtained through shoot tip culture, which generally took 3 years. From 1985 to 1986, we improved detoxification In all aspects of work, we gained two varieties of virus-free seedlings in more than one year, and another three cultivated seedlings shed most of the virus and obtained a variety of virus-free seedlings in 1987. We stripped the stem tips one after the other 3000, the growth point of survival rate of about 65%, about 20% of seedlings.
