利用茎尖组织培养生产脱毒0．6-12克马铃薯微型脱毒原原种，虽可周年进行工厂化生产，明显提高产量和经济效益，但因生产出的微型脱毒原原种存在薯休眠期过长（一般比大田生产的种薯长一倍以上），靠自然打破休眠期不能按期投入使用等问题，以致制约了其应用推广速度。几年来， The use of tip tissue culture to produce virus-free detoxification 0.6-12 grams of micro-detoxification of the original potato, although the anniversary of the factory production, significantly improve yield and economic benefits, but because of the production of micro-detoxification of the original stock of potato Excessive dormancy period (generally more than twice as long as the field-produced seed potato), and naturally restless dormant period can not be put into operation on schedule, which has restricted the application of the promotion speed. In recent years,
