前言我国利用茎尖组织培养生产的脱毒马铃薯种薯(以下简称脱毒薯),已有效地解决了马铃薯病毒退化问题,使薯块产量有显著提高,一般增产达30％以上,高者成倍增长。鉴于光合作用是作物增产的生理基础,而叶片则是进行光合作用和制造有机物的场所,因此,本文试对脱毒薯和未脱毒薯的植株 Preface China’s use of shoot tips tissue culture to produce virus-free potato seed (hereinafter referred to as drug-free potato), has effectively solved the problem of potato virus degradation, potato tuber yield increased significantly, the general increase of more than 30%, the highest Double the growth. In view of photosynthesis is the physiological basis of crop yield, and leaves is the place for photosynthesis and the manufacture of organic matter, therefore,
