摘要
对脱毒甘薯的增产机理进行了研究 ,结果表明 ,甘薯脱毒苗营养生长旺盛 ,主茎长、分枝数、茎叶鲜重等都显著高于普通对照苗 ;脱毒苗薯块膨大早、膨大速度快、产量高。甘薯脱毒后一般可增产 50 %以上 ,出干率提高 1～ 2个百分点。
The mechanism of yield increasing in virus free sweet potato plants was studied under field conditions. The results showed that the virus free plants had obviously higher main stem length, number of branch and fresh weight of stems and leaves than control. Also,the tubers of virus free sweet potato expanded earlier and faster. The yield and dry matter content of virus free sweet potato could increase by over 50% and 1～2 percentage points,respectively.
