| Abstract: | Compared with control, accumulation of dry matter of virus free sweetpotato cuttings was evidently improved in growth and development period. Its law of distribution showed that dry matter was distributed to vines mainly in early stage and to storage root speedily in middle and later stages. Biological yield of vine tip cutting, original cuttings,stock cuttings and improved variety cuttings of virus free sweetpotato Xushu 18 was higher than control, increasing by 54.7 %, 32.3 %, 27.9 % and 14.1 % respectively and economic yield raised by 53.6 %, 23.9 %, 22.0% and 12.4 % respectively, and had harmonious source sink relationship. |
