| Abstract: | Compared with the control,accumulation of dry matter of virus free sweet potato Beijing 553 was evidently improved in all stages of growth and development.Its law of distribution showed that dry matter was distributed mainly to vines and leaves in the early siage and to storage root speedily in the middle and later stages.It had harmonious source sink relationship.Biological yield of vine tip cutting,original cutting and stock cutting of virus free Sweet potato Beijing 553 was higher than that of the control,increased by 51.3%,45.7% and 22.7% respectively,and the economic yield was raised by 63.3%,54.6% and 23.7% respectively,and the economic coefficient was significantly higher thah that of the control. |
