| Abstract: | The dry matter production property of virus free sweet potato cutting of Beijing 553 was analyzed by using growth analysis. The LAI, RGR, NAR and dry matter accumulation of vine-tip cutting, original cutting and stock cutting of virus free sweet potato Beijing 553 was higher than CK, LAR was lower. The results showed that virus free sweet potato had better dry matter production property, and could be used commonly in sweet potato production. |
