【Abstract】 The paper studied effects of viruses-free technique on development and growth of sweet potato. The results are as follows: 1. Virus-free sweet potatoes have high photosynthesis and can accumulate more photosynthates; 2. During late growing period, virus-free sweet potatoes had thick vine with good transport system, reasonable T/R value, early root filling, and high percentage of success in large and middle-size potato; 3. Virus-free potatoes have potentiality of yield.更多还原
