| Abstract: | The photosynthetic characteristics of potato leaves were studied using portable LI 6400 photosynthesis measurer. The results showed that the photosynthetic rates of virus free potato leaves were higher than that of check by 10.05 % and 12.82 % in seasonal and diurnal change, respectively. The changes of SLW and LAI of virus free treatment were higher than check by 32.51 % and 68.0 %, respectively. Therefore, virus free potato has a higher energy utilization efficiency and more accumulated photosynthate which are of benefit to high yield. |
