| Abstract: | In this paper the cuttage survival rates and percentage of Class Ⅰ cuttings of the 81 poplar varieties were analyzed systematically with DPS software based on the observation of their growth increments in the seedling stage The results showed that the 81 poplar varieties could be classified into 3 groups, with the 17 varieties in GroupⅡ showing good characteristics. The early growth statistical results of the 17 poplar varieties showed that the vaieties 14,65,41,43,44 and 32 grew better compared with others. |
