| Abstract: | Growth potential of Chinese chestnut seedlings in stem diameter and tree highness are stronger on the third year after the planting than of the grafting trees. Chestnut seedlings from the county Yongren grew the fastest in stem diameter, tree highness and tree crown. The precocity of the Chinese chestnut only showed in formation of male flower and pistil. Chestnut seedlings from the county Yongren bore the most at the average of 104.6 cupules on fourth year after planting, but all were empty burs. |
