The results showed that:(1)Pruning leaf and root significantly affects root growth potential of Chinese fir seedlings. The root growth potential will decrease with the increase of pruning intensity. (2)The loss of water will reduce the root growth potential. (3)Root growth potential is not closely correlated with seedling morphological indexes.展开更多
The length, diameter, shape coefficient of fruit, the fresh weight, length, diameter, shape coefficient, weight of seed and pulp production ratio from 6 sources of Macrocarpium officinalis (Sieb. et Zucc.) Nakai were ...The length, diameter, shape coefficient of fruit, the fresh weight, length, diameter, shape coefficient, weight of seed and pulp production ratio from 6 sources of Macrocarpium officinalis (Sieb. et Zucc.) Nakai were analyzed. For all 9 characters, there were no significant differences existed within mother trees, however, there were significant differences existed among sources and trees with the coefficients of variation vary from 13.39% to 36.43%. The order of the variation degree is among sources>among mother trees>within mother trees. Drupe size and shape were closely related with those of seed, but the pulp production ratio was not related with other characters.展开更多
