Abstract: The effects of different treatment on root growth potential of Chinese fir (Cunninghamia lanceolata) seedlings after lifting were studied. 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.
