The results of route survey on growth performance of wild Acer griseum showed that the average DBH was 13.6 cm, ranging from 3.5 cm to 45.1 cm, the ground diameter ranged from 11.8 cm to 63.0 cm and the tree height ranged from 2.0 m to 25.0 m. According to the maximum values of DBH and ground diameter of individuals, the 11 populations were divided into three groups according to their distribution: the central group, the transitional group and the marginal group. The central group consisted of the populations from Chengkou of Chongqing and Xingshan of Hubei province, with the maximum DBH larger than 40.0 cm. The transitional group were composed of the populations from Shennongjia of Hubei Province, Taibai Mountain of Shaanxi Province, Neixiang and Laojun Mountain of He'nan Province, with the maximum DBH from 28.0 cm to 40.0 cm and the maximum ground diameter was 60.0 cm. The marginal group included the populations from Wufeng of Hubei Province, Yangcheng of Shaanxi Province, Yuanling of Hu'nan Province, Xixia of He'nan Province and Xiaolong Mountain of Gansu Province, with the maximum diameter smaller than 20.0 cm and the maximum ground diameter ranging from 24.0 to 44.0 cm.
