The conclusions were as follows: (1) There were significantly positive correlations in height and diameter between 1-year and 6-year Q.mongolica seedlings, respectively. The growth characteristics from 25 provenances of Q.mongolica were significantly different, indictated that it is important to carry out provenance selection for Q.mongolica. Therefore, it was initially stated that Weihe and Jian were excellent seed resources in Dailing sample plots for forestry production. (2) The main trend of geographical differentiation was controlled by both latitude and longitude, while latitude influenced more. (3) There were certain correlations among growth characteristics and geographical climatic factors of Q.mongolica provenances. (4) 25 provenances were divided into 3 provenance areas. The first area was mainly located in Longgang hill and the south of the Changbai hill. The second one is mostly in Changbai hill and Laoyeling. The majority of the third one was located in Xiaoxing’anling and Zhangguangcailing. %U https://bbr.nefu.edu.cn/EN/10.7525/j.issn.1673-5102.2013.02.008
