摘要/Abstract

摘要： 对带岭试验地25个蒙古栎种源的树高、地径进行调查分析，得到如下结论：（1）蒙古栎1年生苗高、地径及6年生树高、地径间呈正相关且达到了极显著水平。蒙古栎种源各生长性状存在着显著性差异，这表明蒙古栎种源选择是十分必要的。苇河、集安种源可初步作为带岭试验地的优良种源应用于林业生产。（2）蒙古栎地理变异总趋势受经纬度影响，其中经度影响略大。（3）不同蒙古栎种源生长性状、地理、气象因子之间具有一定的相关性。（4）将参试的25个种源划分为3个种源区，Ⅰ区种源多数分布在长白山南部、龙岗山一带，Ⅱ区种源多数分布在长白山及老爷岭，Ⅲ区种源位于小兴安岭和张广才岭。

Abstract: In this study, the heights and diameters of 25 provenances of Quercus mongolica from Dailing sample plots were investigated and analyzed. 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.

Key words: Quercus mongolica, provenance division, geographic variation, fine provenance
