摘要
本文对吉林省蒙古栎种群的生长状况进行了调查与分析。结果表明:不同地理种群间的树高、胸径差异均达到极显著(P<0.01)。聚类分析表明,蒙古栎可划分为3类种群,其中,种群1和种群3为速生优良种群。经计算,确定了蒙古栎的选优标准:树高≥18.45 m、胸径≥39.114 cm,形质指标综合分值≥8.0。
The growth of Quercus mongolica populations was investigated and analyzed in this study.The results showed that the tree height and diameter at breast height(DBH)reached a significant level among different provenance(P<0.01).The cluster analysis revealed that Quercus mongolica populations could be divided into three types,and cluster 1 and cluster 3 were the fast-growing quality populations.Through calculation,the optimal selection criteria of Quercus mongolica were determined as follows,tree height≥18.45 m,DBH≥39.114 cm,comprehensive score of shape and quality indexes≥8.0.
