为探讨不同种源在辽东山区的生长表现，对17个产地红松子代在辽宁省草河口镇的苗期生长性状进行调查分析，结果表明，红松苗高和地径的生长在产地间的差异达到极显著水平，辽宁地区种源普遍优于吉林、黑龙江地区种源；红松苗期生长性状的基本变异模式是海拔垂直梯度为主，纬向渐变为辅的连续型变异。

Based on growth character ofPinus koraiensis seedings from 17 sources, the following conclusion was obtained. Height and diameter growth of Pinus koraiensis seedling from different sources reached a significant level. The sources of Liaoning region was better than that of Jilin and Heilongjiang region. The basic variation pattern of Pinus koraiensis seedling growth character was continuous variation, with vertical gradient of elevation was given priority to zonal gradient
