The afforestation of Pinus koraiensis under canopy is an important management method to promote the transformation of natural secondary forest to broad-leaved Korean pine forest. For different tree species and composition ratio, the forest afforestation environment is very different in the diverse types of natural secondary forest. However, there was no research on the improvement of P. koraiensis varieties in Korean pine afforestation under canopy of natural secondary forest. In view of problems above, the provenance test of Korean pine was performed in different types of natural secondary forests, such as mixed forests, Poplar-brich forests, and hardwood forests, in Lilin experimental forest station of Xiaoxing’an mountains. The results showed that there were significant or extremely significant differences in diameter above ground, height, 7-year high growth, one-year high growth, and conservation rate of Korean pine provenances among different types of natural secondary forests; the Poplar-brich forests exhibited the best performances of Korean pine afforestation under canopy, followed by hard broad forest hardwood forests by turn; the Tieli was the superior provenance for afforestation in Poplar-brich forests and mixed forests, while the Wangqing provenance showed the best performance in the excellent provenance in hardwood forests.

Key words: Xiaoxing’an Mountains, Lilin Experimental Forest Station, type of natural secondary forests, Pinus koraiensis, provenance test, superior provenance
