The Pattern of Seed Rain in the Broad-leaved Korean Pine Mixed Forest of Xiaoxing Mountains, China <Jour. Kor. For. Soc. 93(5):621~627 2006> Corresponding author kimjh@kangwon.ac.kr
We established 287 0.5㎡ circular seed traps and collected and identified fallen seeds in the traps every two weeks in 150 m x 150 m sample plot of the permanent nine hectare of experimental plot in 2005. The overall average density of seed rain was 864.2/㎡. Pinus koraiensis was recorded only 2.5/㎡ of fallen seeds mainly owing to consumption of people and animals. Even though most of seeds showed high proportion of purity, those of Korean white pine had low rate of purity due to the animal and microbiological predation. Most of seed dispersal have started from the middle to late August and come to an end on the middle of November. The density of Korean white pine seed rain in the forest gap was significantly different at P≤0.05 from in the closed canopy.
Key words: broadleaved-Korean pine mixed forest, seed rain, forest gap, seed dispersal
