Abstract :

This study was designed to investigate the effects of gap size on seedling of oreintal beech (Fagus orientalis Lipsky) survival in GAP SIZE (2/0, 5/1, 7 ar) with an open space  adjacent  to  the  nursery  Avrymlk  Sangdeh.  in  the  center  of  each  gap,  were prepared 8 plots of 2.5*2.5 m and were planted 36 seedlings in each plot. The results revealed that the percentage of survival of nurseries seedlings after the fourth growing season showed significant differences in the various gap areas. Nurseries and forest Seedlings freshness in gaps with area smaller was significantly higher than the gaps with area larger. Gap area affected on nurseries seedling significantly so that larger gaps diameter was higher. Maximum value height growth was for nurseries seedlings in 600 m2  gap. Gap effect on the terminal bud (P< 0.05)  was significant and the greatest amount was for forest seedlings in open space.
