ABSTRACT

Germination and early growth of Fagus orientalis seedling were studied in four stands with different canopy closures (closed, semi-closed, relatively-opened and opened stands) under a dominant beech forest, located in north of Iran. For this purpose, 196 beech seed-sown plastic pots (in four plots of 49 units) were set up under each canopy closure. In the beginning of the first growing season germination rate ranged between 78.1 and 84.7% in different stands but there was no statistically significant difference of this term in the stands. In the end of the first growing season survival rate of seedlings was 73.9-76.1% under closed and semi-closed stands. It decreased significantly to 31.7 and 18.0% under relatively-opened and opened stands, respectively. Shoot length was, in the order 70 and 90 mm in closed and semi-closed stands. It decreased to 40 and 30 mm in relatively-opened and opened stands, respectively. Vitality appeared mostly with high quality in closed and semi-closed stands and with low quality in relatively-opened and opened stands. Leaf biomass reduced in closed stand. There was an increase for leaf area in semi-closed stand and for Specific Leaf Weight (SLW) in relatively-opened and opened stands. Generally, the investigation shows that in the first growing season most characteristics of beech seedling were benefited from more favorable conditions in the denser stands (closed and semi-closed canopies).
