Determinimg the Most Suitable Shade Rate for Producing Beech (Fagus orientalis Lipsky) Seedlings in a Mountain Nursery

In order to determine the most suitable shade rate for producing beech (Fagus orientalis Lipsky) seedling in a mountainous nursery, three wooden shelters with shade levels of 33,50, and 60% as well as one with full light were examined in a completely randomized block design with four replications. It was carried out in Urimelk nursery (located at 1550 meter altitude), of Farim forest company, north of Iran. This study indicated that after one growing season, effect of shade on survival rate was greater than 90%. Difference among hight growths was significant too. Hight growth increased with increasing light, but shade levels did not produce significant differences in growth of collar diameter.
