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

Abstract

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
coinpany, 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
