Restoration of deforested areas by cypress seedling in southern coast of Caspian Sea (North of Iran)

Abstract

Two-year old cypress (Cupressus sempervirens var. horizontalis seedlings (1+1) were planted in two planting depths (20 cm and 40 cm) in a lowland deforested area located in south of Caspian Sea, north of Iran. The results after the first and second growing seasons revealed that planting depth influenced survival and vitality such that both variables showed better performance in deeper holes (40 cm). In both periods stem length as well as collar diameter did not increase with increased planting depth. In year two, compared to year one, survival reduced only in holes of 20 cm, vitally declined in both planting depths but growth enhanced. Generally it can be concluded that deeper holes are better suited for plantation of C. sempervirens in the site study.
