Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2013, Vol 3, Issue 5
Abstract
Quercus is the largest genus in the family Fagaceae with about 300-600 species. This genus includes evergreen and deciduous shrubs and trees extending from cold latitudes to tropical Asia and Americas. It is the most common genus of Fagaceae in forests of Iran. The genus shows a remarkable morphological variation in these forests. Quercus castaneifolia is one of the most important species of Iran`s native oaks, distributed in the Hyrcanian Forests. As a main species of the Hyrcanian forests, it forms two important forest communities in this zone: Querco-Buxetum in the Caspian coast plains and Querco-Carpinetum in the lowlands (Fig. 1). Ten 4-yearSeedlings were collected from a field spread in the Kandesar Village, Roudsar District, Gilan Province, Iran with area about 5 ha (with same growing condition such as aspect, light and soil) in North Iran with loam and silty loam soil. According to the above research and evaluation with SAS System, we find that the annual growing of (Quercus castaneifolia) in 4th year was longer than 2, 3 and 1. Annual growing in 3rd year was about 2.35 cm more than 2nd year. There reason of this difference was different in annual precipitation in those years.
