VARIATION IN LEAF MORPHOLOGY OF PARROTIA PERSICA ALONG AN ELEVATIONAL GRADIENT IN EASTERN MAZANDARAN PROVINCE (N. IRAN)

In order to investigate the variation within and among populations of Parrotia persica C.A. Meyer based on leaf morphological traits, three populations were selected from Behshar area, in the east of Mazandaran Province. The populations selected along a transect in different altitudes of ۱۸۲, ۳۴۰, ۵۴۰ meter above the sea level, respectively. In each population, ۱۰ trees were selected and some leaves were collected from middle crown in early October. Leaves mixed together and then five leaves were selected randomly for study.
