Abstract

Fagus orientalis Lipsky is the most important tree species of the Hyrcanian Forests of Iran.For long time, forest residents throughout Hyrcanian Forests have traditionally recognized F. orientalis, considering the appearance (outlook) of trees, into two forms: black beech, and white beech. In this research, we tried to evaluate micro-morphological characteristics of leaf and pollen grains of black and white beeches in the Hyrcanian Forests. Our research showed that there are no significant differences in micro-morphological characters between white and black beeches.

Abstract [Persian]

راش شرقی (Fagus orientalis Lipsky) مهمترین گونه درختی جنگل‌های هیرکانی ایران است. جنگل‌نشینان این منطقه به‌طور سنتی با توجه به شکل ظاهری درختان راش، دو نوع راش به‌نام‌های راش سفید و راش سیاه را تفکیک می‌کنند. در پژوهش پیش‌رو سعی شد ویژگی‌های ریزریخت‌شناسی برگ و دانه گرده راش سفید و راش سیاه در جنگل‌های هیرکانی ارزیابی شود. نتایج نشان داد که ازنظر ویژگی‌های ریزریخت‌شناسی تفاوت معنی‌داری بین دو فرم راش وجود ندارد.
