چکیده

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.
