Abstract

The micromorphology and distribution of trichomes in leaf surfaces of speciesbelonging to Morus, Ficus, Broussonetiaand Madura which are native or cultivated in Iran werestudied. Three types of trichomes including; glandular, nonglandular and cystolith trichomes showedcharacteristicfeatures in thesegenera of Moraceae. Glandular trichomes are usuallywith short stalk and spherical or elongatedhead. The nonglandular trichomes are unicellular but differentiatedinto 3 types as large, bristle and bracket types. Cystolith trichomes withswollen base and mucronate apex are alsopresent.

Abstract [Persian]

تنوع کرکها از نظر شکل ظاهری و پراکنش آنها در سطح برگ گونه‌های متعلق به جنس‌های Morus (توت)، Ficus (انجیر)، Maclura (توت آمریکایی) و Broussonetia (توت کاغذی) که بطور طبیعی یا کاشته شده در ایران رویش دارند، بررسی و شرح داده می‌شود. وجود سه نوع کرک شامل: کرکهای غده‌ای، کرکهای غیرغده‌ای به اشکال مختلف و بخصوص کرکهای دارای سیتولیت از صفات مشخص و دارای ارزش تاکسونومیک در گونه های مورد مطالعه می‌باشند.
