Abstract

The pollen morphology of 26 species of Artemisia L. from 33 species that grow in Iran was investigated using light microscopy and scanning electron microscopy (SEM). Based on exine ornamentation observed under SEM, two types of pollen grains were recognized: type I, Exine surface have dense acute spinule or, Type II, exine surface have a sparse density of spinule. Pictures of all species and characteristics of pollen grain structure are presented.

Abstract [Persian]

ریخت شناسی دانه گرده 26 گونه از جنس .Artemisia L (درمنه) از 33 گونه درمنه ای که در ایران می رویند با استفاده از میکروسکوپ نوری(LM) و میکروسکوپ الکترونی (SEM) بررسی شد. بر اساس مطالعات تزئینات اگزین بوسیله میکروسکوپ الکترونی اسکنینگ، دو تیپ دانه گرده تشخیص داده می شود: در نوع I سطح اگزین دارای خارچه های نوک تیز ومتراکم است و در نوع II سطح اگزین دارای تراکم کمی از خارچه ها می باشد. تصاویر تمام گونه ها و مشخصات ساختار داخلی دانه های گرده ارائه شده است.
