| چکیده | ||
| Pollen morphology of the genus Rheum (Polygonaceae) from Iran was studied by light microscope (LM) and scanning electron microscope (SEM). Pollen grains are usually auxiliary symmetrical, isopolar and tricolpate in equatorial view, while circular in polar outline. Exine sculpturing is variable and are sparsely faveolate to perforate, less microechinate (Rh. turkestanicum), perforate-favusus, microechinate (Rh. ribes) and perforate to foveolatus, densly microechinate (Rh. persicum). On the basis of qualitative and quantitative characters identification keys for species were prepared. | ||

| چکیده [English] | ||
| مورفولوژی دانه گرده جنس Rheum L. (Polygonaceae) در ایران با استفاده از میکروسکوپ نوری (LM) و میکروسکوپ الکترونی نگاره (SEM) مطالعه شد. دانههای گرده در نمای قطبی معمولا دارای تقارن محوری، در دو قطب مشابه، وسه شیاری اند در حالی که در نمای استوایی دایرهای شکلاند. تزیینات سطح اگزین متغیر است و به شکلهای با منافذ پراکنده تا منفذدار، میخچههای پراکنده (Rh. turkestanicum)، منافذ کشیده، میخچه دار (Rh. ribes) و یا منافذ نوک سوزنی- با تراکم بالایی از میخچهها (Rh. persicum) دیده میشوند. بر اساس صفات کمی و کیفی مطالعه شده کلید شناسایی گونههای ایران ارایه میشود. | ||
