Abstract

Morphological and palynological studies were performed in 34 populations of 12  Achillea species belonging to three sections of Santolinoidea, Millefolium and Filipendulinae growing in Iran. Morphological studies were performed on 34 populations of 12 species. In total 33 morphological characters including 13 quantitative and 20 qualitative were scored. ANOVA test showed significant difference for most of quantitative characters among the species and populations studied. UPGMA clustering of the populations and species studied based on merely quantitative morphological characters and also based on both quantitative and qualitative characters separated populations of each species from the others indicating the use of these characters in species delimitation, however no resolved relationship could be obtained and the species from 3 sections stated in Flora Iranica are intermingled. The size of the pollen grains ranged from 22.4-30.0 µm, with similar P/E ratio, trizonocolporate, radially symmetrical, isopolar, spheroidal. The spines are pointed and are dome shaped broad based. The number of spine rows between colpi varies from 3 to 5 among the species. This feature can be determined easily in the polar view by light microscope.  The exine thickness varies from 2.4 µm to 4.5 µm among the species and pollen sculpturing is echinate in all. Clustering and ordination of species based on palynological characters also showed mixing of species from 3 sections mentioned in Flora Iranica.

Abstract [Persian]

بررسی خصوصیات مورفولوژیکی و دانه های گرده در جمعیت های 12 گونه Achillea از سه بخش Santolinoidea ، Millefolium و  Filipendulinae انجام گرفت. تعداد 33 صفت ریختی شامل 13 صفت کمی و 20 صفت کیفی برسی شدند. آنالیز واریانس وجود اختلاف معنی دار را در بسیاری از صفات کمی در میان جمعیت ها و گونه های مطالعه شده نشان داد. تجزیه خوشه ای بر اساس صفات کمی و نیز توام با صفات کیفی، جدایی جمعیت های یک گونه را از دیگر گونه ها نشان داد که بیانگر اهمیت این صفات در تاکسونومی و شناسایی گونه های جنس Achillea می باشد. روابط گونه ای بدست آمده از آنالیزهای فنتیکی، کلادستیک و روش Bayesian با مرزبندی میان سه بخش ارائه شده در فلورا ایرنیکا همخوانی ندارد و گونه های متعلق به این سه بخش در کنار یکدیگر قرار می گیرند. لدا بنظر می رسد تاکسونومی این گروه نیاز به بازنگری دارد.
