erodium (geranaiceae) species are distributed in different habitats of iran. some species are of medicinal importance while some are well known weeds. there are no chromosome counts for erdoium species of iran. chromosome numbers are given for six taxa of erodium (geraniaceae) from iran: e. cicutarium (2n=36), e. ciconium(2n=18), e. malacoides (2n=20), e. moschatum (2n=20), e. neuradifolium (2n...
شمارش کروموزومی 23 جمعیت متعلق به 3 جنس و 8 آرایه از تیره میخک ( زیر تیره alsinoideae) از ایران گزارش می شود. اولین گزارش کروموزومی برای گونه های s. persica (2n=28)، s. alsinoides (2n=2x=30) و mesostemma kotschyanum subsp. kotschyanum ( 2n=32) ارائه می شود. گونه های جنس stellaria به دو گروه تتراپلوئید و دیپلوئید تقسیم بندی می شوند. شمارش کروموزومی برای شش تاکسون از stellaria (caryophyllaceae) و...

Cytological information is absolutely lacking for the Iranian moss flora (Bryophytes). The present research, dealing with cytological studies on the following five species (including two expressions and one variety) of Iranian mosses, namely, Amblystegium riparium (Hedw.) B.S.G. “brevipes” expression(n=20), A. riparium (Hedw.) B.S.G. “pennellii” expression (n=9, 9+m, 9+2m), A. serpens (Hedw.) B...

This study concerns the cytotaxonomic investigations on twelve species belonging to three sections from the genus Vicia in Iran. A taxonomic background of the genus is given in brief. The previous counts reported for the genus in Index to plant chromosome number are summarized. In addition to one new count, the chromosome numbers of four species are reported for the first time. Briefly, the ...

Original meiotic or mitotic chromosome counts are presented for 17 species in 12 families of angiosperms from Iran. Chromosome counts for Amberboa nana, n=16 (Asteraceae) and Camelina rumelica subsp. transcapica, n=13 (Brassicaceae) are repoted for the first time. Chromosome numbers for six species including: Rhagadiolus stellatus (n=5), Campanula raponcoloides (n=34), Campanula trachelium (n=1...
