New Chromosome Counts in the Tribe Anthemideae (Astraceae) from Iran

Abstract

Summary Seventeen chromosome counts of 15 taxa (15 species) in the tribe Anthemideae of the family Astraceae are reported. All taxa were collected from Zanjan, Iran. Six counts are new reports (including Achillea talagonica, Anthemis coleopoda, Anthemis haussknechtii, Tanacetum pinnatum, Tanacetum polycephalum, and Tanacetum kotschyii), four are not accordance with previous counts (or are new reports for ploidy levels) and reminders are confirmation of very limited (one to six records) previous data. All of studied taxa have the basic number xϭ9, with ploidy levels ranging from 2ϫ to 10ϫ.

New Chromosome Counts in some Species of the Genus Artemisia L. (Asteraceae) from Iran

“…In this population, the chromosome number was recognized as 2nϭ3xϭ24. This is different from other prior reports Vallès 2001, 2010 Saedi et al 2006, Chehregani andMehanfar 2008). This is the first report of triploidy level as 2nϭ3xϭ24 for this species.…”

“…Our data is different from above mentioned reports but is accordance with some earlier report (Mendelak and Schweizer 1986, Yan et al 1989, Qiao et al 1990) and also our report about Zanjan population of Iran (Chehregani and Mehanfar 2008).…”

“…Several counts have been carried out on different wild population of this species, which shown their chromosome number as 2nϭ2xϭ16 in the west Azerbayjan population (Saedi et al 2006), 2nϭ2xϭ18 in Zanjan population (Chehregani and Mehanfar 2008), 2nϭ2xϭ16 and also 2nϭ4xϭ36 to 32 in Armenian and Iranian population . Our data is the confirmation of reports of Saedi et al (2006) and is different from others.…”

Karyomorphological study of nineTanacetumtaxa (Asteraceae, Anthemideae) from Iran

“…Chromosome counts in many members of Anthemideae have already been reported (e.g. Torrell et al 2001;Inceer and Beyazoglu 2004;Vallès et al 2005;Garcia et al 2006;Inceer et al 2007Inceer et al , 2012Li et al 2008;Chehregani and Mehanfar 2008;Chehregani and Hajisadeghian 2009;Chehregani et al 2011).…”

“…Karyological studies of the genus Tanacetum in Iran have been performed only by a few researchers (Chehregani and Mehanfar 2008;Chehregani and Hajisadeghian 2009;Chehregani et al 2011) and the reported chromosome numbers include 2n = 18, 27, 36, 54, 72 and 90. Chromosomal data are still scarce or not existent for numerous Tanacetum taxa.…”
