摘要

报道了伊朗9个维管植物科的10个特有种和1个非特有种的原始减数分裂或减数分裂和有丝分裂染色体数目。首次测定了沙棘果、白杨、多枝花、山楂果、木犀草、木犀草、木犀草、木犀草、木犀草、木犀草和山茱萸的染色体数目。桃桃属和黑桃属的染色体计数与前人一致。本文首次报道了黑穗草和葱的配子染色体数目。此外，还报道了棘果属(schahrudicum)和氨果属(Dorema amiacum)存在辅助染色体，这是棘果属(Acantholimon schahrudum)和氨果属(Dorema amiacum)中首次记录到B染色体。

Chromosome number and meiotic behavior in several plant taxa from iran

Original meiotic or both meiotic and mitotic chromosome numbers are reported for ten endemic and one non endemic species in nine vascular plant families from Iran. The chromosome numbers of Acantholimon schahrudicum, A. truncatum, Anthochlamys multinervis, Campanula perpusilla, Cousinia calcitrapa var. interrupta, Dorema ammoniacum, Euphorbia gedrosiaca, and Hyocyamus orthocarpus were determined for the first time. The chromosome counts for Astrodaucus persicus and Hedysarum criniferum agree with previous ones. The gametic chromosome numbers for Hedysarum criniferum and Allium stipitatum are reported here for the first time. The occurrence of accessory chromosomes are also reported for Acantholimon schahrudicum and Dorema ammoniacum, being the first records of B chromosomes in the genera Acantholimon and Dorema.
