Year: 2025

Type: article

Abstract: This paper presents chromosome numbers (2n) for 11 alien species from the families Asteraceae, Boraginaceae, Brassicaceae, Cannabaceae, Fabaceae, Iridaceae, Onagraceae, Poaceae, collected in the Novosibirsk Region. For Astragalus contortuplicatus (2n = 16), Chamaecytisus ruthenicus (2n = 48), chromosome numbers were determined for the first time on the material from Russia; for Cerinthe minor (2n = 18) – from Asian Russia; for Solidago gigantea (2n = 36) and Iris pseudacorus (2n = 34) – from Siberia. Chromosome numbers on the material from the Novosibirsk Region were revealed for the first time for Senecio vulgaris (2n = 40), Epilobium adenocaulon (2n = 36), Lolium perenne (2n = 14). The mitotic metaphase plates’ photos of 8 species are given. For all the species studied, brief notes on their general distribution and dispersal in the Novosibirsk Region are provided. The literature data on chromosome numbers from Russia are given. In cases, when the chromosome number was first determined on the Russian specimens, the corresponding references from other regions of the World where presented.
