Chromosome numbers in some alien plant species of Novosibirsk region (Novosibirsk city): post I.

Abstract

Chromosome numbers (2 n) for 14 alien species (Apiaceae, Asteraceae, Brassicaceae, Commelinaceae, Fabaceae, Onagraceae, Poaceae) from the Novosibirsk city (Akademgorodok) are represented. For the first time the chromosome number is counted for Silphiodaucus hispidus (M. Bieb.) Spalik, Wojew., Banasiak, Piwczyński et Re - duron (2 n = 22) in Russia; for Cardamine flexuosa With. (2 n = 32), Commelina communis L. (2 n ≈ 48), Astragalus falcatus Lam. (2 n = 16), Lathyrus sylvestris L. (2 n = 14), Oenothera rubricaulis Klebahn, (2 n = 14) in Siberia; for Raphanus raphanistrum L. (2 n = 18) in West Siberia; for Centaurea jacea L. (2 n = 44), Erigeron canadensis L. (2 n = 18), Sonchus asper (L.) Hill. (2 n = 18), Sisymbrium officinale (L.) Scop. (2 n = 14), Lolium multiflorum Lam. (2 n = 14) in Novosibirsk Region. All species are provided with the brief information on their general spreading and distribution in Novosibirsk Region, as well as literature data on chromosome numbers.
