Abstract

This paper presents the chromosome numbers (2n) for 13 alien species (from the families Apocynaceae, Asteraceae, Brassicaceae, Fabaceae, Lamiaceae, Polygonaceae, Solanaceae) in the Novosibirsk Region. For Vincetoxicum hirundinaria Medik. (2n = 22) and Sisymbrium altissimum L. (2n = 14), chromosome numbers were determined for the first time on the material from Russia; for Betonica officinalis L. (2n = 16) – from Asian Russia; for Stachys annua (L.) L. (2n = 34) – from West Siberia. Chromosome numbers on the material from the Novosibirsk Region were revealed for the first time for Cosmos bipinnatus Cav. (2n = 24), Inula helenium L. (2n = 20), Sonchus oleraceus L. (2n = 18), Medicago sativa subsp. varia(Martyn) Arcang. (2n = 32), Rumex obtusifolius L. (2n = 20) and Solanum nigrum L. (2n = 48). For all the species studied, brief notes on their general distribution and dispersal in the Novosibirsk Region are provided, along with literature data on chromosome numbers from other regions of Russia.
新西伯利亚地区几种外来植物的染色体数目:后III
本文报道了新西伯利亚地区13个外来物种(夹竹桃科、菊科、十字花科、蚕豆科、Lamiaceae、Polygonaceae、Solanaceae)的染色体数目(2n)。为梅迪克黄腐霉。首次在俄罗斯材料上测定了其染色体数目;产于亚洲俄罗斯的Betonica officinalis L.(2n=16);产于西西伯利亚。来自新西伯利亚地区的材料上的染色体数量首次被揭示为“二羽状宇宙”Cav。(2n=24)、菊粉(2n=20)、苦菜(2n=18)、紫花苜蓿(Medicago sativa)亚种。varia(Martyn)Arcang。Rumex obtusifolius L.(2n=20)和龙葵L.(2n=48)。对于所有研究的物种,提供了它们在新西伯利亚地区的一般分布和扩散的简要说明,以及俄罗斯其他地区染色体数量的文献数据。
