E-mail: [email protected] Keywords: Altai Republic, Amaranthaceae, Asteraceae, Caryophyllaceae, chromosome numbers, invasive species, Lamiaceae, Onagraceae, Poaceae. Summary. Chromosome numbers (2n) in 16 invasive plant species from the families Amaranthaceae, Asteraceae, Caryophyllaceae, Lamiaceae, Onagraceae and Poaceae are reported on the material from the Altai Republic for the first time. Among them, chromosome complements were first examined in Russia for Chaiturus marrubiastrum (L.) Ehrh. ex Reichenb. (2n = 24) and Oenothera villosa Thunb. (2n = 14). Five species: Amaranthus lividus L. (2n = 34), Elisanthe noctiflora (L.) Rupr. (2n = 24), Galeopsis speciosa Mill. (2n = 16), Oenothera biennis L. (2n = 14) and Bromus japonicus Thunb. (2n = 14), were studied first from Siberia. The most part of the species studied are diploids. The general distribution and the history of floristic findings of these species in the Altai Republic are given. The data on chromosome numbers published earlier on the material from Russia are cited. Числа хромосом инвазионных видов во флоре Республики Алтай: сообщение 2 М. Н. Ломоносова, Е. Ю. Зыкова, Т. В.

Приводятся данные о числах хромосом (2n) для 16 инвазионных видов из семейств Amaran- thaceae, Asteraceae, Caryophyllaceae, Lamiaceae, Onagraceae, Poaceae, впервые полученные на материале из Республики Алтай. Впервые для России определены числа хромосом у Chaiturus marrubiastrum (L.) Ehrh. ex Reichenb. (2n = 24) и Oenothera villosa Thunb. (2n = 14), впервые для Сибири – у Amaranthus lividus L. (2n = 34), Elisanthe noctiflora (L.) Rupr. (2n = 24), Galeopsis speciosa Mill. (2n = 16), Oenothera biennis L. (2n = 14) и Bromus japonicus Thunb. (2n = 14). Большинство изученных видов являются диплоидами. Для всех исследованных видов приводятся сведения по общему распространению, истории флористических находок на территории Ре- спублики Алтай и литературные данные по числам хромосом, полученные на материале с территории России. The Altai Republic is currently one of the regions further transformation in biological diversity of the attracting a large number of tourists from different flora. Invasive species, in their turn, may themselves regions of Russia and other countries. As a result, undergo evolutionary changes in the new condi- the vegetation is exposed to significant anthropo- tions. That is why, the comprehensive study and genic impact, which contributes to invasion of a biological monitoring of alien species in the natural large number of alien species in the area and leads to flora is becoming increasingly important.
