Abstract


The article presents the results of the research studying the vegetative and seed reproduction of ornamental kinds of Symphytum asperum and Cyanus montanus which are becoming wild. Besides, their potential invasiveness in South Karelia region conditions is assessed. It is stated that their reproduction is associated only with cultivated areas. Vegetative reproduction provides their transition into cultural species, but the indicators of their vegetative reproduction (the length of rhizomes, the amount of buds) are significantly lower than the aborigine Tussilago farfara L. has. The seed production of the plants (the amount of seeds, their germinating ability) is surely lower than the invasive kind of Impatiens glandulifera Royle has in Karelia. The reproductive potential of the species studied is insufficient for drawing the conclusion that these species running wild are becoming invasive species.

Key words


Symphytum asperum, Cyanus montanus, reproduction, naturalization, biological invasions.
