Morphogenesis and Reproductive Ability Monocarpic Escape Hosta sieboldiana (Hook.) Engl. (Hostaceae) in the Conditions of the Novosibirsk Region

The results of studying the morphogenesis of monocarpic escape during the seasonal development of Hosta sieboldiana are presented. It is shown that organ-forming processes of generative organs occur in the spring-summer vegetation of the shoot. Generative shoot is formed at 75–76 of days to flowering. Established, that the cone of increase of the escape differentiates intrarenal II to VIII stages of organogenesis. The flowers are laid in the acropolis direction. Duration of flowering was 25–38 days, fruiting 29–30 days.
