Abstract

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. Real seed productivity is 3–4 times lower than potential. Pollen fertility is 55–60%. In the pre-winter period, rudimentary vegetative organs are formed in the kidneys of renewal. The cone of growth of escape winters at the II stage of organogenesis in the forest-steppe zone of Western Siberia.
