Abstract

The paper analyzes the features of seasonal development ofTulipa tschimganicaBotschantz. in the conditions of the recipient region. Comparative morphometric characteristics ofex situandin situare given. Representatives of the speciesT.tschimganicagrowing in high mountains are successfully acclimatized in the Novosibirsk Region. Late flowering and resistance to viral disease variegation adds value to this species in floriculture and gardening in the spring. The temperature characteristics of the initial stages of phenophases are established. The beginning of flowering in six of ten years of observations occurred in the second decade of May. By duration, flowering can be characterized as short 78 days, with an average duration of 1012 days and a long one 1315 days, respectively. It was found that, despite the high rates of maximum and average daily temperatures, lower temperatures increase the flowering period ofT.tschimganica. The flowering period in the recipient region, compared with the city of Tashkent, shifts by two months and starts from the second decade of May. The range of experimental plants morphometric parameters, such as plant height, leaf width, length and width of the ovary, and fruit width, increases. The rest of the studied parameters remainedin situ. The study of the ontogeny of individuals grown from seeds collected from introduced plants is being carried out. To date, the plants are going through a long pregenerative period of ontogenesis. Successful completion of the full cycle of annual shoots development and the formation of high-grade mature seeds characterize this species as successful for introduction and use in gardening in Novosibirsk.
