Features of the Development of Tulips in the open Ground of the Western Forest-Steppe

Abstract

The main stages of the development of Big Love, Double focus, Versace, Fabio, Esprit varieties in the open ground of the Western Forest-steppe are studied in the article. Also a comprehensive assessment of the decorative features, resistance to diseases, and compliance with the conditions of cultivation were studied. The most viable and decorative varieties of tulips are found out for growing in open soil. The study of the growth of tulips found that the plants reached a height of 13 cm to 38 cm. The lowest were representatives of the Fabio variety with an average length of stems 17,8 cm, and the most highly developed was the variety Big love – with pedicels 36 cm. Almost all tulip bulbs of the Versace variety formed additional smaller flower peduncles, each of which is fully bloom, which increases the decorative qualities of this variety. Flowering of all varieties ended on average 57 days after the appearance of leaves and generally lasted for 12–20 days. The smallest duration of flowering had a Versace variety – 9 days, the largest Fabio – 17 days. Obviously, the climatic conditions that emerged in the spring of 2017 were not very favorable for disclosing all the decorative features of the studied varieties of tulips. For final conclusions on the suitability of the Big Love, Double focus, Versace, Fabio and Esprit varieties for growing in the open ground of the Western Forest Steppe, additional observations are needed over the next few years.
