Abstract


Rose flowers are in great demand among the population. The use of growth regulators on the culture of roses allows you to improve the biological properties of varieties, their potential, as well as increase the yield and decorative colors. The purpose of the research was to determine the effectiveness of the action of plant growth regulators Biolan, Regoplant, Bionur, Bouton, Humisol-H and Zircon on growth, development, decorative qualities, yield dynamics and rose productivity under conditions of modern winter Venlo greenhouses. The study was conducted on plants of a variety of hybrid tea type Avalange of the Netherlands breeding company Lex +. Experimental work was carried out at the farm “Askania-Flora" during 2015-2016. Threefold spraying of plants with growth regulator solutions was applied: 7 days after planting, during budding and at the beginning of flowering. The control plants were not treated with growth regulating agents. As a result of research, it has been established that growth regulators Bud and Bionur accelerated the formation of flowering shoots and the time for slamming on plants, shortened the period of bud appearance and flower development. Established a different effect of preparats on the dynamics of the arrival of the crop by month. The influence of growth regulators Biolan, Bionur and Bud on the increase in total yield, plant productivity and decorative qualities of the rose flower has been determined. The results obtained should be taken into account when laying rose stands in winter greenhouses to regulate growth processes, plant development and increase crop yields.
