Abstract

Growth regulators had a significant effect on the morphometric parameters of graceful zinnia, among which the most effective was Epin-extra. Being treated twice with epibrassinolide, zinnia plants had a more saturated color range. Zircon (a drug from the group of hydroxycinnamic acids), as it turned out, had a lesser effect on morphometric parameters than Epin-extra. The Mechta (in English translation as Dream). Further in the text this name will be used) variety turned out to be more resistant to unfavorable weather conditions and in comparison with the Oranzhevyy korol’ (in English translation as Orange King). Further in the text this name will be used variety, it more easily tolerated recurrent cold and droughts during the growing season. In addition, the Dream variety turned out to be more even in height and in the formation of lateral flowering shoots, which is important to create ornamental flower compositions. The use of growth regulators and mineral fertilizers increased zinnia visual perception. Among the varieties, the variety Dream had the most preferable decorative qualities.
