On the issue of assessing decorative qualities cut varieties of hybrid tea roses when grown on hydroponics

The rose is a leader in the cultivation of cut crops, the decorativeness of which is beyond doubt. Increasing the attractiveness of bouquet flowers is a priority task of modern industrial floriculture. A number of plant growth regulators can significantly improve the decorative qualities of flower-cutting products. During the research, it was proved that immunomodulatory with protective functions significantly increased the valuable decorative and economic properties of varieties of hybrid tea roses grown on low-volume hydroponics. With three-fold treatment of rose plants with Epin-extra, an increase in the size of the flower and its terry was noted. The burgundy-red variety Red Naomi was less exposed to the insolation of sunlight and retained the typical color for this variety. The use of a growth regulator increased the length and strength of the peduncle. The tea-hybrid rose of the Avalange variety significantly increased the duration of the bouquet in the vase. In the course of the experiment, we modified the scale of the score assessment of decorative tea-hybrid roses grown on low-volume hydroponics, more adapted to assess the most important economic qualities of the cut crop.
