Abstract
The cultivation results of valuable medicinal plant Callisia fragrans in open-air hydroponic conditions have shown that the tested nutrient solutions didn’t have a significant influence on the productivity of the raw medicinal material. In case of using different nutrient solutions (Davtyan’s, Steiner’s, Chesnokov-Bazirina’s and Knop’s) the raw medicinal material exceeded the soil control with fresh (2.3-3.1 times) and dry weight (2.2-3.2 times), as well as with output of sum flavonoids
(2.3-3.3 times), extractives (2.6-4.0 times) and tannins (1.2-2.5 times) obtained from one plant.
