Methods of increasing the seed productivity of the new variety of sage medicinal Fioletovy Aromat

Abstract

Relevance. Salvia officinalis L. is an important essential oilseed crop with anti-inflammatory, antimicrobial and antioxidant properties. Providing the pharmaceutical industry with raw materials of Salvia in full is possible due to the expansion of production areas and the availability of the maximum amount of highquality seed material of new promising varieties.Methods. In 2019-2022 in the conditions of the North Caucasus branch of VILAR on a new variety of Salvia Fioletovy aromat II year of vegetation by staging small-scale experiments were conducted to study the systematic application of organomineral fertilizer – EcoFus and growth regulators of different mechanism of action – Zircon, Epin-extra, retardant Hardy to increase seed productivity and seed quality. The area of the experimental plots was 12 m2. Treatment with EcoFus was carried out at the beginning of regrowth, and with bioregulators – during the budding phase. The consumption of the working solution is 300 l/ha. Control variants of medicinal crops were treated with water.Results. Application of EcoFus in the phase of regrowth contributed to the activation of the intensity of photosynthesis and increase in the accumulation of plastic substances, which allowed plants to enter the generative phase earlier, the budding phase came 2-3 days earlier than in the control. Subsequent treatment of budding plants with growth regulators led to earlier and more friendly flowering, the time of seed ripening was reduced by 3-4 days. The highest efficiency was observed in the variants of joint application of EcoFus with Zircon or Hardy, where the number of inflorescences on plants increased, seed setting and seed productivity increased by 37-42%, seed quality also improved – weight of 1000 seeds increased by 9-10% and germination by 6-7%.
