Features of growth and development of Scutellaria baicalensis Georgi under conditions of introduction in the Middle Urals

Abstract

Abstract. An experiment on the topic “Features of the growth and development of Scutellaria baicalensis Georgi under conditions of introduction in the Middle Urals” was carried out at the educational farm “Uralets”. Purpose of the study: to study the influence of the feeding area on the growth and development of Scutellaria baicalensis Georgi. The objectives of the study were to study the influence of the feeding area on: the dynamics of height and average daily growth, dates of the onset and timing of phenological phases, biometric indicators of leaves and inflorescences, structural composition of aboveground biomass, productivity of aboveground and underground biomass. Research methods. The experiment scheme includes 3 options: 1 variant – 33 × 30 cm (990 cm2) – control; 2 variant – 33 × 45 cm (1485 cm2); 3 variant – 33 × 60 cm (1980 cm2). Results. It was found that an increase in the feeding area enhances the differentiation of plants in terms of the rate of passage of phenological phases. The earliest transition to the generative stage of development was noted in variants II and III (24.06). The maximum average daily gain was observed in the II and III decades of July, according to the variants it varied from 0.78 (1st stage) to 1.22 cm/day (III stage). The highest biological productivity was obtained in variant 3 with a feeding area of 33 × 60 cm; on average, it reached 251.5 g per plant, which is 162.2 g (181.6 %) higher than in the control. Scientific novelty. For the first time, there was studied, the influence of the feeding area on the most important aspects of the growth and development of Scutellaria baicalensis Georgi in the conditions of the Middle Urals. The optimal feeding area (1980 cm2) has been established, at which the Scutellaria baicalensis Georgi is able to form a fairly high productivity.
