ASSESSMENT OF THE PROSPECTS OF SOME SPECIES OF THE FAMILY LAMIACEAE L. IN THE CONDITIONS OF THE STAVROPOL UPLAND

Abstract

At the present stage, in the Stavropol Botanical Garden in the collection of medicinal plants, work is underway to study and select an assortment of species suitable for improving the environment. Due to the deterioration of the environmental situation, this area of research is very relevant. From a wide range of medicinal plants, species of the Lamiaceae L. family are of great interest. The purpose of the research is to study the prospects of 18 species of this family when grown in the conditions of the Stavropol upland. The climate is temperate continental, semi-dry, belongs to the zone of unstable humidification of the Stavropol Territory, the altitude above sea level is 640 m. The average annual temperature is +9.7...+11.0°C, the average annual precipitation - 630 mm. The method of research of species includes: description of life forms, regular phenological observations, assessment of winter hardiness, frost resistance, drought resistance, degree of damage by diseases and pests according to the method of R.A. Karpisonova with some modifications. The studied species are represented by such life forms as wintergreen herbaceous perennial, herbaceous biennial, half-shrub, evergreen half-shrub, semifrutex. All plants are resistant to the climatic conditions of the Stavropol upland, including the frosty and dry periods (with the exception of giant-hyssops and horsemint). Most plants are resistant to pests and diseases. The assessment of the prospects of all the studied taxa is high, and is expressed in balls from 17 to 20, the maximum number of balls in species is in spicate lavender, creeping thyme, garden sage. The results of the conducted studies indicate the prospects of the studied species of the Lamiaceae family and allow them to recommend them for cultivation in the conditions of the Stavropol upland.
