In the culture in the South Urals (Republic of Bashkortostan)

The purpose of research is to study the features of the onset of the main phenological phases of development, biomorphological and reproductive indicators of four taxa of aromatic plants from the genus Monarda (Monarda): two varieties of M. didyma L. (m. double) - f. caerulea and f. rosea, a variety of M. fistulosa var. menthifolia (Graham) Fernald (m. fistulose) and M. media Willd. (m. average). The studies were carried out in the culture conditions of the South Ural Botanical Garden-Institute of the Ural Federal Research Center of the Russian Academy of Sciences in 2020-202. based on the collection "Aromatnyj Sad". The study was carried out on 25 model plants of each taxon according to the guidelines developed for botanical gardens. Vegetation starts in the third decade of April. The duration of flowering of the studied Monards is about a month - from the second decade of July. The period from mass flowering to full maturation of seeds averages is 45-50 days. Weight of 100 pcs. seeds of M. fistulosa var. menthifolia is 0.04 g; in M. media - 0.038; in M. didyma f. caerulea - 0.039; in M. didyma f. rosea - 0.037 g. The tallest is M. didyma f. caerulea, undersized - M. didyma f. rosea, it is inferior to other monarda taxa in terms of most morphometric parameters. M. media is distinguished by the largest number of flowers in an inflorescence, but a smaller number of inflorescences on a generative shoot. Less leafy plants are characterized by M. fistulosa var. menthifolia, while the species forms the smallest number of generative shoots. By definition of the success of the introduction, four specimens of the genus Monarda included in the studies go through a full cycle of life development and have shown themselves to be highly resistant plants.
