Breeding System of (Lamiaceae)
Gordeeva N.I., Talovskaya E.B.

Thymus mongolicus (Ronniger) Ronniger (Lamiaceae) is a valuable medicinal and aromatic plant. T. mongolicus is the implicitly polycentric dwarf shrub widely distributed in different environments of Tuva. The breeding system of T. mongolicus was studied in three steppe and meadow habitats. Statistically significant differences between bisexual and pistillate flowers of T. mongolicus were established based on three morphological features of the flower: the length of the upper lip of the corolla and the length of stamen filament of the upper and lower stamens (p 0.0001–0.016). The length of the upper lip of corolla of the bisexual flower is 1.3 times longer than that of the pistillate flower; the lengths of stamen filaments of upper and lower stamens of bisexual flowers are 3.7 and 4.1 times longer (respectively) than the length of staminodes of pistillate flowers. The stamens of the pistillate flowers are underdeveloped and do not form fertile pollen. The frequency of females occurrence in coenopopulations is insignificant (2.1–3.4% of the total number of generative individuals), and females are absent in some phytocoenoses. Reproduction of T. mongolicus occurs both by seed and vegetatively. The distribution of T. mongolicus individuals by ontogenetic groups showed that both pregenerative individuals (33.0–38.1% of the total number of individuals) and generative individuals (31.2–63.7%) are well represented in cenopopulations. Analysis of the ratio of genets and ramets in the steppe petrophyte coenopopulation showed the significant predominance of the vegetative individuals in all ontogenetic groups: in general, there are 3.7 times more ramets than genets. In the meadow coenopopulation, the germination of seeds and the spread of generative individuals is prevented by the relatively high total projective cover of the herbage. It can be assumed that the low occurrence of T. mongolicus females is a-ssociated with a low seed renewal and specificity of offspring inheritance.

Individual Morphometric Characters and Productivity of (Plantaginaceae) in the South Siberia (Republic of Khakassia)
Pimenov A.V., Efremov S.P., Sedel’nikova Т.S.

—Phytocoenotic and morphological features, as well as the productivity of the giant plantain (Plantago maxima Juss. ex Jacq.) in typical floodplain landscapes of southern Siberia were studied. The coenopopulations of P. maxima growing in natural and reclaimed areas of the Bely Iyus River valley in the Shirinsky and Ordzhonikidzevsky districts of the Republic of Khakassia were assessed. Under contrasting environmental conditions, in associations with significant share of P. maxima its productivity was 8.2 ± ± 0.58 kg × 102∕ha of air-dry, and 7.7 ± 0.54 kg × 102∕ha of oven dry aboveground phytomass. P. maxima share of the total phytomass varies from 5 to 15% in mesophytic associations with high species diversity on well-drained soils, and from 40 to 80% in xerophytic associations confined to mounds with sandy, sandy-gravelly or pebbly sandy soils. In P. maxima, the size and variability of vegetative organs increase in plants growing in more moist environments, while in drier habitats, the generative structures increase in the size and variability.

Effect of Dry Storage on Seed Germination of (Ephedraceae)
Borisova S.Z.

—Effects of dry storage under ambient laboratory conditions on germination and survival was tested for seeds of rare species Ephedra monosperma. The seeds without pregermination treatment were placed in Petri dishes with a moistened filter paper at room temperature 20 ± 3 °C. Seeds maintain high germination when dry stored for 5 years (mesobiotic), further storage leads to a sharp decrease in germination. At the same time, dry storage of seeds does not change the time of the beginning of germination, the duration of germination and the curve of seed germination. Freshly harvested seeds and seeds stored at room temperature germinate 2–4 days after seeding, 50% of seeds – in 7 days, and 98–100% – within 2 weeks. The seed germination curve has two peaks; the highest one is the first, which is observed on the 3rd day from the start of germination.

Comparative Analysis of the Component Composition of Flowers in Some Species of the Genus (Oleaceae)
Pupykina K.A., Polyakova N.V., Kudashkina N.V., Krasyuk E.V.

—Due to the insufficient knowledge of the lilac flowers component composition, a comparative analysis of 6 species of the genus Syringa L. from the collection of the South Ural Botanical Garden-Institute of the Ufa Federal Research Center RAS was carried out. S. emodi Wall., S. josikaea Jacg., S. komarowii Schneid., S. reticulata (Blume) H. Hara ssp. amurensis (Rupr.) P.S. Green et M.C. Chang, S. sweginzowii Koehne et Lingelsh, S. vulgaris L. were studied. The content of the major groups of biologically active compounds, namely flavonoids, hydroxycinnamic acids, tannins and organic acids, was established. The highest content of all identified groups of biologically active substances (BAS) was found in flowers of S. komarowii: flavonoids ‒ 4.25 ± 0.21%, hydroxycinnamic acids ‒ 6.13 ± 0.29%, tannins – 9.3 ± 0.5%, ascorbic acid ‒ 0.468 ± 0.022%, and organic acids ‒ 10.7 ± 0.5%. In S. emodi and S. sweginzowii the content of these BAS is little less than in S. komarowii, and the minimum amount of BAS was found in S. josikaea. A comparative analysis of the qualitative and quantitative profiles of the BAS major groups in some lilac species cultivated in the Republic of Bashkortostan shows the prospects for their further study with the objective of their possible use in scientific medicine, and for the development of herbal remedies.

Changes in the Individual and Group Composition of Polyphenols in Leaves of subsp. and as Related to the Chemical Elements Content in Soil and Plants on the Ultra-Alkaline Parent Rock Material
Boyarskykh I.G., Kostikova V.A.

—A comparative analysis of the main classes of biologically active polyphenols in extracts from the leaves of the medicinal species Spiraea chamaedryfolia L. (Rosaceae) and Lonicera caerulea L. (Caprifoliaceae) was performed. The features related to the macro- and trace elements’ content in soil and phytomass in coenopopulations of the Mountain Altai at the site with sporadic occurrence of serpentinites were studied. In the S. chamaedryfolia leaves high performance liquid chromatography identified 16 polyphenolic compounds. These polyphenols were attributed to different classes, namely phenol-carboxylic acids (3), flavonols (10), flavons (2) and one flavanon. As for the L. caerulea leaves, the analysis confirmed their polyphenolic composition, measured earlier, i.e. the presence of hydroxycinnamic acids, flavonols and flavons; but additionally, one more compound, identified as flavanone, was found. The study revealed species-specific shifts in plant secondary metabolism in response to specific edaphic properties and the level of macro- and trace elements accumulation in the leaves of plants, growing in the area with a natural geochemical anomaly.

Effect of Urban Environment on Ecological and Phytochemical Features of (Rosaceae) Flowers (the Case of the Donbass)
Vinogradova N.A., Glukhov A.Z.

—The article presents the results of a study of the effect of urban environment in the Donbass on the content of biologically active substances, heavy metals and antioxidant activity of the flowers of Crataegus fallacina Klok., a poorly studied non-pharmacopoeial species of the genus Crataegus L. Under technogenic pollution, in the flowers of C. fallacina a decrease in the concentration of carotenoids and an increase in the content of phenolic compounds (flavonoids, procyanidins, oxycinnamic acids, tannins, anthocyanins), ascorbic and free organic acids was detected. The hermetic response of the content of anthocyanins and procyanidins to the pollution level was observed. The flowers of C. fallacina have a high total antioxidant activity, which increases under technogenic load, indicating plants sufficient adaptation to the urbanized environment. The ability of C. fallacina plants to limit flow of cadmium and lead to generative organs was revealed. The concentration of mercury in flowers exceeds its concentration in soil. C. fallacina flowers harvested in the Donbass meet the regulations on the content of active substances and comply with the requirements with regard to the heavy metals content. The obtained results prove the practicability of using C. fallacina for pharmaceutical purposes along with pharmacopoeial species of the genus Crataegus, and the possibility of their harvesting for medicinal use in the Donbass.

Assessment of Total Mineral Content in Raw Materials of Ten Medicinal Plants from Roadside Biotopes (Voronezh Region)
Dyakova N.A.

The total mineral content in medicinal plants from the roadside and railside coenoses of the Voronezh region was studied. The pharmacopoeial plant raw materials of 10 species were evaluated: roots of Taraxacum officinale F.H. Wigg and Arctium lappa L.; herb of Polygonum aviculare L., Artemisia absinthium L., Leonurus quinquelobatus Gilib., and Achillea millefolium L.; leaves of Urtica dioica L. and Plantago major L.; flowers of Tanacetum vulgare L. and Tilia cordata Mill. For collecting medicinal plant raw materials, the minimum allowable distances from different types of roads and railways were determined based on the total ash content indicator. For different natural zones, the minimum allowable distance from the heavy traffic motorways is: forest zone – 210 m, forest–steppe zone – 240 m, and steppe zone (devoid of tree and shrub vegetation) – 380 m. For secondary low-speed roads and railways, the minimum recommended distance is 80 m.

Structure of the Ground Vegetation and Natural Regeneration of Tree Species in a 12–15-Year-Old Bilberry Pine Forest–Clear-Cut Ecotone Complex in the Middle Taiga Subzone
Genikova N.V., Moshnikov S.A., Teslya D.V.

—Logging in mature stands, where part of the forest is harvested in one or several cuts and part is retained (clear-cutting and alternate strip cutting) results in the formation of an ecotone complex: forest (F), transition from forest to clear-cut under the canopy (forest edge – FE), transition from forest to clear-cut outside of the canopy (clear-cut edge – CE), and the clear-cut itself (C). Strips 8 m wide on each side of the mature forest/clear-cut site border form the transitional zone. We studied the ground vegetation composition and structure, and the natural regeneration of woody species (Pinus sylvestris L., Picea abies (L.) H. Karst., Betula sp., Populus tremula L., Sorbus aucuparia L., Juniperus communis L.) in the bilberry pine forest – clear-cut ecotone complex 12–15 years after the stand removal. The studies demonstrate that each of the four zones of the ecotone complex formed after logging of the mature forest has its own structural features of ground vegetation and undergrowth (including tree regeneration). The typical forest (F) habitat is characterized by the minimum number of young regeneration of Pinus sylvestris, Picea abies, Betula sp., Populus tremula, and Sorbus aucuparia and, on the contrary, by the highest abundance of lingonberry V. vitis-idaea L. and bilberry Vaccinium myrtillus L., and the maximum height of bilberry plants and their yield. The amount of tree regeneration in the FE is almost the same as in the F zone. The projective cover, maximum shoot height and yield of bilberry, and maximum shoot height of lingonberry in the FE zone are reliably lower than in the F zone. The transitional zone on the clear-cut side (CE) and the clear-cut itself (C) are distinguished from the forest sections of the ecotone complex (F and FE zones) by a greater number of deciduous and pine regeneration and the low abundance of dwarf shrubs. The clear-cut itself (C) differs from the CE by the higher abundance of grasses and forbs and an established tree regeneration layer composed of pine, birch, and aspen.
