PECULIARITIES OF ONTOGENESIS AND POPULATION AGE STRUCTURE OF PULSATILLA PATENS (L.) MILL
DescriptionIn the article we have investigated the ontogeny and the peculiarities of the passage of its stages from Pulsatilla patens (L.) Mill. We have characterized the morphological features of the developmental stages. The age structure of populations and the influence of anthropogenic factors on it have been set

Description
The article discusses the features of the accumulation of essential oil in the collection samples of Oregano studied in the foothill zone of the Crimea. The range of variability of the mass fraction of essential oil of Origanum vulgare (from trace amounts to 0.53% of the bone dry weight). We have revealed that the greatest amount of essential oil accumulates in the inflorescences during the flowering phase

FEATURES OF MINERAL WASTE AND THE EXPEDIENCY OF THEIR USE IN THE FOR-MATION OF COMPLEX COMPOSTS
DescriptionThis article summarizes the results of the study of physical, chemical and biological characteristics of mineral waste; it analyzes the specific features of its behavior when applied to the soil in pure form and in complex compost; the possibility of using some of them as an ameliorant for improving the fertility of soil common in the steppe zone of the region

FEATURES OF THE CULTIVATION OF PROPIONIBACTERIUM SHERMANII STRAIN
DescriptionWe have presented materials about nutrient media for growing and industrial the cultivation of Propionibacterium shermanii: Trypticase Yeast Extract Glucose Medium, the culture medium Ellinger and ATCC Medium 33. We have studied pH change and its impact on the biomass accumulation of propionic acid microorganisms. We have also defined the best time of cultivation

FEATURES OF PLANT INTRODUCTION IN THE KUBAN REGION
DescriptionThe features of introduction of trees, shrubs and herbaceous species in terms of the Krasnodar region and the south of the CIS are analyzed, the specificity of this process for deciduous and coniferous species, and grasses at their development in the spring and autumn periods, the allocation of forming niches generative organs, microsporogenesis, etc. are discussed. Opportunity to adapt different kinds of herbs and species of shrubs and trees, taking into account seasonal development with allocation of exotic species in the annual cycle of vegetation critical periods for the growing season Kuban has been considered. The results of the horizontal and vertical introduction in the study of the imported seeds and planting material of different species of trees, shrubs and grasses are discussed

Description
The peculiarities of vegetative propagation of ornamental plant Hypericum forrestii (Hypericaceae) by cuttings under conditions of the Black Sea coast of the Krasnodar region have been studied. It has been found that summer cuttings of lignified and semi-lignified propagula are the best for vegetative propagation of Hypericum forrestii

Description
The accumulation features of radionuclides in the epitaphic pylaisiella moss (Pylaisia polyantha) in the territory of the city of Rostov-on-Don have been considered. The specific activities of 137Cs, 226Ra, 40K, and 232Th in the samples of moss, soils, and aerosol air have been compared. The capacity of Pylaisia polyantha to accumulate radionuclides has been estimated for four radionuclides (137Cs, 226Ra, 232Th, and 40K) with consideration for the background level. On the basis of radionuclide analysis, zones in the city of Rostov-on-Don with the highest accumulation coefficients of 137Cs, 226Ra, 40K, and 232Th were revealed. These were primarily the zones with both industrial and traffic loads and the motor transport zones

THE ADAPTABILITY OF VARIETIES OF WEIGELA (WEIGELA THUNB., CAPRIFOLIACEAE) IN THE CITY OF KRASNODAR
DescriptionThe success of the introduction of plants depends on their vitality and adaptation to new existence conditions. Different adaptability of plants depends not only on the species, but also on their individual properties. The article studies the characteristics of adaptation of the perspective ornamental shrubs - Weigela, Caprifoliaceae. We have shown the variety’s morphological features, the growth and development of varieties of Weigela that have been taken during the research in the experimental Garden Center (NСRRIH&V). There is an estimation of growth rate and its dependence on the structure of different varieties of Weigela’s crown. We have examined the features of the formation of leaves: we have defined the indicators such as the number, length and leaf area; biomass, dry weight; productivity of leaves. We have estimated Weigela leaves photosynthetic activity in the introduction’s region. We have determined the number of photosynthetic pigments in the studied cultivars of Weigela’s leaves. We have found out that Weigela’s leaves pigments’ synthesis largely depends on their natural color, quality and the vegetation phase. These studies allow us to conclude that all the studied varieties of Weigela can be characterized by a high degree of adaptation and deserve widespread in Krasnodar gardens and parks due to the high decorative flowering period
