VITALITY AND AGE STRUCTURE OF CОENOPOPULATIONS OF (BECKMANNIA SYZIGACHNE (STEUD.) FERN) AND (CALAMAGROSTIS LANGSDORFII (LINK) TRIN) UNDER CONDITION OF THE LENAVILUY INTERFLUVE

abstract 1301706013 issue 130 pp. 204 – 216 30.06.2017 ru 37
The article presents the data on vitality and age structure of Beckmannia syzigachne and Calamagrostis langsdorffii соеnopopulations under conditions of the Lena-Viluy interfluve. The study revealed 3 types of vitality of Beckmannia syzigachne (prosperous, equilibrium, and depressive), 2 types of vitality of Calamagrostis langsdorffii (prosperous and depressive). The age spectrum in both species is normal, non-complete, left-sided. According to the delta-omega classification, the coenopopulations are considered to be young

INVESTIGATION OF TRACE ELEMENT COMPOSITION OF RAW STEVIA REBAUDIANA BERTONI MATERIALS

abstract 1301706020 issue 130 pp. 290 – 299 30.06.2017 ru 36
The article gives an analysis of the elemental composition in raw materials of stevia. Stevia plant is able to regulate the flow of heavy metals, allowing them, on the one hand, actively oppose the excessive intake of toxic elements and on the other hand, selectively cumulate essential elements. The contents of essential elements in plant raw materials do not exceed the acceptable standards regardless of the growing conditions

RETROSPECTIVE ANALYSIS AND THE PRESENT STATE OF PIKEPERCH (STIZOSTEDION LUCIOPERCA (L.) STOCK AND FISHING IN THE AZOV LIMANS OF THE KRASNODAR REGION

abstract 1301706025 issue 130 pp. 335 – 347 30.06.2017 ru 52
The author describes the dynamics of commercial catches and the forecasts of pikeperch catch in 2010- 2016 with an analysis of the causes that affect the state of stocks. The analysis of the effectiveness of the recommended pikeperch catch has been made taking into account the factors that affected the fishery. Researches were carried out to study the population structure, seasonal distribution, migrations and other characteristics of the pikeperch populations in the Azov limans. The obtained data made it possible to assess the state of the pikeperch stocks and give recommendations on their rational use. Based on the results of ichthyological studies, the pikeperch age, length and weight composition have been determined and its biological state has been studied. The preliminary forecast of the stocks and the recommended pikeperch catch in the Azov limans for 2018 is given. The forecast of the recommended pikeperch catch in the Azov limans for 2018 is based on the analysis of the stocks of commercial fish species for a number of years of observations, taking into account the total mortality rate under the influence of the fishery load (commercial mortality coefficient) and the amount of replenishment of commercial population with fish mature for the first time

EFFECT OF MECHANICAL AND CHEMICAL PREPARATION OF ABIES ON POTATO (SOLАNUM TUBEROSUM L.) MORPHOGENESIS IN COURSE OF MICROPROPAGATION IN VITRO

abstract 1301706046 issue 130 pp. 670 – 679 30.06.2017 ru 12
The article gives the results of the study of an effect of mechanochemical powder of wood green of Abies (MPA) on potato morphogenesis in vitro. The study involved the hormone-free nutrient mediums (MS, ½ B5, ½ LS) for growing microcuttings from preliminary obtained aseptic plants. Plant morphogenesis was observed on the 15th and 30th days. At that, the number of developed shoots, plant height, leaves number, rhizogenesis rates, root number and length were estimated. MPA appeared to have the regulatory effect on morphogenesis of potato microcuttings. Based on mineral composition of the nutrient agar medium for potato microcuttings growing, MPA at 100 mg/l concentration induced root development (½ B5 medium), reduced height of shoots (MS medium), while the number of leaf blades was not affected

COENOPOPULATION STATE OF SOME FABACEAE SPECIES UNDER CONDITIONS OF THE MIDDLE LENA RIVER VALLEY

abstract 1301706049 issue 130 pp. 712 – 726 30.06.2017 ru 19
The study concerns the results of the study of coenopopulations of the following Fabaceae species: Medicago falcata, Oxytropis candicans, and Onobrychis arenaria under conditions of the Middle Lena River. The study was conducted in Yakutsk vicinities, 13 km north-east of the city. It is stated that all the studied coenopopulations are normal. Rather small values of substitution and recovery indices evidence certain problems in self-maintaining processes. The age structure analysis using two age indices, “delta” and “omega”, allows to classify the coenopopulations of Medicago falcata, Oxytropis candicans and Onobrychis arenaria in phytocoenoses of the Lena River valley as normal young populations. They were prevailed by juvenile, immature, virginile, and young reproductive plants

THE SPECIES COMPOSITION, BIOMASS, QUANTITY OF THE COASTAL ZOOBENTHOS AND FISH CAPACITY IN SOME OF KARASUN LAKES

abstract 1301706054 issue 130 pp. 774 – 788 30.06.2017 ru 20
We have presented information about species diversity of the coastal zoobenthos in some of Karasun lakes, Krasnodar. We have shown methodology information and reported the research area. We have made a taxonomic analysis. The biomass and the quantity of the main zoobenthos groups were calculated. Based on the two main fodder objects - Olygochaeta and Chironomidae and the P/B coefficient, there was calculated zoobenthos production of the studied lakes. The potential fish capacity was defined

SMDS "POTOK" 1.0 – A SIMULATION MATHEMATICAL MODEL FOR CALCULATION OF DISTRIBUTION AND SEDIMENTATION OF TECHNOLOGICAL ALLUVIUMS IN WATERCOURSES FOR DETERMINATION OF HARM TO WATER BIOLOGICAL RESOURCES

abstract 1291705046 issue 129 pp. 563 – 588 31.05.2017 ru 22
The article gives the description and the algorithm of the simulation model SMDS "Potok" 1.0, designed to calculate the parameters of distribution and sedimentation of technological alluviums in watercourses. The relevance of the simulation model is due to the need to determine the integral indicators (the volume of water flowing through the areas of the plume with a predetermined suspension concentration, the average layer of the silt, the specific density of the bottom silt in the calculated zone) when calculating the harm to water biological resources from the implementation of various economic activities in accordance with the methodology of calculation of damage caused to water biological resources approved by the order of the Federal Agency for Fisheries No. 1166 of 25.11.2011. Usage of the simulation model of SMDS "Potok" 1.0 will increase the reliability of calculations in determining the damage to water biological resources, as well as bring the calculations of parameters of distribution and sedimentation of technological alluviums in watercourses in accordance with the current regulatory legal acts of the Federal Agency for Fisheries

BIOLOGY OF SEED GERMINATION OF SOME SPECIES OF FAM. ROSACEAE JUSS

abstract 1291705016 issue 129 pp. 199 – 207 31.05.2017 ru 13
We have studied the germination and the nature of germination of seeds of 20 species of FAM. Rosaceae. A wide range of germination characterizes their seeds: rapid, slow, with very poor or no germination. Laboratory germination of seeds stored at room temperature for 6-7 months have 80-100% - 8 species, 66-77% - 3, 1-9% - 4 species and 5 species did not germinate at room temperature, they need special conditions for germination

FEATURES OF THE ASSIMILATION APPARATUS FORMATION OF WOODY PLANTS IN THE CONDITIONS OF THE LIPETSK INDUSTRIAL CENTER

abstract 1281704022 issue 128 pp. 319 – 329 28.04.2017 ru 106
The article presents data on the growth of an assimilation apparatus of Scots pine, silver birch and pedunculate oak in the conditions of the Lipetsk industrial center. It is established that the growth dynamics of annual and biennial needles of Scots pine under pollution is higher compared to the control, while absolute values of length and mass of needles less. Starting from the second year, in the conditions of contamination noted stunted pine needle growth, which increases by the third year. It is shown that the linear dimensions of the lamina of birch in the conditions of pollution are not changing much compared to the control, whereas the linear dimensions of the lamina of pedunculate oak in the conditions of pollution is less than the control
