Dry seeds of seven winter wheat varieties and one line were exposed by gamma-rays and chemical mutagens to determine their effect on plant grows and development. Next parameters have been investigated - plant survival, pollen fertility, components of yield structure. Informative value by mutation depression evaluation of all parameters has been developed. The most informative parameters for mutagenic depression in M1 generation of winter wheat plants were survival of plants, pollen fertility, indicators such yield structure parameters as plant height, grain weight per spike, thousand grains weight. Insensitive and most sensitive for mutagen actions varieties have been developed.

[Figure not available: see fulltext.] Arylglyoxal hydrates interact with N-alkoxyureas and N-hydroxyurea in acetic acid with selective formation of 3-alkoxy-5-arylimidazolidine-2,4-diones and 5-aryl-3-hydroxyimidazolidine-2,4-diones, respectively. The structures of 3-methoxy-5-phenylimidazolidine-2,4-dione, 3-ethoxy-5-phenylimidazolidine-2,4-dione, and 3-butoxy-5-(4-chlorophenyl)imidazolidine-2,4-dione were studied by X-ray structural analysis. © 2015 Springer Science+Business Media New York.

The soil airborn pollution influence on functional state of radish seedlings was studied. It has been shown, that the variability of chemical composition of soils from different polluted sites lead to active reorganization in cell protein system. Comparative analysis of obtained data allows to reveal a direct correlation between the degree of contamination and the mass escape. Reduced mass escape of soils in Dnepropetrovsk was 15-21% for Dneprodzerzhinsk 25-45%. To a certain extent, changes in protein concentrations in the roots and leaves are in inverse proportion to the mass of escape. The biotesting of airborn polluted soils in Dnipropetrovsk and Dniprodzerzhynsk cities has been done. It was established that radish as plant bioindicator adaptive reactions to heavy metals pollution are connected with decreasing of intensity of general protein synthesis, the formation of different in the composition and intensity of pool readily soluble cytoplasm inclusion proteins, the changing in activity of antioxidant protection system. The activity of peroxidase determined in roots and leaves of radish sprouts varies considerably. That is caused by the nonuniformity of the composition in investigated sites. © 2015 Vasile Goldis University Press.

Atmospheric pollution in Ukrainian industrial cities poses a serious environmental threat. Intensive mining and industrial activities, power and heating plants, construction enterprises, have contributed to increase in the number of atmospheric pollution sources.The purpose of our study is to estimate pollution with NO2 and SO2 in Dnipropetrovsk region. Assessment of air pollution with NO2 and SO2 is carried out using the new GIS system and weather data from stationary networks of Dnipropetrovsk Hydrometeorological Regional Center. Elevated concentrations of nitrogen dioxide (excess of Maximum Permissible Concentration in 1,25-2,25 times) is observed during last 5 years in the atmosphere of this region. Atmospheric pollution estimated above average according to accepted gradation of air pollution index. Interpolation of three-year data from monitoring stations in the above two industrial cities has allowed to build the map to assess the level of atmosphere contamination risk with nitrogen and sulfur dioxide (individually and collectively). In terms of total soil pollution with heavy metals near the metallurgical plant are rated as "moderately threatening". Bioassay of soils technogenic pollution revealed weight decrease of 4-days radish sprouts from 15 to 45%. © 2015 Vasile Goldis University Press.

The article describes the distribution of areas of Scots pine (Pinus sylvestris Linnaeus) and Black locust (Robinia pseudoacacia Linnaeus) stands within the Northern Steppe of Ukraine based on forest biometry data. The total area of Scots pine stands is 21,472.9 ha, of Black locust it is 17,683.7 ha, which corresponds to 24.6 and 26.9% of the total forest-covered area. Scots pine is partly naturally, partly artificially regenerated. Black locust stands are man-made forests only. Both species form mainly pure stands within the study area. Mean age of Scots pine is around 60 years with a mean wood stock of 292 m3·ha-1. The dominant Black locust stands are overmature ones with a mean age of 43 years and a mean stock of 149 m3·ha-1. Generally, for both species, an increase in mean wood stock was observed, reaching its maximum at 71 to 75 (Scots pine) and 81-85 (Black locust) years of age. It has been demonstrated that the largest area of Black locust stands is represented by relatively rich soil conditions (54.3%), whereas in Scots pine stands there are relatively poor soils (56.5%). © 2016, Czech Academy of Agricultural Sciences.

This research is dedicated to identifying of misbalances on the agrarian market of Ukraine in the areas of grain, vegetable, fruits and berries, meat, milk and egg production. The analysis of their demand and supply dependence during the 2007-2014 period was conducted by means of coefficients of correlation, limit effectiveness and elasticity. It is determined that volumes of production are more sensitive to consumption levels. The worst misbalances are related to meat, fruits and berries, where production does not cover even the limited solvency of the Ukrainian population. Consumption has the greatest impact on vegetable production in crops-growing and meat production in animal-breeding. The stimulation of production development by the price factor is considered by types of agricultural holdings. According to calculations, the increase of wages in agriculture caused the growth of grain and meat production. Growing incomes allowed the population to substitute the consumption of bread with a more useful consumption of vegetables, fruits and berries. However, the consumption levels for fruits and berries, meat and milk in Ukraine do not correspond to the international nutrition standards. It has been found out that the consumer price index demonstrates the strongest correlation with egg consumption, whereas the worst situation is observed regarding the demand for milk. The obtained results are the basis for further development of the mechanisms for addressing imbalances in various branches of the Ukrainian agriculture. © Institute of Society Transformation, 2015.

A mechanism of preparing rationalistic solutions in the system of distributing logistics of a fruit and vegetable cooperative has been studied considering possible alternatives and existing limitations. Belonging of separate operations of the fruit and vegetable cooperative to technological, logistical or marketing business processes has been identified. Expediency of the integrated use of logistical concept DRP, decision tree method and linear programming in management of the cooperative has been grounded. The model for preparing decisions on organizing sales of vegetables and fruit which is focused on minimization of costs of cooperative services and maximization of profits for members of the cooperation has been developed. The necessity to consider integrated model of differentiation on levels of post gathering processing and logistical service has been revealed. Methodology of representation in the economical-mathematical model of probabilities in the tree of decisions concerning the expected amount of sales and margin for members of the cooperative using different channels has been processed. A formula which enables scientists to describe limitations in linear programming concerning critical duration of providing harvest of vegetables and fruit after gathering towards a customer has been suggested. © 2014 The Authors.
