Results of calculations of expenses for reproduction of yellow ferrsialit Republic Abkhazia soils are resulted. The necessary quantity of organic substance and an expense of anthropogenous energy for increase in the maintenance of a humus in sredne-loamy yellow ferrsialit soils is calculated. Influence of various basic processings of soil on humus distribution on a soil profile is revealed and the optimal are defined for processing downslope soils under a bookmark of citron plantations.

On bases of an analytical review of problems related to the production of biofuel the most feasible ways of further development of this business has been outlined. Socio-economic and agronomic aspects of the biofuel production have been analysed. Alternative cultivars were grouped according to their suitability for production of bioethanol, biodiesel, or biogas. Engagement of the local population in green biomass production and processing it for biofuel may help India to solve its food, energy, environment and social problems.

The data obtained during screening among several plant species from three different families are present here. It was shown that in seedling stage all of three species (common ice plant, rape and vica) were characterized as relatively high tolerant plants when incubated under excess copper. All of investigated species could be recommended as highly effective phytoremediators for territories with medium to high level of toxic metals.

The effects of cold stress on contents of proline, malondialdehyde (MDA), soluble sugars, enzyme activity of Superoxide Dismutase (SOD) and peroxidase investigated in transgenic rapeseed plants (Brassica napus L.) which contain gene OsMyb4 and non-transgenic plants. Under the cold stress sugar content in transgenic plants was significantly lower than in non-transformed, however the proline content was higher. MDA content was increased in non-transgenic plants and was decreased in the transgenic. That the change in the activity of the SOD enzyme in the both lines of the plants was similar, and peroxidase activity for 2 days under cold stress in non-transgenic plants increased, remaining constant at the transgenic, but in 5 days decreased in both lines of plants. After the return of plants to +24 °C, all parameters in all plant lines returned to normal. According to the results of experiments suggests that the kind of protein content for expressing transgenic plants OSMYB4 affects the other genes, low and high expression.

The work presents clarification of some pathological changes and development of diagnostic techniques for craniovertebral anomalies, as well as creation of an algorithm for identification of physiological norm and pathology of craniovertebral area in miniature dog breeds. As a result an algorithm for evaluation of the extent of pathology in craniovertebral area based on cranio- and encephalometric method was developed. Indices of relevant values are provided, which allows unifying data from radiography and tomography, and carrying out precise diagnostics in spite of substantial differences in anatomical structure of cranium in different dog breeds.
