In article the modern condition of plant growing in Republic Guinea-Bissau is considered. The plant growing place in a national economy is considered also. Security is analyzed by the basic resources. The analysis of manufacture of the basic agricultural crops becomes, their productivity and areas under crops in 2000-2006 export and import of production of plant growing are considered.

We have examined the seeds of 12 species of Bauhinia L. genus. We have proposed numeral signs of seed macrostructure. We have shown that they can be divided into two groups according to self-evident signs of seed macro- and ultrastructure. The obtained data can be used for classification of the genus.

Different strains of antagonistic bacteria and fungi have been actively tested for the last several years in order to discover their complex fungicidal , bactericidal and nematicidal activity in different plant communities and regions of Russia. This work is targeted for elaboration of environmentally friendly and energy-saving methods of plant protection. Bacterial strains of Pseudomonas and Bacillus, that possess not only fungicidal but also bactericidal and nematicidal effects, were revealed in the results of pot, laboratory and field experiments. These strains could regulate the number of virus-vector nematodes of Longidoridae and Trichodoridae and their associated viruses. Also, the strains could be shown to stimulate plant growth and high yield of different varieties of test-plants. They should be considered to be the natural regulators of the quantity and the distribution of parasites. This work was supported by grant RFFI 05-04-49237.

The following research is devoted to the study of the morphological and biochemical features of blood under conditions of hypovolemia due to multiple traumas of the pelvic limbs in dogs. The correlation between the changes of the structure of the erythrocytes under conditions of infringement of metabolism, tissue disintegration and redistribution of fluids and the biochemical indicators of the blood serum, which characterize the emunctory capability of the kidneys under conditions of hypoxia of the organ, was detected. A systemic approach has been presented in the article to the study of the processes occurring in the organism of dogs under the influence of posttraumatic hypovolemia. An exploration of the dynamics of the biochemical and hematological changes in the organism were carried out, giving the characteristics of the changes of the erythrocytes in the acute posttraumatic period. The dependency of the structural characteristics of erythrocytes from the degree of diminution of the volume of the circulating blood and the level of certain metabolites of the blood serum are presented. It has been established, that the development of prerenal insufficiency, which develops under acute hypovolemia, promotes the change in the structure and function of the erythrocytes, which, in turn aggravates hypoxia of tissues and organs.

Was made the research of the skin in 34 dogs at the age from the date of birth up to 10 years old (eight neonates, nine 3-4 months old puppies, eight 6-8 years old dogs and also nine 9-10 years old dogs). For the trials the specimens from different topographic and anatomical regions were selected and they were tested by histological methods according to the classical methods basing on the investigations made we can conclude that the skin is flexible and has high adaptive potentials. At the same time it has species specific features stipulated by the genetically fixed character of morphogenesis which determines construction peculiarities of the connective tissue in compliance with biomechanics requirements of the animal habitat.
