TEXTURE OF YOUNG PLANTED FOREST (PINE AND FIR SPECIES) IN MARI HIGH PLAINS AND ITS OPTIMIZATION
DescriptionDistribution peculiarities of planted Pine and Fir species (I and II age classes) in different sites of Mari high plains in accordance with their relative density and share of participation of target tree-species are described in this article. Based on the obtained data, some actions for enhancement of ecological and resource potential of the species are elaborated

DIAGEOTROPIC SHOOTS OF PERENNIAL GRASSES IN THE SOUTHERN REGIONS OF THE CIS
DescriptionStudying of perennial cereals of southern and boreal origin led to the allocation of plagiotropic shoots of rhizomes, stolons, that are placed in the soil or on the surface from the apical or lateral kidney of various structures with modified leaves, the beginnings of roots at nodes and developing of type kidney - lengthened shoots. Two types was allocated: type of solid finned cylinder and type of intermittent cylinder with scattered around the periphery of vascular bundles: first include cereals temperate regions and is characterized by separation from the epidermis continuous sclerenchyma ring, the second type (sorghum and millet) no continuous mechanical ring and vascular bundles relatively evenly spaced along the periphery of the shoots

SPECIES DIVERSITY OF LONG GOURD LAGENARIA SICERARIA (MOLINA) STANDL
DescriptionThe issues of international spread of fruits of long gourd lagenaria and the introduction of it in culture are considered in the article. We have shown how to use it as a vegetable crop and considered varietal diversity of this species. The biological characteristics of lagenaria cultivation as vegetable plants, including peculiarities of the reproductive system have been marked. We have also considered the issues of cultivation and distribution of long gourd lagenaria (zycca) for food

Description
The soil properties out of playing areas of golf courses (so-called roughs) have an influence on the lawn vegetation state. Heavy texture of the soil has the cause of deterioration of the water-air properties of soil which is accompanied by changes in the nature of addition grass lawn from solid to mosaic. Non-aggressive grass of the artificial lawn has one of the reasons for renewal of native flora and the formation of a new type of plant association, closer to the natural vegetation of the Don floodplain

FUNCTION FEED ADDITIVE OF CAROTE-NOID VEGETABLE RAW MATERIALS FOR POULTRY
DescriptionThe article is concerned with the use of functional feed additives from pumpkin fruits and alfalfa juice for the poultry industry. In the study of laying hen it has been found that the use of a feed additive in-creased pumpkin paste content in serum and egg yolk carotenoids is more than two times, and the concentration of vitamin A in these tissues increased slightly, not exceeding 20%. Livability and productivity of poultry increased and average expendable fodder per head per day decreased. Economic calculation showed that the use of pumpkin paste reduces the cost of production of eggs. The use of alfalfa juice coagulates in diets for broiler chickens resulted in an increase in the concentration of carotene in the liver by 22,7-46,8% relative to control. The juice addition also increased the content of vitamin A in the liver by 27.9%, increase the safety and efficiency of the bird. The authors draw certain conclusions from experiment results that the use of functional additives in poultry from the fruit of pumpkin and alfalfa juice is an alternative to synthetic vitamin preparations and produce a more environmentally friendly products

Description
The main contribution to the soil biological properties change in the combined pollution with lead and an alternating magnetic field makes lead pollution. Contribution of the interaction of factors of 20-30%. The contribution of the alternating field was insignificant or unreliable. Black soil and brown forest soils are similar in degree of resistance to the combined pollution. Grey sands have less stability

PLANTS AS AN ECOLOGICAL NICHE FOR HUMAN PATHOGENIC BACTERIA
DescriptionThe facts related to contamination of plants with pathogenic bacteria being a possible source of human foodborne intestinal diseases are discussed. Data bound up with influence of environment conditions with respect to attachment and penetration of bacteria in plant tissues are described. Exquisite results related to the rate of proliferation and the time of retaining enteropathogens in plant organisms are presented
