PROBLEMS OF DEVELOPMENT OF COM-POUND COMPOST
DescriptionCompound compost during its formation involving organic and mineral wastes retains the organic matter by reducing its degradation products with nitrifying and denitrifying organisms due to its economical ex-penditure of phosphorus and calcium, increased am-monia and total nitrogen, formation in the process of development of calcium sulfate with participation in its formation of residue calcium salt and ammonia

Description
This study was aimed on testing of IRAP markers developed at plum on varieties of peach, Russian plum and cherry plum and genotyping of home and foreign varieties of plum, followed by an analysis of the data. During the testing of the markers have been identified as a high level of polymorphism between genotypes of plum and between the studied species. On the basis of the results obtained by genotyping 15 samples of Prunus was built dendrogram. Cluster analysis was divided into 3 groups corresponding varieties of P. persica, P. domestica and a common group for varieties of Russian plum and cherry plum

ABIOTIC PECULIARITIES OF SMALL RIVERS OF THE STEPPE ZONE OF THE KRASNODAR REGION
DescriptionSteppe rivers (Eja, Beysug, Chelbas et al.) occupy a vast Azov-Kuban plain, whose total length reaches 4800 km and catchment area of the entire hydrological network of up to 24 000 km. Dams and silting increase flooding of agricultural land and many rivers severely degraded with a reduction of its water content and its quality. Landscapes of the steppe zone occupy a middle reaches of the largest rivers - Beysug River, Chelbas, Eja and differ of transaccumulative character and accompanied by numerous beams and small slope that prone to weak erosion. The valleys of the steppe rivers are characterized by high and gentle slopes and floodplains of river slightly wavy and their deep areas are swamped. As a parent rocks it is dominated by loess clay and clay. Features of soil cover are determined by topography. Black soils were formed on the plain, eroded and meadow-black soils are on the slopes, and meadow-bog soils - in areas with stagnant water. The climate is characterized by moderate winter and hot summers with insufficient moistened soil and low air humidity. The vegetation of the river systems of the steppe zone is divided into marsh, meadow, meadow-steppe vegetations and vegetations of saltmarshes. The ichthyofauna of small rivers is very scanty that is determined by the hydrological regime. Plowing of lands along the water bodies, the development of wind and water erosion is typical for steppe rivers; therefore siltation and overgrowing of rivers are widespread

ИНИЦИАЦИЯ ПРОЭМБРИОГЕННЫХ КЛЕТОЧНЫХ СУСПЕНЗИЙ У ДЕВЯТИ МЕЖВИДОВЫХ ГИБРИДОВ ВИНОГРАДA
DescriptionЧерешки листьев, взятых из растений ин витро, девяти межвидовых гибридов винограда: подвоев Берландиери х Рипариа ‘Кобер 5ББ’, Рипариа х Рупестрис ‘101-14’ и сортов (cvs): 'Бианка', 'Зигфридребе', 'Подарок Магарача’, ‘Первенец Магарача’, ‘Цитронный Магарача’, ‘Интервитис Магарача’ и гибридной формы ‘Магарач 100-74-1-5' культивировали на твердой среде NN, содержащей различные концентрации 2,4-D и BА в различных сочетаниях. Для того, чтобы инициировать рост клеточных суспензий, проэмбриогенные каллусы пересаживали в жидкую среду NN, дополненную 1.0 мг/л 2,4-Д и 0,2 мг/л BА. Субкультивирование этих суспензий в жидкую среду NN, дополненную 2 мг/л NAA и 0,1 мг/л BА, привело к развитию агрегатов эмбриоидов, а пересадка в жидкую среду с 0,5 мг/л BА вызвала развитие единичных глобулярных и сердцевидных эмбриоидов. Проэмбриогенные клеточные суспензии, состоящие из преимущественно отдельных клеток, могут быть использованы в трансформации генов и селекции на клеточном уровне с целью уменьшения вероятности появления химерных растений

EVALUATION OF SELECTION OF TREES OF SALIX ACUTIFOLIA WILLD
DescriptionIn order to identify high-genotypes in natural stands of Sacutifolia Willd we worked to identify the categories of breeding trees. Experimentally proved, that for breeding to increase the productivity of bark of Salixacutifolia Willd the selection would be best carried out with plants, the diameter of the barrel of which is in the range of 9 to 16 cm, tree age 15 - 19 years
