Extraction of the DNA from leaves of genus Vitis is a very difficult task, as a grape has a lot of elements, which make difficult to use it in the genetic manipulation. In that article used the methods of extraction of the DNA with silica (SiO2) particles as the absorbent material for getting better quality DNA
Criteria of an estimation and a condition of antierosion actions on various types of the agrolandscapes providing the termination or minimizing of erosive processes of soil and increase of productivity of erosioned unproductive soils are resulted in the article
Influence of system of the basic processing of soil and system of fertilizers of a sugar beet on accumulation of the general and productive stock of a moisture in the beginning and in the end of vegetation, total water consumption and water consumption factor, and also influence of these agro receptions on productivity and sugar content of root crops is studied
In this article, the analysis of thoroughbred sows of breed of Landrace and hybrid sows F1 in a combination (Yorkshire × Lanrace) on reproductive qualities and an index of commodity weight of a nest (ICWN-6) is presented. The economic benefit forecast is resulted at introduction system of hybridization with the use of imported breeds
In this article chemical and technical characteristics questions of vine materials, received from protoclones of grapes of Saperavi grade - one of the basic classical grades of grapes selected in "Pobeda" Joint-Stock Company are taken up. Samples of grapes have been used for preparation of red table wines by mash fermentation on septum in workshop of micro winemaking of The North Caucasian zone scientific research institute of gardening and wine growing. They have not given vine materials identical on physical and chemical and organoleptical features. Samples with low productivity essentially differed on organoleptical qualities from other samples and had the highest sampling estimations that allows to take measures on loading regulation on a grape bush and correct quality of wine in further by means of methods of agricultural technics. For making high-quality table red vine materials it is recommended to use apple-lactic fermentation by means of oxygen-eating bacteria
The analysis of frequency and distribution of chiasma of interspecific tomato F1 hybrids at meiosis prophase I was given. The character of synapsis in anther mother cells of interspecific tomato F1 hybrids was determined; the number of distal and interstitial chiasmata was calculated. The samples, recommended for their inclusion into the selection process as the inducer of genetic variability were chosen
The article presents the characteristics of the chemical composition of a complex of seven-resistant varieties, introduced in the Central zone of the Krasnodar region, and the quality produced from these natural clarified pasteurized juices, against three of the Eurasian, the control group. We recommend the most valuable varieties for production of high quality juices
The differences of phenotypes of perspective varieties of the apple-trees of Pinova and Honey Crisp and peculiarities of passing the main phenological phases of growth and development, relation to draught, amount and quality of crop yield with the regard to tree stock and conditions of growing were revealed in this research
The results of researches of influence of different irrigation modes on productivity of cultures and efficiency of use of irrigating water at cultivation of potatoes, cabbages, onions, tomatoes and cucumbers in the conditions of an irrigation are resulted in the article
Universal black-berry Apollo grape has been launched in Greece by P.Zamanidi, L.Troshin and A.Isachkin in 2003 with combinative selection - crossing of the Fi-lery Greek variety with the French Cabernet-Sauvignon. The duration of the production period 136-145 days. The strength of growth of arms is strong (2,1-3,0 m), the degree of maturation of the vines is high. Crop yields are very high - 35-40 t/ha. The aver-age mass of clusters is 430 g. It is characterized by high winter hardiness, drought-resistance and high resistance to fungal diseases in comparison with varie-ties of Vitis vinifera. The flower is bisexual. Cluster is big or very big, conical with the wing, loose. Berries are medium or large, oval, blue-black in color, with a thick wax coating. The skin is thick. The pulp and juice - with varietal flavor. Sugar content is high. Notable for long saving the harvest in the bushes, well-kept in the cooler cells. The variety is meant for the fresh consumption and for manufacture of red dry, desert and sweet wines; suitable for production of high-quality juices
