We studied the architecture of the root system of apple tree varieties (Idared, Golden Delicious, Rei-nette Simirenko, Florina grafted on the rootstock M9), planted in 2003, according to the scheme 4 x 1 and formed by type: Russian spindle (k) Knip Baum, Bee Baum, Sollux.
We found out that on mid loamy soil with drip irri-gation, the bulk of the roots located at a depth of 10 - 60 cm regardless of the type of crown formation. Large (more than 3 mm) roots of Reinette Simirenko and Florin varieties of trees in age of seven have penetrated to a depth of 60 - 80 cm while forming Russian spindle and Knip Baum crown-type and their length and their weight was
5 – 8% of the overall performance
The article presents the results obtained in experi-ments at the effect of the formation of crown of apple varieties, such as Idared, Golden Delicious, Florina and Reinette Simirenko on economic affect in Kuban region fruit zone. The estimation of different types of forming crowns is given. The best results were obtained in forming crowns in type of Bee Baum and Sollux for all varieties
New varieties of winter durum wheat selected by methods of complex crossing varieties of winter durum wheat of different ecological-geography region and their mutants differ with quality of grain adaptability to econiche. Value of chemical mutants in selection of winter durum wheat on adaptability and quality of grain is discussed
The inheritance of the “mass of 1000 grains” sign in the hybrids F1 and F2 was studied. Differences in the parental forms with 1-5 pairs of genes are revealed. The sources and the donors of the large-mass of grain are pointed, the indicative and genetic collections of the large-mass of grain forms of the grain sorghum are created
PHOTOSYNTHETIC ACTIVITY OF THE GRASS MIXTURE IN THE CONDITIONS OF THE RECULTIVATED ASH DISPOSAL AREA
The results of multi-years field study of the research of photosynthetic activity of Hungarian sainfoin + coach grass + awnless brome grass mixture in the conditions of the second recultivated section of ash disposal area of the Novocherkassk SDPP are reported
The crop productivity of peach varieties in different fruit zones of Krasnodar region was studied. The economic analysis of effectiveness of their growing was done. The practical recommendations on peach-tree gardens making were given by the results of five-year researches
Researches of improving of effectiveness of ways of fruit-tree stock rooting, stone cultivars of home and foreign selection were carried out at Krymsk experimental selection station. Reliable and effectiveness ways of reproduction of green and senescence cuttings were offered based on the results of this work. Stocks of stone cultivars for given systems of reproduction were allocated
The influence of peach-tree stocks on growth and development of different varieties in the conditions of Krymsk ESS (Krymsk) was studied. There were assessed the different parameters of growth and development of fruit trees. The most effective combinations of this culture were selected by the complex of economic signs
Researches on assessment of peach-tree stocks stability to soil pathogens (nematodes, fungi and bacterial diseases) and to the excess of lime and moisture as well were carried out in the conditions of scientific-industrial enterprises of Agromillora Cotalana (Spain). Adaptation level of studied stocks to marked stressors was determined upon the results of this work. The steadiest to them are allocated. Various parameters of grades of a peach in these conditions are estimated
The analysis of qualitative indicators of Don selected soybean varieties aimed to determine a possibility of their usage in processing industry is carried out. An evaluation of chemical and organic leptical indicators of soybean seed quality and physical properties is made. Possible directions of Don selected soybean varieties usage in processing industry are determined
