SMALL-LEAVED LIME (TILIA CORDATA) CULTIVATION IN THE OMSK REGION SOUTH FOREST-STEPPE CONDITIONS
06.00.00 Agricultural sciences
DescriptionSmall-leaved lime (Tília cordata) is wonderful species of trees, producing honey. This tree species is not cultivated in forest tree nurseries of Head forestry department of the Omsk region for the purpose of an artificial reproduction. Small-leaved lime grows wild in Bolshyi Uki, Ust-Ishym and Tevris areas. This forest is the basis for a honey production. Small-leaved lime occupies a very small area, which equals 1,5 ha. Natural reproduction of small-leaved lime in the Omsk Pryirtysh district is a reliquiae. Questions of reproduction of small-leaved lime have not been studied yet. Shoots cloning of small-leaved lime has an important practical value for areas of natural reproduction. A technology of seed reproduction has not been developed for the Omsk region. Complexity of the matter is in the existence of a long and deep physiological quiescent period of small-leaved lime seeds. Experimental facts of small-leaved lime seed reproduction has been described in this article. Results of measuring of height and root neck diameter of oneand two-year old plants have been shown. The influence of putting young plants in the shadow on their growth and development has been evaluated. It has been shown that seedlings received from small-leaved lime growing in the Оmsk State Agrarian University Dendrology Park have large variation in the growth and development parameters and the fact of casting shadows on the plants truly affects the height of oneand same as two-year old samples

CULTIVATION OF RIСE IN CONDITION OF SALINITY WITH APPLICATION OF GROWTH REGULATORS
06.00.00 Agricultural sciences
DescriptionIn the course of research the impact of polymeric pellicle-forming growth regulators (PGR) on the growth and development of rice plants while cultivated in conditions of salinity has been studied. It was ascertained that preseeding PGR treatment of seeds at the rate of 10 liters of solution for 1 (one) ton of seeds boosts germination energy, germinating ability of seeds, sprouts, length gets extended and weight enlarged. PGR lead to increase of electrochemical gradient on the membranes of chloroplasts, tilacoids and acceleration of electrons transport between I and II photo systems. PGR diminish toxicity of salinity which is fixed in parameters measured in experiments that are close to the control values. PGR application improves parameters of the structure of rice crop cultivated in conditions of salinity.

PLANT HEIGHT AND LODGING RESISTANCE OF COLLECTION VARIETIES OF WINTER BARLEY
06.00.00 Agricultural sciences
DescriptionLodging resistant is a very important factor of limitation of the yield of barley. The yield of lodged crops may be decreased up to 50%. The quality of the yield also deteriorates which negatively affects brewery characteristics. The lodging resistance of a variety is determined genetically and depends on a plant height and weather conditions during dynamic vegetation. One of the main aims of breeding of the crop for lodging resistance is the selection of short-stem varieties. However, a thorough study of the basic material and determination of its adaptability to a particular soil and climatic zone and suitability of its usage as parental forms are needed. The article covers the plant height of collection varieties of winter barley in the central zone of Krasnodar region and determines the groups of the varieties based on this trait. The dynamic of plant height formation depending on the vegetative conditions during five years is studied. The examination of lodging resistance of winter barley revealed that there are many non-lodging forms of the crop. New local varieties and lines have short and strong culms. Also, some varieties from Western Europe and the USA show its good lodging resistance under these conditions

HEMATOLOGICAL PARAMETERS OF PIGS WHEN USING YAKON TUBERS AND ADSORBENTS IN RATIONS
06.00.00 Agricultural sciences
DescriptionUnder the current conditions, it is very important to boost the production of pork and improve its sanitary and hygienic quality for the successful handling of problems subjected to import substitution of meat products. This can be reached by means of strengthening of food reserve. For that purposes, in the frame of two experiments yacon tubers in combination with enzymatic agent protosubtilin GZx have been introduced in the intakes of fattening pork stores instead of fodder beat, and various doses of carbitox adsorbent have been additionally added when superfluous background of heavy metals was observed. During the 1st experiment, the substitution of fodder beet with the similar quantity of yacon tubers has allowed the animals of experimental group to outweigh the ones from the control group on 7,5% in the terms of gross formation of body weight, and to gain 100 kg of body weight for 7 days ahead of the animals from control group as well. Additionally, fodder costs per product have been reduced and the morphological and biochemical values of animals blood have been optimized. Based on the data from 2 nd experiment, it has been defined that the better dose for feeding of adsorbent carbitox was 2,0 kg per tonne of concentrates thereby the animals of 3rd experimental group had reasonably higher body weight gain and thereby higher feed-conversion ratio by products. Therewith, the animals intermediary metabolism has been speeded up due to optimization of morphological and biochemical values of blood and reduction of heavy metals content in blood serum, in other words level of zinc, lead and cadmium was not exceeding maximum allowable concentration

GENETIC METHODS OF AUTOPOLYPLOIDY OF GRAPES
06.00.00 Agricultural sciences
DescriptionThere are materials about different genetic methods of metotical and meyotic autopolyploid of grapes in the article. Main morphodiagnostical signs of autopolyploids in it are pointed. New forms and varieties of grape may easily form with the help of genomic mutation. The experimental polyploid on grape leads to functional changes, which helps to become aliveness and stable in bad environment. The increasing of such kind of main genetic signs in grape, as high stable to bad ecological facts, illness and insects, high growing, seedless, high productive from bush, becoming sugar gather in fruits and bioactive elements in juice, etc., so it is possible to solve it only in moving to the new level of ploidy

GENETIC PECULIARITIES OF SYMMENTAL LIVESTOCK DROPPED OFF INTO FARMS OF THE KRASNODAR REGION
06.00.00 Agricultural sciences
DescriptionFarms of Krasnodar region purchase cattle of milk, combined and meat direction of productivity. Imported cattle are accompanied with documents which differ from analogous ones specified in such cases by pedigree service of Russia. There were studied 1000 heads of symmental cattle of milk-meat direction of productivity imported from Austria. More than 5000 kg of milk can be obtained from cattle of symmental breed of milk-meat direction of productivity, except it they show enough high meat productivity. The analysis of accompanying documents on purchased cattle is joined not only with language barrier but with the lack of knowledge of adopted abbreviations, contractions and other attributes used by foreign breeders abroad. Having studied the accompanying documents connected with hereditary information of purchased cattle there was determined that imported heifers and their mothers were obtained in Austria, and mothers of bulls on 55,5% obtained in Austria and 41,6% in Germany. So, on formation of imported micropopulation of cattle greatly influenced the breeding school of Germany. In accordance with the adopted classification in Austria due to revealed cases of adoption of Holstein blood, there is a ground to consider the present herd as a belonging to the group of pure breed of symmental cattle and in prospect to conduct the mating of cattle with pure breed symmental oxen with the aim of absorption of mixtures of Holstein blood in pedigree. The researches determined that one can purchase the producers with characteristics of milk productivity at daughters of oxen not lower than Austrian indexes on voluminous milking and German – on milk quality, the purchase of symmental cattle from other countries must be subjected to this demand.

DescriptionHybridization was performed for nine hybrid combinations between Russian early-ripening varieties Novator and Serpantin and South Korean cold-tolerant introduced samples Odaebueo и Tinbubueo. As a result, 283 hybrid caryopses in eight combinations were obtained, which were later studied in growing conditions. Study of trait inheritance in F1 hybrids was conducted, heterosis effect of studied hybrid populations was determined by productivity and individual elements of yield structure, using indicators of the degree of phenotypic dominance (hp) of quantitative traits. Significant variability in agronomic traits of F1 hybrids was determined. The manifestation of heterosis in productivity was noted in combination Odaebueo / Tinbubueo, in which super dominance was observed by all the studied traits forming productivity, in the hybrid progeny. Using the "halves method", analysis for cold resistance of 227 F2 plants in eight hybrid populations was performed. Seven lines with increased resistance to low positive temperatures during germination were identified in five hybrid combinations, which is 3% of the studied material. It is shown that in breeding for cold resistance as mother plants in hybridization it is necessary to use rice varieties (samples) that are resistant to low positive temperatures during germination, and as paternal - more productive varieties, adapted to soil and climatic conditions of rice growing area of the Krasnodar Region
