CENTURY-OLD SIBERIAN STONE PINE CROPS GROWTH AND PRODUCTIVITY IN THE ZONE OF CONIFEROUS-BROADLEAVED FORESTS OF THE MIDDLE VOLGA REGION

abstract 1311707097 issue 131 pp. 1168 – 1180 29.09.2017 ru 357
The purpose of the study was to examine a century of experience of growing of forest cultures of the Siberian stone pine in forest conditions in the region of the Middle Volga. To achieve these objectives, we have investigated old growth culture of Siberian stone pine in the conditions of fresh oak forests in the territory of Rootka forestry of the Mari El Republic. Culture of Siberian stone pine was planted after continuous tillage. The distance between rows was 2,5 m, step landing – 1,0 m. The site was divided into five options, depending on variations in the width of planting strip (I-48 m, II-44 m, in III-40 m, IV - 36 m, V - 32 m). The studies have shown that the Siberian stone pine trees, regardless of the variant, are characterized by good clean ability from twigs, which increases with decreasing of the width of the curtain. It can be noted that in the 100-year-old age, the average height of trees reaches of 28,7 m, an average diameter of 49,8 cm. Stock of forest reaches 795,3 m3 /ha. Best annual increase is observed in growing cultures of cedar in the wings with a width of 40 m and is 7,95-of 7,93 m3 /ha. Based оn the research, we have concluded that Siberian stone pine should be recommended for introduction into the zone of coniferous-broadleaved forests of the Middle Volga region. When creating crops, it is necessary to use larger seedlings and plant density is not more than 1,0 thousand pieces/ha, and the width of the planting strip shall be not less than 40,0 m.

CHARACTERISTICS OF ADAPTIVE TRAITS OF VARIETIES AND LINES OF WINTER (SOFT) WHEAT SOWN AFTER PEAS AS A PREDECESSOR

abstract 1111507076 issue 111 pp. 1191 – 1199 30.09.2015 ru 1063
The researchers of the institute are studying adaptive power of 17 varieties and 6 lines of winter wheat sown after peas using various methods of assessment of their adaptive properties. During the years of study (2012-2014) we found out that environmental conditions which account for 78% have the greatest effect on the trait ‘grain productivity’ in the formation of the yield. The share of genes accounts for 9,7%, the specific correlation ‘geno type x environment’ accounts for 10% which allow calculating adaptive properties. It has been defined that productivity of winter soft wheat changed a lot due to growing conditions and characteristics of varieties. The productivity ranged from 38,7 c/ha (‘Garant’ in 2014) to 76,5 c/ha 9’Lilit’ in 2013). The study found out that the varieties ‘Stanichnaya’, ‘Asket’ and ‘Lilit’ possess the highest response to cultivation with bi=1,15; bi=1,18 and bi=1,25 respectively. The varieties ‘Lilit’, ‘Krasa Dona’, the lines ‘430/07’, ‘260/09’ and 771/09’ possess a high adaptive ability and productivity with 111%, 105%, 108%, 105% and 106% respectively. The study of adaptive properties of winter soft wheat varieties gives an opportunity to distinguish adaptive, stress tolerant varieties with plasticity according to the primary structural elements which form productivity. The varieties ‘Asket’ and ‘Lidiya’ are characterized with high response to cultivation in different environmental conditions. The varieties ‘Lidiya’ and ‘Kapitan’ belong to adaptive cultivars. The varieties ‘Kapitan’, ‘Krasa Dona’ and the line ‘234/07’ are stress tolerant according to the trait ‘grain productivity’; the varieties ‘Kapitan’, ‘Krasa Dona’, ‘Lilit’ and the line ‘771/09’ are stress tolerant according to the trait ‘number of seeds per a ear’; the varieties ‘Lilit’, ‘Krasa Dona’ and the line ‘771/09’ are stress tolerant according to the trait ‘weight of seeds per a ear’

CHARACTERISTICS OF SUNFLOWER OPEN-POLLINATED VARIETIES FOR MAIN SEED TRAITS

abstract 1181604082 issue 118 pp. 1282 – 1292 29.04.2016 ru 773
Development of confectionery sunflower openpollinated varieties (OP-varieties) is a prospect direction in sunflower breeding. High price level for confectionery sunflower seeds pushes forward the breeding program. Contrary, it is necessary to offer product, meeting consumer’s expectation for large seeds, good dehulling rate, proper oil and husk content. The aim of our work is to study morphometric peculiarities of seed structure for sunflower OP-varieties of different types – oil and confectionery, and to identify the best samples for using in the breeding program as an initial material. The study was done at All-Russia Oil Crops Research Institute (VNIIMK) named by V.S. Pustovoit (Krasnodar) in 2014 and 2015. Seeds of 6 OP sunflower varieties of VNIIMK breeding were used as a material (confectionery type – Dzhinn, SPK, Lakomka, Oreshek, Borodinskiy and oil-type – Muster). OP-varieties were sown by randomized blocks with 3 replications. Every plot had 4 rows. It was shown that seeds of confectionery sunflower OP-varieties had higher values of main traits (length, width and thickness) in comparison with oil-type sunflower. Seed traits analyses allowed identifying the best confectionery samples (Dzhinn and Oreshek) for future breeding

CHEMICAL COMPOSITION COMPARISON OF DRIED TOBACCOS OBTAINED FROM DIFFERENT HYBRIDS, SORTS AND LINES

abstract 1281704068 issue 128 pp. 1003 – 1013 28.04.2017 ru 357
Tasting and smoking properties of tobacco products depend on chemical composition of dried tobacco. The most important are nicotine, carbohydrates, and proteins. Their content is controlled when new sorts are bred. In the article data on chemical composition and their analysis for some hybrids, new and zoned sorts are presented. Most of studied samples had medium nicotine content in dried tobacco. Hybrid of Jubileiniy noviy 142 and Ostrolist 46, sorts: Trapezond 159, 359, 115 and Ostrolist 46 were characterized as low nicotine tobaccos. Jubileiniy (standard) and Oktiabrskii were characterized as high nicotine tobaccos. This indicator depends on rain quantity during vegetation period. During drought seasons this indicator is higher. Total soluble carbohydrates content affects smoke taste. The more water soluble carbohydrates content the better smoking properties tobacco has. Unlike nicotine, carbohydrates content when rainy season increases. Best results were for Krupnolistniy 9M and Oktiabrskii. Proteins have negative effect on smoke taste as it becomes bitter and with smell of burned feathers. Most of studied hybrids have quite high protein content. For cured tobacco quality assessment, not total contents of proteins and carbohydrates are important but their ratio (carbohydrates/proteins) called Shmuk ratio. Best results were for Krupnolistniy 9M and Oktiabrskii

abstract 1071503108 issue 107 pp. 1661 – 1678 31.03.2015 ru 827
This article presents the results of the chick peas use instead of sunflower cake, in feeding young and adult livestock hens-layers of the cross "Hajseks brown". The researches were carried out in the JSC "Agrofirm Vostok" of the Nikolayevskiy district in the Volgograd region. The sunflower cake replacement with legumes - chickpeas as the part of the experimental animal fodder for young and adult livestock hens-layers had a positive influence on productivity, physiological state of the birds, product quality and economic performance. Chick peas’ use in young hens feeding improves live weight at 1.03-4.68%, egg production in 0.99-4.7%, the average weight in 0.99-3.75% and eggs quality indicators. Morphological and biochemical indices in experimental young hens and laying hens in all the groups were within the physiological range, indicating normally occurring redox processes in the body of a bird. However, the chick peas’ application in fodder for experimental young hens and laying hens contributed to the increase of total protein, calcium, phosphorus content in serum compared with counterparts in the control group that received sunflower cake. As the researches result, the economic effect in the experimental groups was 833.01-3821.87 rubles

abstract 1071503109 issue 107 pp. 1679 – 1692 31.03.2015 ru 884
This article presents the results of the chickpea effect in feeding young and adult laying hens of "Hajseks brown" cross on their productivity and nutrient digestibility of feed. Studies have been conducted on the JSC "Agro-firm Vostok" in Nikolayevsky district of the Volgograd region. Complete or partial replacement of sunflower oil cake by chickpeas as part of feed for the experimental pullet hens improves nutrient digestibility coefficients compared with the control pullet group. The balance of nitrogen was positive in all groups, the use of nitrogen taken from guinea pullets was higher than in the control group at 0, 27-0,74%. Use of chickpea in the composition of feed for laying hens increases the digestibility coefficients of nutrients: dry matter - to 1,17-3,25%, organic matter - to 1,62-3,37% crude protein - to 0,45-1, 77%, crude fiber - to 0,72-1,05%; crude fat - to 0,35-1,55%, compared with chickens, hens in the control group. The use of nitrogen from the digested was1,37-2,13% higher in the experimental groups compared to analogs of the control group. The use of calcium and phosphorus for the formation of eggs was also higher in the experimental groups
