IMPACT OF GROWTH REGULATORS WHICH WERE NOT USED EARLIER IN CLONAL MICROPROPAGACTION ON MICROSHOOTS OF PLUM IN VITRO

abstract 1151601065 issue 115 pp. 1038 – 1045 27.01.2016 ru 868
The article presents results of the assessment of the efficiency of non-hormonal preparations which were not earlier applied in culture in vitro with high physiological activity (the preparations received by production of furfural, and also derivatives and compositions of organic acids) during regenerations of microshoots of plum, comparison of their influence with influence of growth regulators which are traditionally used in clonal micropropagation. These experimental preparations were received when processing waste of agricultural production. In this work we used: technology of clonal micropropagation of plants of in vitro, statistical data processing by method of the dispersive analysis. The objects of researches were microshoots of plum of a Stanley variety. We have established that on mediums with the preparations "Universal", sodium succinate, potassium succinate, amber acid, L-1 the large, intensively colored plum microshoots develop surpassing control (medium with BAP of 1 mg/l, IBA of 0,1 mg/l, gibberellic acid of 0,5 mg/l) in morphometric parameters. Thus, the preparations "Universal", sodium succinate, potassium succinate, amber acid, L-1 in concentration of 4,0 mg/l proved as the growth factors which are favorably influencing on plantlets’ regeneration and a qualitative condition of microshoots of plum

IMPACT OF WAYS OF INCORPORATING RICE STRAW INTO THE SOIL ON RICE YIELD

abstract 1341710051 issue 134 pp. 650 – 660 29.12.2017 ru 311
In the conditions of the two-factor field experiment, the influence of four methods of incorporating straw in the soil on the rice yield was studied: plowing, one-, two- and three-time discs and three ways of "processing" the straw: embedding in the soil of the chopped straw in its pure form, together with compensating nitrogen fertilizer and inoculated stubble biodestructor Stemix ® Niva. It is shown that the lowest yield is formed when straw is plowed, while surface tillage of soil by one-, two- and three-fold discs significantly increases the grain yield in comparison with the plow by 2.4, 4.2 and 5.2 c / ha, respectively. Taking into account that the double disking provided an almost twice increase in the yield of the crop and the absence of statistically significant differences with the triple disking; it is this method of incorporating the straw that should be considered the most expedient. The introduction of a compensating nitrogen fertilizer ensured a reliable increase in yield by 5.1 and 3.7 centners per hectare in comparison with the variants with the introduction of straw in pure form and treatment with biopreparation. Calculation of the share of the influence of the factors studied on the rice yield showed that the method for embedding straw provides 29.9% of the variability of the trait under study, the method of straw treatment is 36.7%, and the residual dispersion accounts for 33.4%. Incorporation of chopped rice straw in the soil together with compensating nitrogen fertilizer in the amount of 1% of the mass of straw, by double discing, ensured the receipt of a conventionally net income of 6940 rubles / ha, the rate of return - 70.4% and the cost recovery - 1.7 rubles / rub

IMPLEMENTATION OF POTENTIAL PRODUCTIVITY OF THE OLD VARIETIES OF WINTER WHEAT

abstract 1151601051 issue 115 pp. 829 – 848 27.01.2016 ru 541
In the article, we discuss issues of morphological and physiological control over plants of winter wheat. As the object of the research, we have selected landraces - the population of winter wheat, which was grown on the territory of the Kuban region in the last century. The aim of this work was determination of the effect on the reproductive system of winter wheat varieties of factors such as conditions of cultivation and processing "Cecece 750" 1.5 l/ha D. V. crop retardant. To achieve this goal we have conducted a morphological analysis of the growth cone at the VI stage of organogenesis, which provide quantitative evaluation of potential future seed production of spike of winter wheat. To study the effect of the year of breeding on the reproductive system of winter wheat varieties the analysis of variance was calculated according to the scheme 3×7 factorial variability characteristic due to the influence of genotype (factor B), cultivation year (factor A), that is repeated in time is interpreted as the effect of the year conditions of cultivation. The influence of retardant on the reproductive system of winter wheat varieties was conducted using the analysis of variance on the above described scheme, 2×7, where the factor "A" is presented in two gradations (options, retardant treated and not treated), in this case, repeated for years was excluded as a factor. The result of researches indicates that the rate of realized productivity is variety-specific and can serve as a measure of the flexibility of the studied cultivars to different environmental conditions. The analysis of variance showed significant retardant effect on the realization of potential productivity in all variants of the crops of soft winter wheat. The comparison of the average general population indicates that the genetic potential of tall varieties may not manifest even in favorable for crop cultivation. The artificial reduction of plant height by inhibiting the growth of retardant is an effective way to identify high productivity of these genotypes as varieties of winter and Nemenchinskaya Old No. 346

IMPORTANCE OF MICROORGANISMS IN THE FORMATION OF COMPOUND COMPOST

abstract 0961402025 issue 96 pp. 335 – 361 28.02.2014 ru 1202
Formation of the compound compost is due to com-pounds of mineral and organic colloids, creating new cycles biogens, enhancing the enzymatic activity of or-ganic matter, respiration of living organisms, the occur-rence of gaseous compounds, especially nitrogen, ex-panding ecological niches. Number of microbial com-munities evaluates the level transformation of organic matter, the activity life-support systems of living organ-isms. Introduction of complex compost to the soil en-hances of possibilities of ecological niches

IMPROVEMENT OF SEED CROPS IN THE KRASNODAR REGION

abstract 1151601056 issue 115 pp. 894 – 907 27.01.2016 ru 738
The main detected problems in selection system and seed industry consist of depreciation of laboratory equipment and specialized technique; the lack of funds and low incentives for creators of sorts; decreasing of volumes of elite and original seeds production in the Krasnodar region; common use of low reproduction seeds in production of grain. The existing stairs of seed multiplication system are examined, as well as their organizational and legal status. Directions of improvement of system of state support in this field are defined on the basis of presenting subsidies and preferences on purchasing of import of highly specialized equipment, provided that there are no domestic equivalent; correction of requirements in order of receipt of support for development of elite and original seed industry. The necessity of creation of united seed selection center of seed industry in the Krasnodar region on the basis of a specialized research Institute (KNISH of Lukyanenko). Though, as the result of providing by center of consistent recommendations on peculiarities of cultivation of sorts and their adaptive placement, maintenance of contractual relations based on principals of franchising, evaluation of sort and sowing index of quality of seed lots and hybrids, will allow to speed up the development of domestic seed industry, increase the quality of corn farming in region
