Different aspects of applying the pollen analysis were studied in plant breeding. Fertility, pollen viability, change of pollen morphological characteristic were used by basic characteristics. Connection between pollen analysis and plant reproduction potential have been analyzed
The immunologic characteristics of 18 domestic winter wheat cultivars to Transcaucasia population of yellow rust pathogen have been studied. 251 resistance sources to Puccinia striiformis have been detected among 468 studied soft wheat samples from Vavilov ARRIP collection. The efficiency of known resistance genes (Yr) to Transcaucasia population of yellow rust pathogen are estimated
The dynamics of closed wood coniferous and deciduous forest formations for the last 15 years are presented
Qualitative and quantitative composition of the low-molecular carboxylic acids (CA) which were contained in the cultural liquid (CL) of the four strains of Escherichia coli and Salmonella enteritidis var.Issatchenko was investigated. The differences in the composition of the CA were shown, their dynamics during the bacterial growth and their total concentration in CL were strain specific characteristic. The differences in the composition and dynamics of the CA, which are specific only to probiotic and opportunistic strains were revealed
The process of drying of a corrugated cardboard is described and the mathematical model is resulted in this article. Questions of use of the received model are considered at process research
The zone of attraction of hauling branches in an allocation scheme based on the roads in "herringbone" forest resources is divided into 'near' and 'distant' parts with respect to location of contiguity point to forest road. In the "distant" part at certain parameters of cutting area, it is advisable to lay spar roads to a branch at an angle equal to the optimal angle of junction of branch to line, which reduces the cost of removal of wood on the branch. In the "near" part, as well as in forked and combined schemes of road allocation in forest resources , spar roads should be run under the best angles determined by established analytical relationship to reduce the cost of removal of wood
This article develops mathematical, software and technical support for design of extreme control systems growing for planting of seedlings in hothouses
In the article, the material of the new technology and means for processing of seeds of the coniferous breeds used in silvicultural manufacture at restoration of woods is presented
In the article, the way to solve the problem of use of energy of a waste waterway for the purpose of reception of the additional electric power, taking into account ecological factors, is offered. The offered way consists in application of the developed design of hydroelectric power station
This article analyzes the boundary problem model of transport of binary electrolyte membrane systems in the approximation of Ohm's law. Different methods of solution are proposed
