ISSR ANALYSIS OF PINUS SYLVESTRIS TREES APPURTENANT TO DIFFERENT SELECTION CATEGORIES
Description
The genetic variability study of Pinus sylvestris trees appurtenant to different selection categories in the plus stand is carried out with ISSR markers. A total of 178 loci were amplified by 6 ISSR – primers and 168 of them were polymorphic. It is detected that the genetic distance between the trees appurtenant to difference selection categories varies from 0,038 to 0,082. Genetic variation parameters of the Pinus sylvestris plus stand are calculated. Shannon’s index (I) was 0,4303, Nei’s gene diversity (H) was 0,2735 and Effective number of alleles (Ne) was 1.4268

AUTOMATION OF THE FELLING HEAD OF A FOREST MACHINE
Description
The article presents a brand new approach to the issue of automation of a workflow of the felling head to retain the truncated tree in an upright position when it is carried out of the woods. The model of holding tree upright and a block diagram of the position control of the felling head have been presented

АPIINDICATION AS A PART OF RADIOECOLOGICAL MONITORING
Description
The opportunity to apply products of beekeeping to the environmental control of territories polluted with radionuclides is examined
-
Description
The researches have been conducted for the optimization of culture medium for unique genotipes of Populus tremula L. in vitro. It was found that for induction of proliferation of the arms of Populus tremula in vitro one should use MS culture medium with 0,1 ml / l IBA and 0,1 or 0,5 ml / l BAP. For stimulation of rhizogenesis MS culture medium with 0,3 ml / l IBA should be used

EFFECT OF NON-TRADITIONAL MELIORANTS ON THE MICROBIOLOGICAL ACTIVITY OF SOIL AND GROWTH OF PLANTS
Description
The effect of the new meliorants on the qualitative and quantitative composition of the microflora of loamy sand soil and the growth of pine seedlings is presented. The activization of microbiological processes and growth of plants on the meliorated plots is revealed

EFFECT OF SOIL AND ECOLOGICAL CONDITIONS ON THE GROWTH OF SEEDLINGS OF PINUS SYLVESTRIS
Description
The influence of agrochemical and physical properties of a soil on the growth of the seedlings of Pinus sylvestris in the forest nurseries in Chuvash Republic is studied. The correlations of the growth of the seedlings and agrochemical and physical properties of the soil are simulated
