Description
The possibility of the ISSR-markers application for systematization and genetic certification of the genus Rhododendron is showed on the basis the research of 25 species and intraspecific taxons. The way of recording of genetic passport on the basis of amplicons size is suggested

ISSR ANALYSIS OF PINUS SYLVESTRIS TREES APPURTENANT TO DIFFERENT SELECTION CATEGORIES
DescriptionThe 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

Description
In the article, we have studied the effect of lead contamination, an alternating magnetic field, their combination on such groups of soil microorganisms, as ammonifying, amylolytic, nitrogen-fixing bacteria, and micromycetes. The pollution had a significant and different effect on the number of soil microorganisms. The nature and extent of this effect varied depending on the level of impact of each factor, and they were not linear

MODELING MOISTURE DISTRIBUTION IN SIDE PERIODIC FLOODING OF SOIL-GROUND
DescriptionThis article describes how the periodic flooding of soil on a sandy soil model. It was established, that during the lateral movement of moistening of the soil, the moisture has a form of damped oscillations
