Streak inoculation of microbial test-cultures was treated with volatile emissions of needles of 23-years clones of Pinus sylvestris L. The study was conducted in July 2011 on three test-objects - gram-positive bacteria Staphyllococcusepidermidis, gram-negative bacteria Esherichia coli and yeast-like fungi Candida albicans. Antimicrobial effect of pine volatile emissions was assessed in comparison with the control on 0 (absence of the effect) - 4 (strong effect) scale of antimicrobial activity. The mean marks of antimicrobial activity of clones, calculated in relation to separate test-systems, were within the limits of 0.00-3.00. The weak differentiation of pine clones to S. epidermidis is revealed. Frequency of pair comparisons in which statistically significant differences between clones was found to be less than 5 % for S. epidermidis and about 1.5 % for all the test-microbes. Alongside with it significant effects of the time of testing (calendar dates), a microbial species («pathogens) and interactions «date of testing-pathogens and «date of testing-clones were revealed: in ANOVA their effects amounted to nearly 23, 33 and 15 % of the total dispersion accordingly. The most probable reasons for it are dynamics of structure of essential oils and «genotype-environment interaction that should become object of future research. In this connection, an important question is what is the season that is optimum for reliable revealing of the pine genotypes with maximal antimicrobial activity? Negative between-clones (between-genotypes) correlations between antimicrobial activity to S. epidermidis and to C. albicans are revealed. It is probably caused by inversely proportional dependence between concentrations of the components in essential oils, which are responsible for inhibition of various pathogenic organisms. The sample of investigated clones was divided into two sub-samples that sufficiently differed by the levels of both antimicrobial activity to S. epidermidis and individual heterozygosity of allozymes loci. Such differentiation of genotypes is noted for the first time, and can be in focus of further studies.
