Аннотация: The results of the study of the qualitative composition and relative content of highly volatile compounds from the needles in two natural pine populations located in the forest-steppe zone in the south of Central Siberia are presented. Altogether, 89 components were isolated. Analysis of intra- and interpopulation variability of 31 terpenoids (mono- and sesquiterpene fractions) was conducted. The spatial structure of the variance of features was analyzed. Significant interpopulation differences in the content of most compounds were registered. It was determined that, as growing conditions deteriorate, the mass fraction of lighter monoterpene compounds (especially alpha-pinene) is increased within populations, and qualitative diversity of the components of essential oils is decreased. The groups of terpenoids, the relative content of which is to a different degree associated with interpopulation differences and variety of the growing conditions of trees within populations, were isolated.

Аннотация: Effect of tannin and non-volatile components of lesion resin on the growth of blue-stain fungi - Ceratocystis laricicola, C. polonica, Ophiostoma minus, Leptographium sp. and Ophiostoma sp. - the primary invaders of conifers in Siberia (Russia), has been studied. The fungi under study exhibited tolerance to plant's defensive substances in bioassays. The cultures of Leptographium sp., C. polonica, and Ophiostoma sp. proved to be the most tolerant to tannin. In the range between 0.05 and 0.15% tannin concentration their growth tended to stabilize. Less tolerant to tannin were C. laricicola and O. minus. With an increase in tannin concentration their biomass gradually decreased. The fungi more tolerant to tannin regulated the medium pH about 5.0 and higher, white the species which were less tolerant preferred lower pH values. Lesion resins of conifers differed in their inhibitory effect on fungal growth. Fir resin had the greatest inhibitory effect of all the conifer resins tested, causing reduction to 50-60% in fungal growth. When fungi were grown on the resin of any other conifer, the reduction in the linear growth rate did not exceed 20 to 30%. The assumption that fungi are more tolerant to the resin of a host plant than to that of a non-host plant has not been confirmed.

Аннотация: Intrapopulation diversity and correlations of 30 volatile compounds in needles have been studied in Scots pine populations of southern Siberia. Significant differences between populations have been revealed in the correlation pattern of relative terpenoid contents in needle samples. Stable combinations of closely associated mono- and sesquiterpenes and specific features of the general pattern of correlations between relevant characters have been determined.
