Populus tremula L. trees from aspen forest stand of “Molokcha botanical and entomological reserve” (Moscow Region) were studied. Trees were categorized into two groups - damaged and not damaged by rot. Average chronologies were constructed for them. Fourier analysis shows the presence of a clearly expressed cyclical component in the variability of the treering width with a period of 9.5 years. The analyzing the influence of climatic factors on radial increment formation in we can state that the most unfavorable impact on wood formation is caused by drought in the beginning of the vegetation period prior to the year of annual ring formation. There is a tendency of being less drought-resistant for diseased trees. The using of Pi-GC/MS method it allowed us to identify specific biochemical features of the wood of trees resistant to aspen tinder: a reduced concentration of polysaccharides and the presence of a synergistic group of lignin.
