The research results on the composition of the fatty acid of the bud meristem neutral lipids of Larix sibirica L. in winter in the meristem low thermal resistance conditions and in spring in the loss of stability to low temperatures are presented. It is shown that the change of tree phonological condition in the transition from the rest to vegetation is accompanied by the significant change in the fatty acid composition of the living tissue neutral lipids and unsaturated fatty acids.
