Abstract

The fatty-acid composition of Alchemilla subcrenata Buser has been identified. The peculiarities of adaptive changes in fatty acid content according to diel air temperature oscillations have been demonstrated. Augmentation of content of unsaturated fatty acid has been observed in the daytime, while growth of content of saturated fatty acid has been observed in the time of the night and in the evening. Analysis of activity of desaturazes demonstrates maximal contribution to development of low-temperature adaptation of Alchemilla subcrenata Buser is belonging ω3-, ω6-, ω9-desaturase, whose activity by temperature fall of atmospheric air was worst increase.
