Abstract
The composition of fatty acids of total lipids of the outer and parenchymal part of the pericarp in Cydonia oblonga Mill and Mespilus germanica L. Maloideae (ROSACEAE), growing in the Northern Caucasian mountains at altitudes of 300, 500, 700, and 1200 m above sea level in various natural zones from experimental sites, was studied for the first time. It is established that the altitude of plant growth is largely correlated with the changes in the FA composition of the outer, but not the parenchymal, part of the pericarp. The nature of this variability suggests that the adaptation of plants to the conditions of significant temperature differences in the mountains is associated with the regulation of cell membrane fluidity, based on the interaction of opposite processes of synthesis of polyunsaturated and very-long-chain fatty acids.
