The composition of fatty acids of total lipids of the outer and parenchymal parts 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.
首次对生长在北高加索山脉海拔300米、500米、700米和1200米的不同自然区域实验点的榅桲（Cydonia oblonga Mill.）和欧洲花楸（Mespilus germanica L.，蔷薇科苹果亚科）果皮外层和实质部分总脂质的脂肪酸组成进行了研究。结果表明，植物生长的海拔高度与果皮外层而非实质部分脂肪酸组成的变化在很大程度上相关。这种变异性的本质表明，植物对山区显著温度差异条件的适应与基于多不饱和脂肪酸和极长链脂肪酸合成相反过程相互作用的细胞膜流动性调节有关。
