A different level of essential oil content in the studied climatypes of Scots pine was established according to the groups of monoterpenes, sesquiterpenes and an oxygen-containing component. Also significant differences in the content of a number of components within each of the studied groups were revealed. The authors obtained data on the composition of the essential oil and the ratio of a number of components in it within various groups among climatypes, subspecies and varieties of Scots pine (subspecies Lapland, Siberian, forest-steppe, European, European Western and Eastern varieties). These results will allow further selection of the most promising climatic ecotypes for breeding for resistance to biotic and abiotic environmental factors, taking into account the indicators of productivity of forest stands, the quality of trunks, vital state of trees in the plantation, their safety, growth and development. The obtained information on the content of essential oil components in the needles of climatypes and subspecies of Scots pine makes it possible to broaden our knowledge on ecological sustainability of plants, especially under the conditions of the visible climate change.
