Abstract
The paper presents data on the dendrometric parameters, a needle anatomy and an essential oil characterization of a radiate pine (Pinus radiata D. Don) in the conditions of the Southern Coast of the Crimea. The research was carried out on the model trees (age 70-80 years) growing in the territory of the Montedor Park. For research collected pine needles radiant cuts were made on the freezing microtome (MZ-2, Ukraine), were stained with Sudan III and examined with a light microscope Mikmed-5 (LOMO, Russia) equipped with a digital camera MS-3 (LOMO, Russia). The essential oil from the needles was extracted by hydrodistillation on Ginsberg devices and examined on a gas chromatograph 6890N (Agilent Technology, USA). The studies showed that radiata pine trees achieve their genetically determined parameters, compared to those in the nature habitats in Monterey (California, USA). A needle anatomical investigation clearly demonstrated typical structure. In the essential oil composition, predominance of monoterpenes, in particular a-and (3-pinenes with a large content of the latter was demonstrated. The peculiarity of P. radiata essential oil under the conditions of the Southern Coast of the Crimea, compared to some other regions, was the presence of limonene, which determined the stronger coniferous smell.
