The content and dynamics of accumulation of essential oils of <i>Myrtus communis</i> L., <i>Rosmarinus officinalis</i> L., <i>Laurus nobilis</i> L. under the conditions of the introduction in Azerbaijan

The article presents the results of a comparative study mass fraction essential oil and dynamics its accumulation in leaves subtropical introduced species Laurus nobilis L., Myrtus communis L. Rosmarinus officinalis Mardakian Arboretum located on Absheron Peninsula. These are cultivated as evergreen trees shrubs, with an optimal autumn-winter leaf ripening period. natural conditions this region Azerbaijan characterized by dry climate. studies have shown that raw materials dried to air-dry state contain 1.5 times more compared other species, both average for entire period separately each month, greatest November (mass 0.88%). features related biological properties these crops their growth shown. If shrubs clearly expressed seasonality biosynthesis associated period, then , tree crop, has no pronounced from September March. In culture Peninsula, it is late accumulation, respectively, high rosemary October-November (from 0.83 0.88%) beginning second wave flowering; maximum yield myrtle (8.3 g/kg) was recorded February - during full leaf. conducted confirm assessments earlier prospects introduction into climate indicate content. data obtained allow us recommend autumn year harvesting time best winter order obtain oil.
