Spike lavender (Lavandula latifolia) is an aromatic shrub cultivated worldwide for the production of essential oils. The major constituents of these oils are monoterpenes, which are obtained from isopentenyl diphosphate and dimethylallyl diphosphate precursors through the plastidial methylerythritol phosphate (MEP) pathway and/or the cytosolic mevalonate pathway. 1-Deoxy-D-xylulose-5-P synthase...

the focus of the present study was to investigate the chemical composition of essential oil of salvia hydrangea dc. ex benth. growing wild in kiasar-hezarjrib, iran. in addition, effects of altitude and some soil properties on the essential oil quality and quantity of s. hydrangea was identified. the samples collected from two altitudes (1100 and 2000 m) in blossoming period, were analyzed by h...

in this research, the effects of organic fertilizers (bovine, sheep, leaf mould and vermicompost fertilizers) combined with foliar application of salicylic acid (sa) at the rate of 0, 10-2, 10-4 and 10-6 m on essential oil percentage and some secondary metabolites of lemon balm were investigated. the experiment was conducted as complete randomized block design with factorial arrangement in pots...

This research was aimed at investigating the essential oil production, chemical composition and biological activity of a crop of pink flowered oregano (Origanum vulgare L. subsp. vulgare L.) under different spatial distribution of the plants (single and binate rows). This plant factor was shown to affect its growth, soil covering, fresh biomass, essential oil amount and composition. In particul...
