Abstract: (124 Views)

The aim of this study was to evaluate the changes in the essential oil chemical composition of Satureja bachtiarica Bunge were inoculated by spores of the arbuscular mycorrhizal inoculation Glomus caledonium and foliar application of zinc chelate levels (0, 2, 4 and 8 g/L) in 2019, at Zarrin Giah greenhouse of Urmia city in West Azerbaijan Province, in a randomized complete block design with three replications. Plants were harvested at full flowering stage. Essential oils were obtained by Clevenger apparatus and were analyzed by GC and GC/MS. Comparison of means by Duncan's multiple range test showed that inoculation with Glomus caldonium had no significant effect on the essential oil yield of Satureja bachtiarica flowering shoots, but the foliar application of zinc chelate had statistically significant effect. However, there was no difference among different concentrations of zinc chelate in terms of effect on essential oil yield. The treatments also changed the essential oil composition compared to the essential oil of the control group. These changes included the reduction of beta-caryophyllene, sabinen hydrate, borneol and carvacryl acetate compounds and the increase of citral and octyl phthalate in the plant inoculated with mycorrhiza, as well as the increase of carvacrol in the essential oil of plants treated with zinc chelate. Also, inoculation with mycorrhizal fungi and zinc chelate foliar application increased the amount of sesquiterpene & diterpene and monoterpene compounds, respectively.
