Sažetak
A study on the types and distribution of trichomes, pollen morphology, chemical composition of essential oil (analysed by GC-FID and GC-MS), and the content of macroelements (Na, K, Ca, Mg) and trace elements (B, Fe, Cu, Mn, Zn, Al, Pb, Cr, Cd, Ni, Hg, As) analysed by ICP-AES was conducted on Micromeria croatica (Pers.) Schott. Non-glandular trichomes, peltate trichomes (typical hairs of Lamiaceae), small capitate trichomes (composed of one basal epidermal cell and one head cell) and larger capitate trichomes (composed of one basal epidermal cell, two to three stalk cells and one head cell with subcuticular space) were observed on leaves, stems, the calyx and corolla. Pollen of M. croatica had six apertures (hexacolpate) which were set in the equatorial pollen belt (zonocolpate) and showed medium reticulate ornamentation (hetrobrochate type). The essential oil contained from 27 to 39 constituents, the most representative of which were caryophyllene oxide and E-caryophyllene. Among the investigated macroelements, the content of K was highest (8, 730–10, 080 mg/kg). The content of trace elements ranged from 0.12 mg/kg (Cr) to 78.00 mg/kg (Fe) while the content of Cd, Ni, Hg, and As were lower than the limit of quantification.A study on the types and distribution of trichomes, pollen morphology, chemical composition of essential oil (analysed by GC-FID and GC-MS), and the content of macroelements (Na, K, Ca, Mg) and trace elements (B, Fe, Cu, Mn, Zn, Al, Pb, Cr, Cd, Ni, Hg, As) analysed by ICP-AES was conducted on Micromeria croatica (Pers.)
