Özet

Oregano holds an important place among medicinal and aromatic plants and has been used for centuries. This study was conducted to determine the effect of diurnal variability on five different genotypes (Oguz variety, Origanum majorana, Denizli 1, Denizli 2, and Antalya) belonging to the Origanum genus. The study was conducted in 2021 in Kahramanmaraş under field conditions that had completed their establishment year. Five different harvest times (06:00, 09:00, 12:00, 15:00, and 18:00) were established to determine diurnal variability in oregano. The harvest was carried out during the full flowering period of the oregano plants. Looking at the data obtained from the experiment, the essential oil content of the genotypes ranged from 1.53% to 3.90%, with the highest essential oil content obtained from the Antalya genotype. No statistical difference was observed in the essential oil content at the harvest times. Looking at the essential oil components, the number of components varies according to genotypes. Looking at the essential oil components in oregano, carvacrol was the main component and had values ranging from 54.72% to 85.72% in the genotypes examined, while thymol had values ranging from 0.84% to 42.20%. The essential oil component ratios and number of components varied according to harvest times. It was found that the second and fourth harvest periods were suitable in terms of essential oil content and components.

Abstract

Oregano holds an important place among medicinal and aromatic plants and has been used for centuries. This study was conducted to determine the effect of diurnal variability on five different genotypes (Oguz variety, Origanum majorana, Denizli 1, Denizli 2, and Antalya) belonging to the Origanum genus. The study was conducted in 2021 in Kahramanmaraş under field conditions that had completed their establishment year. Five different harvest times (06:00, 09:00, 12:00, 15:00, and 18:00) were established to determine diurnal variability in oregano. The harvest was carried out during the full flowering period of the oregano plants. Looking at the data obtained from the experiment, the essential oil content of the genotypes ranged from 1.53% to 3.90%, with the highest essential oil content obtained from the Antalya genotype. No statistical difference was observed in the essential oil content at the harvest times. Looking at the essential oil components, the number of components varies according to genotypes. Looking at the essential oil components in oregano, carvacrol was the main component and had values ranging from 54.72% to 85.72% in the genotypes examined, while thymol had values ranging from 0.84% to 42.20%. The essential oil component ratios and number of components varied according to harvest times. It was found that the second and fourth harvest periods were suitable in terms of essential oil content and components.
