【 摘 要 】

The thyme (Thymus sipyleus BOISS. subsp. sipyleus BOISS. var. sipyleus L.) plant was rooted from its natural environment at an altitude of 1750 m from Beyşehir Muslu Yayla location and was cultured at 1345 m altitude in Beyşehir İslibucak. Nitrogen + Phosphorus + Potassium (K1), Micro Elements (Boron + Copper + Iron + Manganese + Molybdenum + Zinc) (K3) and Nitrogen + Phosphorus + Potassium + Micro Elements (Boron + Copper + Iron + Manganese + Molybdenum + Zinc) (K2 and K4) was used as fertilizer mixtures for thyme production. Plant samples were harvested in three separate periods in August, September and October 2019 and SPME-GC-MS was used for the analysis of its volatile components. The results showed that the applied fertilizer mixtures and the harvest period provided a variety in the amounts of the thyme plant main volatile components. The highest value of p-cymene (43.76%) in the October harvest of thyme produced using K4 fertilizer mixture application, the highest value of γ-terpinene (24.79%) in the August harvest of thyme produced using K4 fertilizer mixture application, the highest value of thymol (20.26%) in the August harvest of thyme produced using K3 fertilizer mixture application and the highest value of carvacrol (67.01%) in the September harvest of thyme produced using K1 fertilizer mixture application were observed.
