Bu araştırma, farklı hasat zamanlarının (Z1: 16 Ağustos, Z2: 29 Ağustos, Z3: 14 Eylül, Z4: 28 Eylül, Z5: 15 Ekim ve Z6: 31 Ekim) biberiye (Rosmarinus officinalis L.) bitkisinin verim ve kalite özellikleri üzerine etkisini belirlemek amacıyla Eskişehir ekolojik koşullarında 2018 yılında yürütülmüştür. Deneme, tesadüf blokları deneme desenine göre 4 tekerrürlü olarak kurulmuştur. Biberiye bitkisinin drog yapraklarından su distilasyonu yöntemiyle elde edilen uçucu yağın kompozisyonu GC-MS ile analiz edilmiştir. Yürütülen çalışmada, ortalama bitki boyu (cm), yeşil herba verimi (t ha-1), kuru herba verimi (t ha-1), kuru yaprak verimi (t ha-1), uçucu yağ oranı (%) ve uçucu yağ verimi değerleri sırasıyla 61.87 cm, 15,78 t ha-1, 5.80 t ha-1, 3.55 t ha-1, % 0,69 ve 23.92 l ha-1 olarak tespit edilmiştir. Farklı zamanlarda yapılan hasatlardan elde edilen uçucu yağ örneklerinde 35 farklı komponent olduğu tespit edilmiştir. Analiz edilen uçucu yağ örneklerinde ana bileşen olarak tespit edilen camphor, 1-verbenone, α-pinene, borneol ve 1,8-cineol bileşenlerin değerleri sırasıyla %11.67-14.78, %8.47-11.77, %8.74-11.82, %8.61-11.12 ve 7.01-9.07 arasında değişmiştir.
The purpose of this research carried out in 2018 under Eskişehir ecological conditions was to determine the effect of six different harvest dates (T1: 16 August, T2: 29 August, T3: 14 September, T4: 28 September, T5: 15 October and T6: 31 October) on the yield and quality properties rosemary (Rosmarinus officinalis L.). The experiment was established according to a randomized complete-block design with four replications. The composition of the essential oil obtained by the hydro-distillation from the dry leaves of the rosemary plant was analyzed by GC-MS. In the experiment carried out, the mean values of plant height (cm), fresh herb yield (t ha-1), dry herb yield (t ha-1), dry leaf yield (t ha-1), essential oil ratio (%), essential oil yield were determined as 61.87 cm, 15.78 t ha-1, 5.80 t ha-1, 3.55 t ha-1, 0.69% and 23.92 l ha-1, respectively. In the essential oil samples obtained from the harvests made at different dates, 35 different components were identified. The values of the camphor, 1-verbenone, α-pinene, borneol and 1,8-cineol components determined as the main component in the analyzed essential oil samples ranged from 11.67 to 14.78%, from 8.47 to 11.77%, from 8.74 to 11.82%, from 8.61 to 11.12% and from 7.01 to 9.07%, respectively.
