Mercan köşk ( Majorana hortensis Moench )'de gelişme dönemlerine göre verim ve kalite

Mercanköşk Akdeniz bölgesinde doğal olarak yetişen çok yıllık çalı formunda bir bitkidir. Baharat olarak kullanımı yanısıra, uçucu yağının antimikrobiyal ve antibakteriyal özellikleri bulunmaktadır. Çukurova bölgesine çok iyi uyum gösteren Mercanköşk'ün en yüksek ortalama yaş herba (1077.2 kg/da) ve kuru herba verimi (492.9 kg/da) ile uçucu yağ verimleri (7.77 l/da) çiçeklenme sonrasında elde edilmiştir. Uçucu yağın ana bileşenlerini $gamma$ -terpinen, p-cymol ve terpineol oluşturmuştur. Geraniol, p-cymol ve cineol oranları sadece farklı gelişme dönemlerinden etkilenirken, sabinen, myrcen, Borneol, terpineol, thymol ve carvacrol oranlarının hem gelişme dönemlerine hem de yıllara göre değiştiği saptanmıştır.

Determination of yield and quality in marjoram as influenced by development periods

Marjoram, naturally grown in Mediterranean region, is a perennial shrub. It is used as spices, and its essential oil has also antimicrobial and antibacterial properties. Marjoram is well-adapted to Çukurova conditions, so, the highest fresh (1077.2 kg/da) and dried herba yields (492.9 kg/da) and essential oil yield (7.77 l/da) were obtained at post-flowering stages. The determined main components of its oil were $gamma$ -terpinen, p-cymol and terpineol. The contents of geraniol, p-cymol and cineol were found to be influenced by only development stages while sabinen, myrcen, borneol, terpineol, thymol and carvacrol contents were influenced by both development stages and experiment years.
