Özet
Bu çalışma, Bornova ekolojik koşullarında 2007 ve 2008 yıllarında klon seleksiyonu yöntemi ile geliştirilen dokuz Hypericum perforatum L. (Sarı Kantaron) klonu ile ticari Topaz çeşidinin bazı tarımsal ve kalite özelliklerini belirlemek amacıyla yürütülmüştür. Araştırmanın her iki yılında da ikişer biçim yapılmış, bitki boyu, yeşil herba verimi, drog herba verimi, üst yeşil herba verimi, üst drog herba verimi ve hypericin oranı belirlenmiştir. Araştırmada toplam olarak, 2007 yılı en yüksek yeşil herba verimi 2558.3 kg da -1 ile 16 no’lu klondan, üst yeşil herba verimi 1360.7 kg da -1 ile 12 no’lu klondan, üst drog herba verimi ise 539.7 kg da -1 ile yine 16 no’lu klondan elde edilmiştir. Denemenin ikinci yılında ise en yüksek yeşil herba veriminde 1, 2, 7 ve 16 no’lu klonlardan (sırasıyla 804.3, 796.5, 730.0 ve 686.9 kg da -1 ), üst yeşil herba veriminde 7 ve 16 no’lu klonlardan (403.3 ve 396.8 kg da -1 ), üst drog herba veriminde ise 16 no’lu klondan 141.7 kg da -1 olarak belirlenmiştir. Klonların verimi ve hiperisin içeriği üzerine yıl ve biçimin etkileri önemli bulunmuştur (P<0.05). Araştırma sonuçları, her iki yılda özellikle İzmir- Ödemiş-Bozdağ kökenli 16 no’lu klonun verim değerleri bakımından en yüksek, ticari Topaz çeşidinin ise verim bakımından en düşük, ancak hiperisin içeriği bakımından ise %0.286 ve %0.269 ile en yüksek değere sahip olduğunu göstermiştir.
This study was aimed to determine some agricultural and quality characteristics of nine Hypericum perforatum L. clones developed with clone selection method and Topaz commercial variety under Bornova ecological conditions in 2007 and 2008. In trials, the plants were harvested twice each year. Plant height, fresh and drog herbage yield, fresh and drog herbage yield of top part of plant and hypericin content were determined. As a total, the highest fresh herbage yield, fresh and drog herbage yield of top part of plant were obtained from clone 16 with 2 558.3, clone 12 with 1 360.7 and clone 16 with 539.7 kg da -1 in 2007, respectively. In 2008, the highest fresh herbage yield with clones 1, 2, 7 and 16 as 804.3, 796.5, 730.0 and 686.9 kg da -1 , and from top part of plant, fresh herbage yield with clones 7 and 16 as 403.3 and 396.8 kg da -1 and drog herbage yield with clone 16 as 141.7 kg da -1 were obtained, respectively. Effects of year and harvest time on yield and hypericin contents were statistically significant (P<0.05). Results concluded that clone 16 originated from &#272;zmir-Ödemiş-Bozdağ had the highest yield and Topaz, a commercial variety, was lowest for yield but the highest for hypericin contents (0.286% and 0.269%) at both years.
