Common sage (Salvia officinalis L.) is one of the most valuable commercial medicinal and aromatic plants (MAP). It has served different treatments historically in folk medicine and has always been popular to use. This research was conducted to observe the effect of mycorrhiza infection and fertilization to the biomass and quality characteristics on common sage. The optimum N, P, K dosses and their combinations (NP, NK, PK, NPK) were applied to both +M (mycorrhiza infected) and -M (non mycorrhiza infected) plants. The research was carried out both in the greenhouse and the plants were transferred to the field. The field trial was established in randomized block design with tree replication at ALC, UMass and three harvests were recorded at the growing season in 2014. Yield parameters showed significance between -M and +M applications. The essential oil contents were extracted by vapor distillation, and the major components of the essential oils were determined as camphor, α-thujon, ß-thujon, α-humulene, viridiflorol and eucalyptol (1.8 cineole) by GC-Ms. The highest camphor was received from P (-M) and PK (+M) fertilization with 31.64% and 33.54%. And the highest α-thujon was recorded at PK (-M) and NK (+M) combinations with 27.51% and 34.24%, respectively.

ÖzIslah çalışmaları ile domates ve ürünlerinin fonksiyonel özellikleri geliştirilebilmektedir. Domatesin fiziksel ve kimyasal özellikleri, çeşit özelliği başta olmak üzere birçok faktörden önemli oranda etkilenmektedir. Bu çalışma kapsamında melezleme sonucu geliştirilen üç domates çeşidi ile bu çeşitlerin elde edilmesinde kullanılan altı ana ve baba bireyin önemli kalite özelliklerinin karşılaştırılması yapılmıştır. Bununla birlikte çalışmada 10 adet ticari domates çeşit ve yerel genotiplerinin kalite özellikleri de araştırılmıştır. Çalışmada bu amaçla toplam 19 farklı materyal kullanılmıştır. Araştırmada elde edilen sonuçlara göre, ana ve baba bireyler, bunlardan elde edilen domates çeşitleri ve denemede kullanılan ticari çeşitlerin bazı fiziksel ve kimyasal özelliklerinde önemli farklılıklar olduğu görülmüştür. Örneklerin önemli kalite özelliklerinden suda çözünür kuru madde, glukoz ve fruktoz oranları, likopen içeriği ile kırmızılık göstergesi olan a* renk değeri sırasıyla %3.65-7.20, %0.61-1.81, %0.88-2.37, 37.45-85.82 mg kg -1 , 14.52-32.28 arasında değişim göstermiştir. Araştırma sonucunda melezleme çalışmaları ile domatesin şeker bileşimi, likopen içeriği ve renk gibi kalite özelliklerinde varyasyon oluşturulabileceği görülmüştür. Islah çalışmaları mevcut ürün çeşitliliğinin arttırılması noktasında da oldukça önemlidir. AbstractFunctional properties of tomatoes and their products could be improved with breeding studies. The physical and chemical properties of the tomato could vary according to cultivars and also many growing factors. In this study, some quality parameters of three tomato hybrid cultivars were compared with their parents and also some commercial tomato varieties and local genotypes. Totally, 19 different genotypes were used for this purpose. According to obtained results, there were significant differences in some physical and chemical properties of them. The significant quality traits, such as water soluble dry matter, glucose and fructose ratios, lycopene content and the a* colour values varied between 3.65-7.20%, 0.61-1.81%, 0.88-2.37%, 37.45-85.82 mg kg -1 , 14.52-32.28, respectively. As a result, new varieties, which have different characteristics, could be improved by crossing studies. The product variety enriched with breeding trials is important on market demands. As a result, variations in quality characteristics, such as sugar composition, lycopene content and colour values of tomato can be generated hybridization studies. Breeding studies are also important in increasing the current product range for tomato.
