A total of 120 female Japanese quails were randomly allocated to 6 treatment groups with 5 replicates each. Treatment groups were formed by supplementing 0, 1, 2, 3, 4 and 5 g/kg orange peel powder to the basal diet. Performance parameters such as body weight, body weight change, egg production, egg weight, egg mass, feed intake, and feed conversion ratio and egg quality parameters of laying quails were not affected by the addition of orange peel to the diet. Egg yolk DPPH (2,2 diphenyl-1-picrylhydrazyl) activity increased linearly with the addition of orange peel powder to the diet compared to the control group, but this effect was not observed at egg yolk TBARs (thiobarbituric acid reactive substances) level. At the end of the study, it was determined that orange peel powder could be used in the di...

Domates meyvelerinin fiziksel ozelliklerinden geometrik, hacimsel ve renk ozellikleri (boyutlar, kuresellik, geometrik ortalama cap, yuzey alani, yigin hacim agirligi, meyve hacim agirligi, porozite, L*, a*, b* renk karakteristikleri), mekanik ozellikleri [(domatesin X uzunluk ve Y genislik eksenleri icin kabuk yirtilma kuvveti, deformasyon, deformasyon enerjisi, statik surtunme katsayisi ile domatesin sap kopma direnci)] ile kimyasal ozelliklerinden suda cozunebilir kuru madde, pH ve titre edilebilir asitlik belirlenmistir. Muhafaza suresi arttikca boyut ve agirlikta azalmalar gorulmustur. Olgunlasma donemi ve muhafaza suresinin kuresellik ve geometrik ortalama cap uzerindeki etkileri istatistiksel olarak onemsiz cikmistir. Meyvelerin kabuk ve kabuk alti a* degerleri olgunlasma artti...

Fungicides are commonly used for the control of this pathogen. Currently, resistance to fungicides, which provide the effective and fast control of pathogens, is an important problem. In this study, resistance of B. cinerea isolates obtained from tomato greenhouses in Antalya province against Signum® (boscalid + pyraclostrobin) and Cantus® (boscalid) fungicides were evaluated under in vitro conditions. Mycelium growth tests conducted with different fungicide concentrations and EC50 values were calculated. While EC50 values of isolates sensitive to boscalid varied between 0.7 and 8.6 μg/ml, EC50 values of isolates sensitive to boscalid + pyraclostrobin were found to be between 0.1 and 1.9 μg/ml. Conidial germination tests were carried out in a 2% water agar (WA) medium. It was determined that isolates 61, 69, 72, and 81 were resistant to b...
