    ANALYSES OF CANE TISSUE PROFILES IN VITIS SPP.
    (Aloki Applied Ecological Research And Forensic Inst Ltd, 2024) Gokbayrak, G.; Kuzucu, F. C.; Engin, H.
    The work was carried out with the aim of analysing the size of cane tissues of the grapevine cultivar 5BB (Vitis berlandieri x V. riparia) and (CS, Vitis vinifera L.) at the microscopic level. Cane tissues of both cultivars were assessed. Cuttings were taken at the same cane diameter of CS and 5BB during the winter period 40 days after leaf fall. The cuttings were fixed in a FAA solution for microscopy. In this study, the cultivars showed significant differences in the parameters of the vascular tissues. A strong relationship was detected between the profile parameters of different tissues (xylem vessel diameter, xylem, phloem, primary phloem fibre, xylem vessel density). The CS cultivar showed wider xylem vessel diameters than the 5BB cultivar. The relationship between xylem vessel size in CS and 5BB cultivars and tissue profiles are discussed. We suggest that the anatomical profiles of cane tissues can provide useful information for further investigations of grapevines.

    IMPROVED METHODS OF CANE SAMPLES STAINING DESTINED FOR MICROSCOPIC EXAMINATION AND IMAGING
    (Aloki Applied Ecological Research And Forensic Inst Ltd, 2024) Kuzucu, F. C.; Gokbayrak, Z.; Engin, H.
    In this study, staining methods were used to improve the effective visualization of grapevine cane sections under a microscope using 'ring light'. The stains applied to the sections included Aniline Blue, Safranin O, Toluidine Blue O, Bromophenol Blue, Basic Fuchsin, Methyl Green, Giemsa Stain, Carmine and Fast Green FCF. The natural color differences observed between the tissues were similar. Therefore, staining was proven to be the most useful tool to increase the contrast in grapevine cane tissues. Different stains reacted with different cell types and components and revealed their unique color properties. In addition to single use of stains, Carmine + Methyl Green, Fast Green FCF + Bromophenol Blue and Safranin O + Bromophenol Blue were utilized as double staining. Among these applications, staining with Aniline Blue, Bromophenol Blue, Fast Green FCF, Safranin O, and Toluidine Blue O showed effective results on cell and tissue levels. In addition, successful results were obtained from double stains. Double staining was recommended for examining grapevine cane sections under a microscope. 'Ring light' has been developed to improve the coloration and sharpness on the surface of the stained sections under the microscope and during photography. The ring light offers the opportunity to illuminate the entire sample by using white light, yellow light and both light intensities in different

    The Combined Effects of 1-Methylcyclopropene and Modified Atmosphere Packaging on Fruit Quality of 'Fuyu' Persimmon Fruit During Storage
    (Int Soc Horticultural Science, 2010) Kaynas, K.; Sakaldas, M.; Kuzucu, F. C.; Bicen, E.
    In this research, the effects of modified atmosphere packaging (MAP), 1-methylcyclopropene (1-MCP) treatments and furthermore the combination of MAP and 1-MCP on quality of 'Fuyu' persimmon fruits during storage period were studied. Modified atmosphere packaging was based on low density polyethylene (LDPE); 1-MCP (Smartfresh (TM)) treatments were 625 and 1250 ppb for 24 hours at 18-20 degrees C. Treated and untreated control fruits were stored at 0-1 degrees C and 85-90% RH for 40, 80 and 120 days respectively. The quality parameters evaluated were; weight loss, fruit firmness, total soluble solids, titratable acidity, skin color and flesh color. Furthermore the decay incidence was determined visually. Postharvest 1-MCP (Smartfresh (TM)) treatments and modified atmosphere packaging affected some quality properties of 'Fuyu' persimmon fruits. Thus, the combination of the treatments was found the most effective as keeping the quality.
