Abstract:

 This study examined the leaf micromorphological properties, stomatal indexes, and chlorophyll contents of 20 Turkish hazelnuts Corylus avellana cultivars. The cultivars examined included the Acı, Allahverdi, Cavcava, Çakıldak, Foşa, Giresun melezi, Incekara, Kalınkara, Kan, Karafındık, Kargalak, Kuş, Mincane, Okay 28, Palaz, Sivri, Uzunmusa, Tombul, Yassı Badem, and Yuvarlak Badem. The chlorophyll content was measured by a portable chlorophyll meter and the surface sections of leaves were excised by hand and all measurements were obtained by using imaging software NIS - Elements, Version 3.00 SP5. The stomatal index per unit area 1x 104 μm2 was calculated. For scanning electron microscope SEM imaging, the dried leaves were mounted on stubs using double-sided adhesive tape. The leaf samples were coated with 12.5-15.0 nm of gold and the coated leaves were photographed using a Hitachi SU 1510 Scanning Electron Microscope. Three wax ornamentation types were found in the leaf samples e.g., crust, smooth, and granules. The epidermal features, stomatal index, and chlorophyll quantities showed some differences among the C. avellana cultivars. The importance of stoma width and stoma length were determined for the Palaz, Kuş, Yuvarlak Badem, and Yassı Badem. The stomatal index and width and length of upper epidermis and lower epidermis were identified as distinctive properties for the Allahverdi, Kargalak, Kara, and Mincane. The chlorophyll density was identified as a distinctive feature of the Sivri, Çakıldak, Incekara, and Acı cultivars. The highest correlation was found at a rate of 0.98 between Okay 28 and Tombul while the lowest correlation was found at a rate of 0.87 between Sivri-Karafındık, Sivri-Foşa, and Sivri-Kargalak.
