Determination of Stomatal Density and Distribution on Leaves of Turkish Hazelnut (Corylus avellana L.) Cultivars
This study was carried out to determine stomatal distribution and density in leaves of 18 Turkish hazelnut cultivars. Stomata were detected only on the lower leaf surface (hypostomatous). The number of stomata varied between 83.08 (Kalınkara) and 117.73 (Sivri) per mm2. The length and the width of s...

| description | This study was carried out to determine stomatal distribution and density in leaves of 18 Turkish hazelnut cultivars. Stomata were detected only on the lower leaf surface (hypostomatous). The number of stomata varied between 83.08 (Kalınkara) and 117.73 (Sivri) per mm2. The length and the width of stoma in the cultivars were within the ranges of 22.00-27.45 μm and 17.00-22.61 μm, respectively. The longest and the widest stoma were measured in Yassı Badem. Among the cultivars, Sivri had the highest stoma index (17.15%) while Kalınkara had the lowest (10.55%). The number of epidermal cells varied between 567 and 681 per mm2. There were negative correlations for number of stomata with the stoma length (-0.407) and with stoma width (-0.380). The results showed that hazelnut cultivars have a unique stoma features which might be important in varietal identification.Keywords: Hazelnut; Stoma; Stomatal density; Stoma index |
