“…Stomatal distribution or also called stomata index is calculated from the ratio of the number of stomata to epidermal cells in a certain unit. The measurement method of stomatal distribution refers to Meidner & Mainsfield in Avci & Aygün [4] with the formula as follows: The number of stomatal and epidermal cells were counted from slide prepared using replica method. The number of stomata was counted under a microscope with 10x10 magnifications using a hand counter.…”

“…Avci & Aygün [4] stated that the spread of stomata in the epidermis was influenced by variations in species and varieties in types and growing conditions. In addition, Juairiah [20] stated that differences in the distribution of stomata in each plant could be caused by genetic and phenotypic factors and are influenced by environmental factors.…”

Changes in leaf anatomy can be influenced by the surrounding environment and several other factors. Shade plants or ornamental plants themselves also have their characteristics in responding to surrounding conditions through transpiration. This study aimed to measure the rate of transpiration related to changes in the distribution of stomata and leaf thickness of six types of dicot ornamental plants and to describe the leaf anatomy of each type. The experiment used Completely Randomized Design (CRD) with six types of plants as treatment with three replications. Transpiration rate was measured by modified lysimeter method, stomatal distribution was calculated from the ratio of the number of stomata to epidermal cells and leaf anatomy was observed using preserved slide made from paraffin method. Data were analyzed by SAS with CRD model and correlation was performed between transpiration rate and leaf thickness. The results showed that the transpiration rate, leaf thickness, and stomatal distribution were significantly different at α = 0.05 amongst plants. The transpiration rate was inversely proportional to leaf thickness with various correlation coefficients. The leaf anatomy of six plant species showed various thicknesses between tissues. Further research needs to be done to explain the rate of transpiration with changes in leaf anatomy.

Objective: In this research, evaluations of F1 fall pear hybrids, that obtained from different cross combinations, were made to contribute to our country' s agriculture and gene pool.Material and Methods: 11 hybrids investigated in this research were obtained from the cross combinations that 'Magness' , 'Kiefer' , 'Williams' and 'Santa Maria' cultivars were maternal and, 'Güz' , 'Santa Maria' and 'Kiefer' cultivars were used as pollinator parents. Susceptibilities of those hybrids to fire blight disease, pomological and biochemical characteristics were determinated. Besides, sensory parameters were added to the data attained by the measurements, and promising hybrids were detected through the modified weighted ranking method.Results: Fruit width, fruit length, shape index, fruit weight, fruit firmness, soluble solid content, pH, titratable acidity, vitamin C and antioxidant activity characteristics were varied between 53.22 -84.25 mm, 52.91 -105.01 mm, 0.95 -1.62, 86.51 -317.70 g, 3.32 -8.41 kg/cm2, %8.77 -16.53, 3.52 -4.73, %0.14 -0.59, 0.53 -3.17 mg.L-1 and %26.43 -%75.09, respectively. Eight hybrids were evaluated as promising fall cultivars through the modified weighted ranking method.Conclusions: Due to the lack of a definite solution against fire blight, the chemicals used are harmful to human health and organic cultivation is becoming more widespread, the pears with high fruit quality parameters and disease resistant hybrids will come to the fore in the near future, it is thought that the hybrids (2-12-43, 2-15-93, 2-12-47, 1-17-20, 3-36-87, 2-33-32, 2-15-33 and 1-16-130) transferred to the forward observation plot will contribute to pear cultivation by registering in the following period. ÖZAmaç: Bu çalışmada, farklı melezleme kombinasyonları sonucu elde edilen güzlük F1 armut melezlerinin, ülke tarımına ve genetik havuza katkı sağlaması amaçları doğrultusunda, değerlendirmeleri yapılmıştır.

“…In addition, the number of stomata and stomatal properties affect gas exchange, photosynthesis production, drought resistance, and vegetative development (Çağlar & Tekin 1999;Çağlar et al 2004;Drake et al 2013). The number of stomata per unit area, stomata, and epidermis properties varies according to species and cultivars (Çağlar et al 2004;Akçin et al 2013;Avcı & Aygün 2014;Hurt & Doğan 2020). Although leaf micromorphological features such as cuticular wax types, and epidermal and stomatal properties have been used in the identification of plants, the literature survey has shown that no comprehensive study has yet been conducted.…”

“…There are some data on leaf epidermis micromorphologies of the Corylus species. Uzunova (1999) investigated the leaf epidermis in European Corylaceae while Avcı & Aygün (2014) determined the stomata density and distribution in the leaves of 18 varieties of Turkish hazelnuts. There is, however, no data on the micromorphological properties of Turkish hazelnut cultivars.…”

In the present study, leaf micromorphlogical properties, stoma indexs and chlorophll contents of 20 Turkish hazelnut (Corylus avellana) cultivars were studied. Investigated cultivars were “Acı, Allahverdi, Cavcava, Çakıldak, Foşa, Giresun melezi, Incekara, Kalınkara, Kan, Karafındık, Kargalak, Kuş, Mincane, Okay 28, Palaz, Sivri, Uzunmusa, Tombul, Yassı Badem, Yuvarlak Badem”. Three wax ornamentation types are recognized; crust, smooth and granules. Epidermal features, stomatal index and chlorophyll amounts showed some differences between C. avellana cultivars. Stoma width and stoma length were determined to be important for Palaz, Kuş, Yuvarlak Badem ve Yassı Badem cultivars. Stoma index, upper epidermis and lower epidermis width, upper epidermis and lower epidermis length values were determined to be distinctive for Allahverdi, Kargalak, Kara and Mincane. Chlorophyll density was found to be distinctive for Sivri, Çakıldak, İncekara and Acı cultivars The highest similarity was found between Okay 28 and Tombul cultivars with a rate of 0.98. The lowest similarity was found between Sivri-Karafındık, Sivri-Foşa and Sivri-Kargalak with 0.87.

Determination of Stomatal Density and Distribution on Leaves of Turkish Hazelnut (Corylus avellana L.) Cultivars

Abstract: 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 mm
