“…The amount of chlorophyll varies between species as well as within species according to subspecies, varieties, and forms (Canova et al 2008;Cetin 2017). It is known that one of the important factors determining the amount of chlorophyll is the leaf structure (Taner & Sade 2005;Atar et al 2020). In this study, chlorophyll contents were statistically very significant in hazelnut cultivars (p˂0.000).…”

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.

“…Valuable information has been obtained in a few studies on this subject, and it has been determined that the movement of heavy metals within the plant varies depending on the plant variety and heavy metal. In studies conducted on annual rings, while Zn and Pb elements were replaced in Cedrus deodora, the Cu element was not displaced [40][41][42], the Ni element was limited [43,44], and Co was displaced in Cedrus atlantica [38], the Bi element is replaced in Cupressus arizonica, while the Cd and Ni elements are not [39], and Cd, Fe, and Al were not replaced in Corylus colurna [24] were determined by several research [44][45][46][47][48].…”

Accumulation and transfer of P and K, macronutrient elements for plants, in Corylus colurna L. stem sections

One of the most essential factors in plant development is the nutrient content in the soil. Phosphorus (P) and potassium (K), essential macronutrients in plant nutrition, are vital in plant growth and development. Therefore, although many studies have been conducted on these elements in agricultural plants, the number of studies on forest trees could be much higher. In particular, there needs to be more information about the accumulation and transfer of these elements in different plant tissues. This study examined the change and transfer of P and K concentrations in the Corylus colurna tree's trunk parts. Within the scope of the study, the differences in P and K concentrations in the Corylus colurna trunk were examined based on organ, direction, and period. As a result, the most elevated concentrations of both elements were in the barks; the difference in direction was not evident in the wood, and both elements could be transferred within the wood.

“…The lowest average values in June had seedlings of the "Rudnik" provenance, while in October the lowest average values had the "Grabova reka" provenance seedlings. Atar et al, (2020) investigated in their research the SPAD values of Quercus hartwissiana Steven species, in May and October, and obtained the average maximal SPAD value of 32.7 for May, and 28.8 for October. Jagiełło-Leńczuk et al (2015) reported maximal values for Common oak in mid-July, numbering 49.9 SPAD units, while the average value of measurements taken in the period from May to November was 31.8.…”

Chlorophyll is the main participant in the process of photosynthesis, which content can tell about plant physiological health condition. In this research, the SPAD values of the one-year-old Sessile oak seedlings of 5 Serbian provenances were measured during June, August, and October of 2021. The measuring was performed by the SPAD device, and the data were presented through the SPAD index values. The research results confirmed that the environmental conditions where the plants grow have a dominant effect on the chlorophyll content, concerning the origin of the individuals. In further research, it is necessary to accurately determine on a greater plant sample the relationship between chlorophyll content and SPAD index values.
