This study has been conducted between 2015 and2016 at Hazelnut Research Institute in Giresun. Theobjective of this study was to determine the effects ofthe pollinizer cultivars on the nut and kernelcharacteristics. Tombul, Palaz, Çakıldak, Foşa andAllahverdi were used as main cultivars whileTombul, Palaz, Çakıldak, Foşa, Allahverdi, Sivri,Kalınkara and Yassı Badem were used as pollinizercultivars. Self-pollination was considered as acontrol and open-pollination was taken as anapplication. In the study, it was determined that thepollinizer cultivars caused changes in some nut andkernel characteristics with the xenia and metaxeniaeffects. The effects of pollinizers on nut set andnumber of nut in clusters were quite obvious. Selfpollination resulted in low nut set and number of nutin clusters, indicating it is self-incompatible. Openpollination and different cross-pollinationtreatments increased nut set and number of nut inclusters. It is estimated that the changes in thepomological characteristics may be related to the nutset as well as the pollen sources. The kernelpercentage and good kernel were generally low inself-pollination. Open-pollination and crosspollination treatments increased kernel percentageand good kernel. It has also been improved that thepollinizer cultivars may cause changes in nut shape.Palaz pollination treatment caused decrease of nutshape index in main cultivars.
