Bu çalışmada Anadolu kestanesinde (Castanea sativa Mill.) tohum büyüklüğünün çimlenme yüzdesi ve fidan morfolojisi üzerine etkisi araştırılmıştır. Çalışma, Akçakoca ilçesi Kestane Bayırı mevkiindeki farklı tohum büyüklüğüne sahip kestane ağaçlarından toplanan tohumlarda gerçekleştirilmiştir. Ortalama tohum ağırlığı 5 gr’dan küçük tohumlu olan ağaçlar bir grupta, 5-8 gr arasında olan ağaçlar bir grupta, 8 gr’dan büyük olan ağaçlar da bir grupta toplanmıştır.
In this study, the effect of seed size of the Anatolian chestnut (Castanea sativa Mill.) on germination and seedling morphology were investigated. The study was carried out with seeds that were collected from the chestnut trees with different seed sizes, which located on Kestane Bayırı in Akcakoca, Düzce. Trees were divided into three groups according to seed weight. The trees that have average seed weight of 5 g formed a group, the other groups’ average seed weight were between 5-8 gr, the last groups’ were average seed weight were greater than 8 gr.The seeds were allowed to swell in distilled water for 48 hours before germination. Then they were germinated in containers at 8 °C. Germinated seeds were planted in the polyethylene tubes that were of 25x10 size. Morphological characters were measured at the end of the vegetation period.In conclusions, germination percentage and seedling growth of large seeds was found to be the highest. Germination percentage and seedling growth of the seeds obtained from small seed trees came to be the lowest. It was determined that germination percentage and growth of seedlings varied depending on the seed size.
