Abstract

Germination tests were applied at 3 °C, 10 °C (after 12 weeks prechilling), 15 °C, and 20 °C after 8, 10 and 12 weeks prechilling treatments to examine Oriental beechnuts germination behaviour at different temperatures. 12 weeks prechilling duration required for the full dormancy removal of beechnuts. Oriental beechnuts were demonstrated the highest germination percentage in the shortest time at 15 °C after 12 weeks prechilling duration. Germination rate were significantly decreased at 20 °C because of secondary dormancy. Considering the germination rate, the mean germination time, and the germination value, 15 °C appeared to be the most approppriate germination temperature for the prechilled Oriental beechnuts.

Özet

Doğu kayını tohumlarının farklı sıcaklıklardaki çimlenme tutumlarını belirlemek amacıyla 8, 10 ve 12 haftalık katlama işlemlerinden sonra 3 °C, 10 °C (sadece 12 haftalık katlama sonrasında), 15 °C ve 20 °C’de çimlenme testleri gerçekleştirilmiştir. Bütün tohumlardaki uyku halinin giderilmesi için 12 haftalık katlama işlemi gerekmiştir. 12 haftalık katlama işleminden sonra Doğu kayını tohumları, en kısa sürede en yüksek çimlenme oranını 15 °C’de sergilemiştir. 20 °C’de ikincil uyku hali (sekonder dormansi) nedeniyle çimlenme oranı önemli oranda gerilemiştir. Çimlenme yüzdesi, ortalama çimlenme süresi ve özellikle çimlenme değeri verileri dikkate alındığında, katlama işlemi görmüş Doğu kayını tohumları için en uygun çimlenme sıcaklığı olarak 15 °C bulunmuştur.
