Türkiye’deki doğal Türk fındığı (Corylus colurna L.) popülasyonlarının durumu
Bu çalışmada Türkiye’deki 18 doğal Türk fındığı popülasyonunun konum ve iklim verileri irdelenmiştir. İncelenen popülasyonlar küçüktür (ortalama alan = 206 ha) ve deniz seviyesinden 700 ila 1600 m arasında bulunmaktadır. Popülasyon konumlarında yıllık ortalama sıcaklık 8.83°C (aralık: 6.9 − 11 °C) ve yıllık ortalama yağış 654.28 mm (aralık: 477 − 952 mm) olarak belirlenmiştir. Türün Türkiye’deki kurak ve yarı-kurak alanların ağaçlandırılmasında kullanılması yönünde bir ilgi vardır ancak incelenen popülasyonların sadece üçü yarı-kurak sahalarda bulunmaktadır. Diğer popülasyonlar daha nemli bölgelerde bulunmaktadır. Bu popülasyonların genetik yapısı belirlenmeli ve kapsamlı bir gen koruma programı gündeme alınmalıdır. Ayrıntılı köken (orijin) ve/veya döl denemeleri ile yarı-kurak sahaların ağaçlandırılmasında kullanılabilecek tohum kaynakları ve aileler belirlenmelidir.

Status of natural Turkish hazel (Corylus colurna L.) populations in Turkey
Location and climate information of 18 natural Turkish hazel populations in Turkey is reported. Populations are small (mean area = 206 ha) and are found at 700 m to 1600 m above sea level. Mean annual temperature is 8.83 °C and (range: 6.9 − 11 °C) and mean annual precipitation is 654.28 mm (range: 477 − 952 mm) at population locations. The species is of interest in Turkey for plantation in arid and semi-arid regions but only three of the 18 population locations are classified as semi-arid. The rest of the populations are located in more humid environments. The genetic structure of these populations should be determined and a comprehensive gene conservation program should be put in place. A through genetic testing (provenance and/or progeny tests) should be conducted to determine suitable seed sources and families for plantation in semi-arid environments.
