Abstract

This study was carried out in Kastamonu Taşköprü-Tekçam Sarıçam (Pinus sylvestris L.) clonal seed orchard. In the study, the correlations between the number of cones and tree diameter at breat height (d1,30), leaf area index (LAI) and the clones were inquired, and the heritability ratios (H2) depending on these characters were calculated. As a result of the study, as changes in the number of cones depending on the clones, LAI and tree diameter were examined, it was found that there were significant correlations between the number of cones and LAI as well as clones (p<0.05). No significant correlation was found between the LAI (0.72 - 2.18 m2m-2) and diameter at breat height (14.8 - 30.9cm.) (p>0.05). It has been determined that the cone yield of a tree differs according to the clones (p<0.05). In the study, the heritability values were calculated; the highest heritability value was obtained in the number of H2 cones and the values obtained in LAI were far below the average. The significant correlation between the cone yield and the LAI, which seems to be very important for the clonal seed orchards, shows that the LAI is also a critical factor for the optimization of the seed yield.

Özet

Bu çalışma Kastamonu Taşköprü-Tekçam Sarıçam (Pinus sylvestris L.) klonal tohum bahçesinde gerçekleştirilmiştir. Çalışmada; klonlar üzerinde göğüs yüzeyi çapı (d1,30), Yaprak Alanı İndeksi (YAİ) ve kozalak sayısı arasındaki ilişki ortaya konulmaya çalışılmış ve bu karakterlere bağlı kalıtsallık oranları (H2) hesaplanmıştır. Çalışma sonucunda, klonlardaki kozalak sayısının YAİ, ağaç çapı ve klonlara göre değişimi incelendiğinde kozalak sayısı ile YAİ ve klonlar arasında bir ilişki olduğu ortaya konulmuştur (p<0.05). YAİ değerleri 0.72-2.18m2m-2 (ort. 1.4m2m-2) ile göğüs çapı 14.8 - 30.9cm (ort. 23cm) arasında ise anlamlı bir ilişki bulunmamıştır (p>0.05). Bir ağacın kozalak veriminin klonlara göre de farklılık gösterdiği tespit edilmiştir (p<0.05). Çalışmada ölçülen karakterlere bağlı kalıtsallık değerleri hesaplanmış ve en yüksek kalıtsallık değeri H2 kozalak sayısında elde edilmiş olup, YAİ bakımından elde edilen değerler ise ortalamanın çok altında kalmıştır. Klonal tohum bahçeleri için oldukça önemli olan kozalak verimi ile YAİ arasındaki anlamlı ilişkinin ortaya konulmuş olması tohum verimini optimize eden uygulamalarda YAİ’nin de değerelendirilebilir bir karakter olduğunu göstermektedir.
