Özet

Tree height, basal diameter, stem form, number, angle and diameter of branches were assessed in eight-year-old provenance test established by 30 seed sources of Scots pine (Pinus sylvestris L.) at Aydogmus and Kemer experimental sites of Southern part of Turkey. Growth of the provenances was also compared to two native species (Taurus cedar-Cedrus libani A. Rich., and Black pine-Pinus nigra Arnold.) of the region. Variations within provenance and among provenances, and relations among the traits were estimated. There were large differences (p <= 0.05) within provenance and among provenances for the traits, while sites showed similar (0.05 <= p) performance for tree height and stem form. For instance, average of tree height was 181 cm and varied between 138.3 cm and 229.8 cm in provenances of Aydogmus site, it was 184 cm and ranged from 130 cm to 246.1 cm in that of Kemer site. Averages of tree height of a provenance were 144.4 cm in Aydogmus and 194.5 cm in Kemer. Individual tree height of the provenance varied between 69 cm and 267 cm, and ranged from 51 cm to 280 cm in sites. Averages of tree height were 143.2 cm in Black pine 145.6 cm in Taurus cedar which were natural species of the region. There were mostly positive and significant (p <= 0.05) correlations among the traits. Results of the study were discussed for new plantations and breeding of the species.
