Tree rings of cedrus libani at the northern boundary of its natural distribution
2003
Akkemik, Ünal
The present study was carried out taking a total of 41 increment cores from three sites located in the northern boundary of Cedrus libani and three site chronologies were constructed. Three response functions were computed and a higher correlation with climate was found in the trees on the steep slopes. The low precipitation was an important limiting factor for growth. At the valley bottom site, neither precipitation, except for December, nor temperature, except for February were a limiting factor. The radial diameters of tracheids were measured, and the tracheid numbers representing the last seven years, from 1994 to 2000, were counted. Although the radial diameters were almost similar in all sites, the numbers of tracheids were greatest at the valley bottom site and lowest at the steep slope site.
