Interaction of Cone Production and Growth Characters in Brutian Pine (Pinus brutia Ten.) Populations

Tahir Yangin and Nebi Bilir

The study was carried out to contribute for silvi cultural and genetic breeding practices of the species based on two and three year age cone productions and growth characteristics (tree height, diameter at breast height, tree age) collected from fifty trees selected randomly from each three natural populations in beginning of 2013. Averages of two and three years cones were 18.1 and 43.6, respectively while there were large differences among populations and within population based on analysis of variance (pï‚£0.05). The relations were changed for the populations and characteristics, while diameter at breast height had positive and significant (pï‚£0.05) effective on cone production in polled populations. Results of the study were discussed for forestry practice and genetic-breeding of the species.
