Abstract:
In this study, the relationships between height-diameter at breast height (DBH),
crown diameter-DBH and crown diameter-height were investigated in Calabrian
pines (Pinus brutia Ten.) of Baskonus Mountain, Kahramanmaras. Four sample
plots were selected from pure Calabrian pine stands and DBH, height and crown
diameter were measured on the live Calabrian pine trees, of which DBH was >
4 cm, in these sample plots. At the end of the regression analysis carried out
on the data of a total of 134 trees, it was determined that there were statistically
significant (P<0.0001) and strong (R2>0.50) relationships between
DBH, height and crown diameter variables in Calabrian pines. The strongest relationship
determined was the height-DBH relationship (R2=0.82), followed by
the crown diameter-DBH (R2=0.74) and crown diameter-height (R2=0.62)
relationships, respectively. The results of the study indicated that the height-DBH
relationship can be described by the second-degree polynomial model, while the
crown diameter-DBH and crown diameter-height relationships can be described
by the power model and heights and crown diameters can be estimated by means
of DBH, of which measurement is easy, in Calabrian pines of the research area.
