Effects Of South And North Aspects On Growth In 4- Years Reproductions Of Pinus Brutia

This study was carried out to determine aspectual (south and north) effect on growth by height and root-collar diameter in 4-years reproductions of Brutian pine (Pinus brutia Ten.) to contribute natural regeneration and other forestry practices in the species.   South aspect (105.5 cm for height and 25.7 mm for root-collar diameter) showed higher growth performances for the characteristics than north aspect (69.7 cm and 13.8 mm). Root-collar diameter was more heterogeneous than height based on coefficient of variations for at both aspects.Results of analysis of variance showed significant differences (p< 0.01) between aspects for the characteristics. There were positive and significant (p< 0.05) correlations between height and root-collar diameter at aspects.
