Acorn yield and tree diameter relations in Turkey oak (Qercus cerris L.)

Abstract

Acorn production, diameter at base, diameter at breast height, and ratios were related in Turkey oak also known mossy oak (Qercus cerris L.) in this study. Data of 50 trees sampled from natural areas was collected to contribute silvicultural and other forestry practices of the species. Depending on results of correlation analysis, diameter at base, diameter at breast height had significantly effective on acorn production (r=0.56, 0.48, p<0.05), while ratios of diameters were not significantly effective on the production (p>0.05). Results of the study were discussed for potential forestry practices of the species.
