Foliar N and P resorption and nutrient levels along an elevational gradient in Juniperus oxycedrus L. subsp macrocarpa (Sibth. & Sm.) Ball
Özet
Juniperus oxycedrus L. subsp. macrocarpa (Sibth. & Sm.) Ball occurs in the Mediterranean region, on the southern part of Turkey and has been widely used in landscape planning and stabilization of coastal dunes. In this study foliar N and P resorption and foliar N, P and K concentrations (on a leaf mass basis) were investigated in J. oxycedrus subsp. macrocarpa. Foliar N, P, and K concentrations and absolute and proportional N and P resorption rates along the topographic position were not changed significantly. Significant correlations were found between absolute and proportional P resorption rates and soil moisture status. However, there were no significant correlation between absolute and proportional N resorption rates and soil moisture status. Foliar N and proportional N resorption were significantly correlated although absolute N resorption was not significantly correlated with foliar N. However, foliar P was significantly correlated both absolute and proportional P resorption.
