Abstract

Juniperus phoenicea L. occurs in the Mediterranean region in the southern part of Turkey and has been widely used in landscape planning to stabilise coastal dunes. In this study, seasonal nitrogen (N), phosphorus (P), potassium (K) and calcium (Ca) concentrations and foliar resorption were investigated in J. phoenicea. The concentrations of N, P and K declined in senescent leaves, while that of Ca increased. N, P and K were subject to high remobilization, whereas Ca was accumulated in senescent leaves. N, P, K and Ca concentrations in young and fallen leaves were significantly different.
