Spatio-Temporal Variations in Allocation of Macronutrients in Smilax Excelsa L. (Liliaceae)

Abstract

Allocation patterns of macronutrients (N, P and K) of a liana species Smilax excelsa were investigated in different habitats and along growing season. Macronutrient concentrations significantly differed according to the season (except for leaf K concentration). Similarly, significant differences were also found among sampling stations except for stem and rhizome N and rhizome K% concentrations. Soil macronutrient concentrations were significantly different among studied stations, but not among seasons. S. excelsa individuals occurring in open canopies and overstory positions allocated more macronutrients to fruits as compared to those occurring in closed canopies and understory positions.
