Comparison of two methods to assess the root architecture as the potential factor influencing the diversity of a stand

Abstract

In this article we describe two methods for acquisition and examination of the root architecture of trees in order to evaluate the possible influence on stand diversity and horizontal structure. The roots and belowground biomass in semi-arid areas of south Portugal can be understood as the main competition area for the trees so understanding of their growth and architecture is essential for understanding of growth, interaction among plants and finally the diversity of the stand
