Root structure and function in an ecological context

Authors


Abstract

Ecological theories concerning the relationship of suites of traits with resource supply and plant potential growth rate have concentrated primarily on leaf structure and physiology – much less is known about interspecific patterns of variation in root structure and physiology. In this issue, Wahl & Ryser reduce this knowledge gap by demonstrating important correlations of root structure with potential growth rate and height among a range of perennial temperate grass species adapted to sites of a wide range of fertility (see pp. 459–471).
