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).
关于一系列性状与资源供应及植物潜在生长速率之间关系的生态学理论主要集中在叶片结构和生理方面——而对于根结构和生理的种间变异模式了解得要少得多。在本期中，瓦尔和赖泽通过证明一系列适应不同肥力水平生境的多年生温带禾本科植物的根结构与潜在生长速率及株高之间存在重要相关性，缩小了这一知识差距（见第459 - 471页）。
