New insights into leaf and fine-root trait relationships: implications of resource acquisition among 23 xerophytic woody species.

ABSTRACT: Functional traits of leaves and fine root vary broadly among different species, but little is known about how these interspecific variations are coordinated between the two organs. This study aims to determine the interspecific relationships between corresponding leaf and fine-root traits to better understand plant strategies of resource acquisition. SLA (Specific leaf area), SRL (specific root length), mass-based N (nitrogen) and P (phosphorus) concentrations of leaves and fine roots, root system, and plant sizes were measured in 23 woody species grown together in a common garden setting. SLA and SRL exhibited a strong negative relationship. There were no significant relationships between corresponding leaf and fine-root nutrient concentrations. The interspecific variations in plant heigh
