Marked differences in standing biomass, length density, anatomy and physiological activity between white and brown roots in Fraxinus mandshurica Rupr. plantation

摘要

Root browning is closely related to physiological function, but the dynamic and underlying mechanism are poorly understood. Our objective was to explore the interrelationship between root browning, in the context of root branch order, and standing biomass, root length density, and soil resources availability at the ecosystem level.
