Relationships between specific root length and respiration rate of fine roots across stands and seasons in Chamaecyparis obtusa

Aims Fine root respiration (R r ) is closely linked with fine root morphology, especially with specific root length (SRL), in short-term measurements in some tree species. However, whether these relationships are also valid across different stands and seasons is not yet known. This study aimed to investigate these relationships in the fine roots of Chamaecyparis obtusa.
