Schematic representation of the linkage of organ carbon and soil organic carbon fractions under rainfall manipulation treatment (TE vs. CK) on moso bamboo plantations. Blue and black in the square represent positive and negative correlations between organ carbon and SOC fractions variables, respectively. The solid line represents significance, dashed line represents insignificance. The black upward arrow indicates an increase, the black downward arrow indicates a decrease. POC, soil particulate organic carbon; ROC, readily oxidizable carbon; MBC, microbial biomass carbon; MOC, mineral-associated organic carbon; LeNSC, non-structural carbon in leaves; BrSC, structural carbon in branches; BrNSC, non-structural carbon in branches; RoSC, structural carbon in roots; RoNSC, non-structural carbon in roots.
