Xylem transport of root‐derived CO2 caused a substantial underestimation of belowground respiration during a growing season

DP Aubrey, RO Teskey - Global Change Biology, 2021 - Wiley Online Library
Previous research has indicated that a potentially large portion of root‐respired CO2 can
move internally through tree xylem, but these reports are relatively scarce and have …
