Canopy stomatal uptake of NOX, SO2 and O3 by mature urban plantations based on sap flow measurement
TL;DR: In this article, the sap flow-based approach was used to study the canopy stomatal uptake of NOX (NO, NO2), SO2 and O3 by three mature urban plantations (of Schima superba, Eucalyptus citriodora and Acacia auriculaeformis).

Suppression of nighttime sap flux with lower stem photosynthesis in Eucalyptus trees.
TL;DR: The results suggest that Js,n may act as an oxygen pathway since green tissue has a higher respiration or oxygen demand than non-green tissue and the possible benefits of nighttime water use or E by the tree.

TL;DR: Under the combined impact of sap‐flux density and sapwood area, native species presented a larger water transport at a larger DBH value, indicating that growth advantage of exotic fast‐growing species might weaken as DBH increased.

TL;DR: The present study endorses the use of sap flow measurements as a feasible tool for estimating Fst,O3, and the transition from the exposure-based toward flux-based metrics for assessing O3 risk for forest trees.
