Plant and Soil as Hydraulic Systems

Hydraulic constraints on plant gas exchange

Stomatal conductance (gs) and transpiration (E) are often positively correlated with the hydraulic conductance of the soil–leaf continuum (ks–l). Interaction between gs and ks–l helps regulate water potential (9) of leaves. When soil and plant 9 decreases during water stress, ks–l decreases. A well-documented cause of the decrease in ks–l is xylem cavitation. The interaction between k and 9 in ...
