Figure 3: Daily time course of percent loss of conductivity (PLC) in the distal branches and the relationship between PLC and leaf water potential before dawn (ψpre).
From: The dynamics of carbon stored in xylem sapwood to drought-induced hydraulic stress in mature trees
(A) Daily time course of PLC in Hibiscus glaber. (B) Daily time course of PLC in Ligustrum micranthum. (C) The relationship between PLC and ψpre in Hibiscus glaber. (D) The relationship between PLC and ψpre in Ligustrum micranthum. In panels (A) and (B), open and closed symbols denote the control and irrigated trees, respectively. See the legend of Fig. 1 for the timing of the water supply. In panels (C) and (D), open and closed symbols show data during the dehydration process and during the rehydration process following the addition of water, respectively. The curves are fitted with a double-sigmoid function.
