Figure 5. The percentage of embolized xylem area (black) and water potential (blue) plotted against time for a leaf of Lindera benzoin rehydrated at 20% embolized xylem area (A), in which only midrib and a few major veins had experienced embolism (B) and a leaf of the same species that was rehydrated when 35% of the xylem was embolized (C). The vertical dashed lines in A and C indicate the period between rehydration and the point at which the Ψ on the second dehydration had declined to the Ψ when the branch was first rehydrated. The red box in C surrounds the percentage of embolized xylem area that occurred prior to Ψ declining to the value recorded when the branch was rehydrated. In B the area of leaf imaged is shown on the left and the embolism events observed when rehydrated shown on the right, the scale bar depicts the Ψ at which each embolism event occurred.
