Quantification of stem embolism in Silver birch. Percentage of cavitated stem (PCS) values from a Silver birch sapling (sample D) as a function of time. The inset shows a close-up of data points 4-7, with the vertical dashed line indicating when watering of the sample was resumed. The numbers in parentheses are estimates of the number of cavitated vessels in the observed slice. The dried sample (Figure 7f) had a PCS value of 61% and approximately 600 vessels.
