Table I. Xylem pressure at 50% loss of hydraulic conductance (P50) for three woody species as determined by two centrifuge techniques and microCT.
Within each row, different letters indicate significant differences (P < 0.05) across techniques. Values are means ± se (n = 3–5 for Cavitron and static centrifuge measurements).
