Vulnerability-to-cavitation values for F. excelsior L. derived from the acoustic vulnerability curve (VC_AE) of sensor AE₁, the embolism-related VC (VC_AE-E) based on LDA and the X-ray computed microtomography VC (VC_CT)

Vulnerability value (MPa)	VCAE AE1	VCAE-E	VCCT
AE12/CT12	− 1.02	− 1.03	− 1.13
AE50/CT50	− 2.30	− 2.37	− 2.34
AE88/CT88	− 4.32	− 4.61	− 4.82

Water potential at 12, 50 and 88% cumulative acoustic emissions (AE₁₂, AE₅₀ and AE₈₈), and 12, 50 and 88% µCT detected embolism formation (CT₁₂, CT₅₀ and CT₈₈) for F. excelsior L. of sensor AE₁, LDA and µCT
