Table 1 Vulnerability to drought-induced embolism values in F. excelsior L. derived from the acoustic vulnerability curve (VCAE) measured with sensor AE1 and sensor AE2

From: X-ray microtomography and linear discriminant analysis enable detection of embolism-related acoustic emissions

Vulnerability value (MPa) AE1 AE2
AE12 − 1.02 − 0.88
AE50 − 2.30 − 1.73
AE88 − 4.32 − 3.98
AE100 − 5.62 − 5.62
