The vulnerability of xylem vessels to water stressinduced cavitation was studied by measuring hydraulic conductivity and ultrasound acoustic emissions [AEs) in Fagus sylvatica L. f. purpurea (Ait.) Schneid. and Populus balsamifera L.. The occurrence of xylem embolism in summer was investigated in relation to leaf water potential and stomatal conductance. Populus was extremely vulnerable to cavitation, losing functional vessels due to embolism at water potentials lower than —0.7 MPa. Fagus… CONTINUE READING
