Fig. 3From: Hydraulic properties and embolism in small-diameter roots of five temperate broad-leaved tree species with contrasting drought toleranceNumber of roots in classes of root-specific conductivity k s (class width = 5 kg MPa−1 s−1 m−1) in the five tree species. Gray bars indicate roots which were considered to be “high-conductivity roots”. n number of roots examined per speciesBack to article page
