Fig. 3From: Stress-wave velocity of trees and dynamic Young’s modulus of logs of 4-year-old Eucalyptus camaldulensis trees selected for pulpwood production in ThailandRelationship between stress-wave velocity of trees and mean dynamic Young’s modulus of logs. Number of sample 35, r correlation coefficient. Double asterisk significance at 1 % level. Mean dynamic Young’s modulus of logs was calculated by averaging the values for the first and second logs from each treeBack to article page
