Title: Progress with Deployment of Three Instruments for Non-destructive Evaluation of Eucalypt Wood Properties
Abstract: As a result of increasing demands for wooden products,enhancing both theyield and quality of wood obtained from Eucalyptus plantations in China is an effective method to reduce shortages of raw materials for such products.Developing rapid and non-destructive methods for screening the wood properties of large numbers of trees at early ages will help select trees with superior genetic qualities and shorten the breeding cycle.This paper reviewed principles and applications of three methods for such screening: Pilodyn,Fakopp and CIRAD-Foret growth strain gauge.These methods have been widely used for assessment and prediction of wood properties in Eucalyptus species.According to previous studies,Pilodyn penetration and outer-wood density have significant negative correlations;modulus of elasticity and acoustic wave velocityas determined by using the Fakoppinstrument have shown positive correlations;and,longitudinal growth stress(measured with the CIRAD-Foret growth strain gauge method) is useful for predicting some wood defects.It is recommended that future research focus on strengthening applications of nondestructive testing technology in eucalypt cultivation,and enhances use of these technologies for early prediction and screening for genetic quality in order to improve the quality of wood obtained from eucalypt plantations.
