Topic:  The use of near-infrared reflectance spectroscopy to detect ­tension wood in Eucalyptus globulus

University of Melbourne


Use of near-infrared (NIR) scanning technology provides a fast and cost-effective way of predicting various commercially important wood properties.

Maximilian’s research focuses on the presence of tension wood that causes irrecoverable collapse in Eucalyptus globulus. Tension wood can cause problems in sawing and drying of boards, leading to increased processing costs and reduced product value. The ability to detect the occurrence of tension wood in standing trees by non-destructive methods such as NIR scanning of wood samples would be a valuable tool for those involved in developing solid-wood products from plantation-grown E. globulus.

The objectives of this research are:

•    To define the limits of Microfibrilar Angle (MFA), wood density and cellulose content variation to be able to specify the occurrence of non-recoverable collapse that has a negative impact on the drying and sawing process of Eucalyptus globulus wood.

•    To determine the extent to which these can be used to develop an NIR calibration for the presence of tension wood.

•    To investigate likely influences of genetic, site and silvicultural factors on the incidence and severity of tension wood development in E. globulus  trees.

It’s expected this project will result in a reliable NIR calibration to predict the occurrence of tension wood in E. globulus.
