Rapid Assessment of Chemical Composition, Calorific Value and Specific Gravity of Hybrid Poplar Wood Using Near Infrared Spectroscopy.

摘要

With a growing interest in renewable energy, hybrid poplars (HP) could be optimized for bioenergy production via direct combustion or conversion into cellulosic ethanol. This project, in collaboration with Greenwood Resources Inc., aims at developing analytical tools for rapidly assessing and screening traits of HP that are relevant to bioenergy production. In particular, the ability of near infrared spectroscopy for determining the chemical composition, calorific value and specific gravity of HP was evaluated. The objectives of this study were: (1) to develop NIR calibration models for assessing the chemical composition of HP, (2) to develop NIR calibration models for assessing both calorific value and specific gravity of HP wood and (3) to evaluate whether parentage, age and growing site of HP trees affect the calorific value and specific gravity of the wood.
