Near Infrared Spectroscopy: Rapid and Accurate Analytical Tool for Prediction of Non-Structural Carbohydrates in Wood

Abstract

HIGHLIGHTS NIR spectroscopy has yielded promissory estimates of the NSC in wood. NIR signatures taken from wood powders are more informative for NSC modeling. NSC predictions from wood disc spectra provided satisfactory responses. Breeders can understand the resilience of trees using NSC estimates by NIR.

The mechanisms and prediction of non-structural carbohydrates accretion and depletion after mechanical wounding in slash pine (Pinus elliottii) using near-infrared reflectance spectroscopy

“…We found we could accurately estimate total NSC and starch distribution in plant tissues using NIR spectroscopic models after variable selection; similar results were reported by Ramirez, Posada, Handa, Hoch, Vohland, Messier and Reu [ 26 ]. Rosado, Takarada, Araújo, Souza, Hein, Rosado and Gonçalves [ 22 ] also investigated the physiological responses of plants to different environmental stresses, but in Toona ciliata M. Roemer var. australis wood grown in southern Brazil.…”

“…This disagreement might be attributed to the methods of measuring NSC concentrations in plant tissues [ 6 ], which are time-consuming and expensive and limit the scope for NSC research on large numbers of samples. Near infrared reflectance (NIR) spectroscopy is a rapid, cost-effective and high-throughput technique that can be used for measuring organic compounds in plant tissues [ 21 , 22 ]. For instance, NIR based models yielded promising predictions for N, neutral detergent fiber, lignin and cellulose concentrations in leaves of 17 different woody species [ 23 ].…”

“…The starch concentrations in Sorghum bicolor (sorghum grain) and Rumex obtusifolius roots have been also successfully predicted by NIR [ 24 , 25 ]. Encouraging results were reported for predictive models to estimate the NSC in Toona ciliata wood from NIR spectra directly recorded on wood discs and milled wood samples [ 22 ]. Furthermore, spectroscopic determination of NSC concentration in different tissue types with seasonal change of different tree species was also achieved [ 26 ].…”

DEVELOPING NEAR INFRARED SPECTROSCOPIC MODELS FOR PREDICTING DENSITY OF Eucalyptus WOOD BASED ON INDIRECT MEASUREMENT

“…In general terms, the spectral signature can be used for qualitative and quantitative evaluation of the chemical composition of a particular compound present in the sample, or even to estimate the physicochemical properties of a material (Sandak et al, 2016). For instance, Rosado et al (2019) have applied NIR technology for estimating the amount of non-structural carbohydrates in Toona ciliata wood based on spectral signatures.…”
