Determination of water-soluble carbohydrates by near-infrared spectroscopy for canola, maize, and sorghum stem fractions.Near infrared spectroscopy (NIRS) was evaluated as a rapid and non-destructive method for determining the concentration of water-soluble carbohydrates (WSC) in stem fractions for winter canola (Brassica napus L.), maize (Zea mays L.) and sorghum (Sorghum bicolor L. Moench) crops.  For each crop at different growth stages, stem WSC concentration was determined using NIRS, and benchmarked against the anthrone reagent method, chemical lab analysis.  Partial least squares regression was implemented to associate the WSC predicted via NIRS relative to those obtained by laboratory analysis.  The NIRS spectroscopy is a reliable method for WSC determination in stem tissues on these major field crops.
