Figure 6From: A holistic high-throughput screening framework for biofuel feedstock assessment that characterises variations in soluble sugars and cell wall composition in Sorghum bicolorFTIR prediction of cell wall digestibility. (A) Distribution of cell wall digestibility (μg.mgDW-1.h-1) from a diverse collection of S. bicolor ecotypes grown under a range of different conditions and harvested at varying developmental stages. A fitted normal distribution has been overlaid. (B) PLS prediction of cell wall digestibility (D; μg.mgDW-1.h-1) in an independent test set. Predictions are plotted against the known reference values for each sample. Calibration samples (○) and independent validation samples (•) were overlaid on a target line (y = x). The coefficient of determination (R2) and root mean square error (RMSE) for each sample set are inset. DW, dry weight; FTIR, Fourier transform infrared; PLS, partial least squares; RMSE, root mean squared error.Back to article page
