Fig. 5From: High-throughput analysis of chemical components and theoretical ethanol yield of dedicated bioenergy sorghum using dual-optimized partial least squares calibration modelsPrincipal component analysis plots distribution of chemical components and theoretical ethanol yield. Soluble sugar (a), cellulose (b), hemicellulose (c), lignin (d), ash (e), and theoretical ethanol yield (f) for calibration and external validation subsets that partitioned by sample set partitioning based on joint X–Y distancesBack to article page
