Soluble sugar, cell wall, hemicellulose and lignin contents in sugarcane. a Soluble sugar presented as a percentage of dry weight as determined by HPLC. b % Ratio of the three major cell wall components. As determined using Klason lignin, HPLC and HPAEC quantification. Values reported as a percentage of total cell wall components. c % Ratio of non-cellulosic sugars, otherwise known as mol%, as determined by HPAEC. Values reported as a percentage of total non-cellulosic components. d Acid-soluble (ASL) and acid-insoluble (AIL) lignin fractions. As determined in the Klason lignin methodology and subsequent spectroscopy of the hydrolysate. KQ228 and Q208 refer to the Saccharum spp. hybrid genotype. Abbreviations, TI: top internode; MI: middle internode; BI: bottom internode; first visible dewlap leaf: L1; fifth visible dewlap leaf: L5; R: root. Letters above each bar indicate the presence of a significant difference between values within the same genotype. Error bars ± 1 S.D. from biological triplicates. Significance was calculated via one-way ANOVA, with the post hoc LSD test to separate statistically dissimilar groups. Statistical analysis was measured separately within each genotype
