  1. Lignin content (total and klason) was determined by NIR-PLSR models. Lignin-derived S and G monomers and ratio were calculated by pyrolysis analysis. Each repetition corresponded to 20-polled plants. Percentage was calculated by 20 mg of lignin/ 100 mg dry mass. Anova statistic test: *, P < 0.01; **P < 0.001.
