FIGURE 5

Dynamics of perSclZ1 (A), ADL (B), Cell_VS (C), Hemi_VS (D) (perSclZ1: percentage of sclerenchyma tissue (red stained) in % of Z1 area, ADL: Acid Detergent Lignin in %DW, Cell_VS: cellulose content in %DW, Hemi_VS: hemicellulose content in %DW) as a function of sorghum internode age expressed in thermal time cumulated since their growth onset; average for 2 genotypes (G1: Biomass140 and G4: RE1xAR4) for each year (2013 and 2014), for the well-watered treatment only. Each point is the average (with standard error bars) of the three blocks. All internodes sampled at the end of the stress period and the final harvest were used (2013: 2nd and 4th ranks below the last ligulated leaf and 2014: last ligulated leaf rank and 2nd, 4th, and 6th ranks below).
