Control and Reaction Wood induced potgrown trees of eight genotypes.A Glucan composition expressed as a percentage of dry matter (DM). B Lignin composition expressed as a percentage of DM. C Glucose yields from enzymatic saccharification presented as grams of glucose released per gram of glucan present in the biomass. Error bars represent standard error (n = 3 trees). Full mass closed compositional tables are available in supplementary information. D Midpoint 20-μm transverse sections of a single stem from pot-grown genotypes ‘Shrubby’ and ‘K8-428’. Stained in 1% Chlorazol Black E in methoxyethanol (black – binds specifically to the gelatinous layer within the G-fibres of tension wood [21]) Scale bar = 5 mm. * Significant difference (t-test, p < 0.05).
