Interactive effects between response variables and experimental factors^a

Response variable	Factor
	Plant species	Anatomical fraction	Particle size
AcIR content	< 0.001	0.03	0.11
Glucan content	< 0.001	< 0.001	0.02
Xylan content	< 0.001	< 0.001	0.01
Xylose yield	0.05	< 0.001	0.80
Glucan digestibility	0.34	< 0.001	0.12
Glucose mass release	< 0.001	0.02	0.45

^aThe significance of interactive effects is represented by the P-value. The significance (P-value) of the influence of the experimental factors (plant species, anatomical fraction, and particle size) on response variables (AcIR content, glucan content, xylan content, xylose yield, glucan digestibility, and glucose mass release) is displayed. The P values are calculated from individual ANOVA tests and are displayed for each interaction.
