Table 2 Performances of PLSR regression models based on full bands

Constituent	LVs	R ²_C	RMSEC	R ²_P	RMSEP	RPD
Hemicellulose	16	0.850	0.010	0.780	0.012	2.131
Cellulose	17	0.918	0.008	0.836	0.012	2.466
Lignin	17	0.906	0.006	0.802	0.008	2.248

LVs means the number of latent variables, R ²_C and R ²_P indicate the determination coefficients for the calibration and prediction, respectively, RMSEC and RMSEP represent the root mean square errors for the calibration and prediction, respectively, and RPD denotes the ratio of performance to deviation (similarly hereinafter)
