Diversity of chemical and physical properties of 59 Jerusalem artichoke accessions from six typical regions. a Chemical component. b Biomass digestibility. c Original near-infrared spectra. d Scores distribution of principal component analysis. For levels of each analyzed quality specification among the JA samples, capital letters indicate significant differences among six typical regions at P < 0.001. Dry matter is the dry Jerusalem artichoke sample before soluble sugar extraction. Log(1/R) is used to relate near-infrared reflectance to concentration of absorbing material.
