Article Title: On-The-Go VIS + SW − NIR Spectroscopy as a Reliable Monitoring Tool for Grape Composition within the Vineyard
doi: 10.3390/molecules24152795
Figure Lengend Snippet: Regression plots for the total soluble solids ( A ), anthocyanins ( B ) and total polyphenols ( C ) using the best Partial Least Squares (PLS) models generated from on-the-go grape clusters spectral measurements. (blue color) 10-fold cross validation; (red color) external validation. (■: 11 August; *: 24 August; ●: 18 September; ▲: 28 September). Solid line represents the regression line and dotted line refers to the 1:1 line. Prediction confidence bands are shown at a 95% level (dashed lines).
Article Snippet: The partial least squares (PLS) Toolbox (version 8.1, Eigenvector Research, Inc., Manson, WA, USA) was used for principal component analysis (PCA) and partial least square regression (PLS).
