Fig. 1. Principle component analysis (PCA) of 18 important volatile compounds measured in full ripe ‘FL 47’ tomatoes. Fruit were pre-treated by MeJA/MeSA and/or chilling
(5 C, 9 d) at breaker stage. (a) PCA scores plot and (b) PCA loadings plot. Only loadings ending up between a black dashed circle with a radius of 0.7 and a red solid circle with a
radius of 1.0 are worthwhile considering. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
