From: Metabolomics of dates (Phoenix dactylifera) reveals a highly dynamic ripening process accounting for major variation in fruit composition

PC1 from DS2-mature is associated with the ripening process. a PC1 scores from DS2-immature. Fruits from varying stages of ripening from the same sample are shown on the same line. Each fruit is labelled with an identifier featuring a letter indicative of its extent of ripening relative to the other fruits within the sample as judged by eye. The ordering of the letters is well captured by the PC1 scores and occasional discrepancies occur when the fruits featured very similar PC1 scores. Density analysis of the PC1 scores, showing on top of (a) indicates that the fruits can be assigned to three developmental classes, denoted as class 1 (light green), class 2 (light pink) and class 3 (light blue) by increasing ripening maturity. b An OPLS-DA classifier trained on class 2 versus 3 was used to calculate class prediction scores for all DS2 samples including the batch1&2 samples which were measured in separate batches once with dates from the first sample collection and again with dates from the second sample collection. c A scatter plot of PC1 scores and OPLS-DA class prediction scores from the DS2-mature samples indicates a significant correlation
