(for conventional) report the biplots of the PCA models calculated for each
cropping system in each year of cultivation. To better highlight the
associations between physiological behavior, final fruit and total
dry weight of the six cultivars during the crop growth cycle, the
values corresponding to all four growth stages are represented for
each physiological parameter. In both the PCA models calculated for
each of the 2 years, the two first components always represented
more than half of variation in the datasets, with PC1 ranging from
30.14% to 43.69% and PC2 from 24.0% to 27.51%. In both years and
in each system, it was not possible to identify clear separations into
clusters, therefore the results are described in relation to the two
important parameters, such us final fruit and total dry weight. In
general FDW and TDW, as expected, are always highly associated
in all years and systems, since they are close each other in all the
four plots
