Table 1.
List of accessions used, with local name, origin and fruit traits, and years of evaluation in the experiment.
Table 2.
General ANOVA for the content of ascorbic acid (AAC) and total phenolics (TP) and specific ANOVA corresponding to each ripening stage for AAC, TP, total red carotenoids (TCR), and total yellow/orange carotenoids (TCY/O).
Table 3.
Average content in ascorbic acid (AAC, mg·100 g-1 fresh weight) estimated in the unripe and fully ripe fruits from the peppers studied, evaluated under organic and conventional conditions and regression coefficient (β) based on environmental means.
Table 4.
Average content in total phenolics content (TP, mg chlorogenic acid equivalents·100 g-1 fresh weight) estimated in the unripe and fully ripe fruits from the peppers studied, evaluated under organic and conventional conditions and regression coefficient (β) based on environmental means.
Table 5.
Average content in total red carotenoids and yellow/orange carotenoids (TCR and TCY/O, mg·100 g-1 fresh weight) estimated in the unripe and fully ripe fruits from the peppers studied, evaluated under organic and conventional conditions and regression coefficient (β) based on environmental means.
Fig 1.
Comparative study of the content of ascorbic acid (AAC, upper, mg·100 g-1 fresh weight) and total phenolics (TP, bottom, mg·100 g-1 fresh weight), in organic (○) and conventional (Δ) growing systems.
The oblique lines included in the graph represent slope 1 (continuous line, ratio fully ripe/unripe = 1, increase 0% with ripening) and slope 2 (discontinuous line, ratio TP fully ripe/TP unripe = 2, increase 100% with ripening).
Fig 2.
Comparison among accessions at the unripe stage considering ascorbic acid content (AAC) and total phenolics (TP) under organic (upper) and conventional (bottom) growing systems.
Texture of columns, based on β parameter, indicates better response to organic (Org.), conventional (Con.) or stable behaviour (Sta.). Bars on the top of columns indicates standard error intervals.

Comparison among accessions at the fully ripe stage considering ascorbic acid content (AAC), total phenolics (TP) and total carotenoids (TCR+TCY/O) under organic (upper) and conventional (bottom) growing systems.
Texture of columns, based on β parameter, indicates better response to organic (Org.), conventional (Con.) or stable behaviour (Sta.). Bars on the top of columns indicates standard error intervals.
