Treatment of Green (G, left) and Breaker (B, right) harvested capsicum with 100 μL/L ethylene or 500 nL/L 1-MCP (for 24 h). Untreated control fruit were also prepared for both stages. A) Ripening of G and B treated fruit during storage after treatment. Representative images are shown. The scale at the bottom right of the pictures is 1 cm. B) The extractable colour (ASTA units) from each treatment and DAT (days after treatment). Asterisks adjacent to symbols indicate means were significantly different compared to the respective control at each DAT as determined by a Duncan’s Multiple Range Test (P < 0.05) (Additional file 4: Table S2 for details). Means are n = 3 biological replicates (±SE).
