ACS activity (A) and ACC content (B) during the six stages of capsicum ripening. G, Green; B, Breaker, BR1, Breaker Red 1; BR2, Breaker Red 2; LR, Light Red; DR, Deep Red. ACS activity is expressed as nmol ACC/g fresh weight (FW)/ h and the ACC content is expressed as nmol ACC/g FW. Bars represent means (±SE) for n = 3 biological replicates for all capsicum ripening stages and n = 1 biological replicate for ripe banana and tomato (as positive controls where their levels have been similarly reported in other studies [18, 19]). The same letter indicates no difference between means as determined using the Least Significant Difference (P < 0.05).
