Free ACC (A), ACC conjugate (B), and ACO enzyme activity (C) of pea pericarps with seeds and deseeded pericarp treated with IAA or 4-Cl-IAA. Pea pericarps were intact, split (SP), or split and deseeded (SPNS), and treated with 50 μM IAA or 4-Cl-IAA in aqueous 0.1% Tween-80, or aqueous 0.1% Tween-80 (SPNS control) 12 h after deseeding. Assays were completed on tissues 12 h after the hormone treatment. Data are means ±SE n=3, except for intact, SP, and SPNS free ACC and ACC conjugate analysis, where n=2. Comparisons were made using student’s t-test. *Means are significantly different from that of SPNS at P<0.05. °Means are significantly different from that of 4-Cl-IAA at P<0.05.
