Effect of seeds and hormones on pericarp growth. A, Effects of pericarp splitting (SP), seed removal (SPNS), and treatment of SPNS with GA₃ (GA), 4-Cl-IAA (4-Cl), and GA₃ plus 4-Cl-IAA (GA+4-C1) on pea pericarp growth. Pericarps at 2 DAA were split (SP) or split and deseeded. GA₃ and/or 4-C1-IAA or 0.1% (v/v) Tween 80 (SP, SPNS) were applied immediately after deseeding and daily thereafter (50 μm; 30 μL at 2 and 3 DAA; 40 μL at 4, 5, and 6 DAA). Data are means ± se (n = 5). B, Representative pericarps harvested at 7 DAA are shown in picture.
