PAC inhibition and reversion by GA₃ of parthenocarpic fruit-set and growth of unpollinated MT, MT-D, and MT-SP ovaries induced by NPA applied to the pedicel (A) and of MT unpollinated ovaries induced by IAA applied to the ovary (B). C, Control. NPA was applied in lanolin (1.5 mg g⁻¹), and IAA (2 μg) and GA₃ (2 μg) in 10 μL of solution, to the ovary at day 0. PAC was applied to the roots in 10⁻⁵ m solution. Data are means ± se (n = 16).
