Abstract : An instance of natural parthenocarpy in mango, cv. Thambva, is reported. In an attempt to induce parthenocarpy chemically, emasculated flowers were sprayed in early February with GA at 100 p.p.m., NAA at 50 p.p.m. or water, and set fruits were sprayed twice with NAA at 40 p.p.m., on 29 February and 20 March. Initial fruit set was highest (5.3%) with GA treatment, compared with 0.7% for untreated controls; fruit retention was also highest with GA, but only 2 matured out of 83 initially set. These contained a small degenerate ovule at one end and the stone was flat and compressed, weighing only 7 g, compared with 148 g normal fruits. Fruit size and quality, however, were little affected.
