Ovaries from emasculated flowers were treated with solutions (20 μL per ovary) containing different amounts of GA1 or GA20, or with mixtures of GA20 (2 μg) and LAB (1, 5, and 10 mm), and developed fruits (those having a weight higher than 1 g) collected 65 to 68 d later. Control ovaries were treated with an equal volume of solvent solution. Values of diameter and weight are means of those developed fruits. At each column, values with a different letter were significantly different (P < 0.05).
