| Experiment I | |||
| Control | 9 /12 | 4.6a | 39.1a |
| GA1 | 10 /12 | 4.4a | 32.5a |
| GA20 | 10 /12 | 4.4a | 33.9a |

| Control | 12 /15 | 4.4a | 40.9a |

| LAB (5 mm) + GA1 | 12 /12 | 4.1a | 36.1a |
Ovaries from emasculated flowers were treated with solutions (20 μL per ovary) containing GA1 (2 μg), GA20 (2 μg), or mixtures of GA1 and GA20 and LAB (1 and 5 mm), and developed fruits (those having a weight higher than 1 g) were 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 of developed fruits. At each column, for each experiment, values with a different letter were significantly different (P < 0.05).
