Light fruit set of navel oranges and—to a lesser degree—of Valencia oranges often occurs and growth regulators tested in California in the past have failed to increase the set. However, certain gibberellin treatments—in preliminary experiments—have increased fruit set on lime, lemon, and orange trees.
