Abstract

Gibberellic acid is registered and recommended in California for certain uses (particularly in delaying rind and fruit maturity) on navel oranges and lemons. Favorable responses have also been obtained on limes and mandarins, but our present knowledge is insufficient to warrant registration or recommendation for use on these fruits. So far, we do not know how to take advantage of the delayed softening and aging of Valencia orange and grapefruit rind tissue without obtaining considerable regreening. The influence of GA3 on retention of young fruit has potential value, but no practical method has yet been devised to avoid phytotoxic responses.
