( Clark et al., 2004 ; Gan and Amasino, 1995 ). In some species, the application of gibberellic acids (specifically GA 4+7 ) reduces postproduction losses by preventing leaf senescence ( Han, 1997 ; Ranwala et al., 2003 ; Ranwala and Miller, 1998

Gibberellic acid (GA 3 ) has been applied to citrus fruit since the 1950s to delay peel senescence and prolong on-tree storage ( Coggins, 1981 ; Davies, 1986 ; El-Otmani et al., 2000 ). Application of GA 3 does not typically affect internal
