Abstract
Self-pollination, emasculation and gibberellic acid (GA) were used to study translocation patterns of l4C-metabolites during flowering and fruiting in calamondin (Citrus madurensis Lour.). Radioautographs showed similar translocation patterns with self-pollination and GA. GA and self-pollination resulted in a considerably stronger mobilization of 14C-metabolites to young ovaries and developing fruits than when flowers were emasculated and no further stimulus provided. The movement of l4C-metabolites to fruits, especially in the 3-week period after anthesis, appeared essential for fruit set and development.Keywords
