SEQUENCE OF FLOWERING AND FRUIT SETTING I N AN INFLORESCENCE OF CITRUS CULTIVARS

Flowering sequence and fruit setting were examined in a raceme inflore scence of orange, pummelo and grapefruit cultivars. The flowering sequ ences in an inflorescence having 4-6 flowers of orange, pummelo and gr apefruit cultivars revealed similar patterns. The apical flowers opene d first followed by basal flowers and then flowers at the middle part of the inflorescence. The subapical flowers opened at the end of flowe ring period. The frequency of fruit setting in an inflorescence was no t affected by the flowering sequences. Flowers among the second to the fourth from the apical flower readily set at higher frequency than th e apical and basal flowers.
