Abstract

The influence of flowering index on the equatorial
mean fruit diameter was studied at harvest time. The experiment
was conducted in a grapefruit (Citrus paradisi Macf) orchard
of Marsh cultivar grafted on sour orange (Citrus aurantium
Linn). The relationships between both indicators were
determined through Chi Square test and Spearman correlation.
Results enabled to conclude that the equatorial mean fruit
diameter at harvest time is closely and negatively related to
flowering intensity, and even at flowering levels of up to 50 %
reproducing sprouts, the greatest equatorial mean diameter
percentage corresponded to 99-105 mm; then, fruits are
classified as big ones (commercial size 36), meanwhile those
derived from a higher intensity than 50 % got 95-77 mm diameter
at harvest time, mid size (commercial size 40).
