During the 1995/96 season, 30 uniform mango trees (cv. Kensington) in Ayr, North Queensland (20 deg S) had branches thinned to a single fruit and girdled to provide 30, 60 or 120 leaves/fruit above the girdle. Control branches were not thinned or girdled and had approximately 40 leaves/fruit. Increasing the leaf:fruit ratio to 120 leaves/fruit increased fruit size, reduced fruit pulp Ca concentrations, advanced maturity (as indicated by percentage dry matter and pulp colour) and reduced the number of days to ripen at 22 deg C (shelf life). Decreasing the leaf:fruit ratio to 30 decreased fruit size, increased pulp Ca concentrations, delayed maturity, increased shelf life and improved storage potential by reducing chilling injury. Increasing leaf:fruit ratios to 60 increased fruit size without reducing fruit Ca concentrations, and increased fruit shelf life. Fruits from girdled branches had 20% less green skin when ripe and increased incidence of blush and disease. Increases in fruit size were ass

ociated with increased lenticel spotting.
