Effect of preharvest bagging and of embryo abortion on calcium levels in 'Kensington Pride' mango fruit.

In this trial on 6-year-old trees near Gatton, Queensland, Australia, mango cv. Kensington Pride fruits were bagged at 41, 25 or 9 days before harvest. No statistically significant differences in either skin or flesh calcium concentration were found between the bagged (plastic or paper) and unbagged fruits. Postharvest weight loss was enhanced and shelf life reduced in the plastic-bagged fruits. In an ancillary study, calcium concentrations in Kensington Pride nubbins (seedless fruit) were compared with those in seeded fruits, since it has been shown with apple fruit that greater seededness is positively correlated with increased flesh calcium concentrations. Conversely, however, calcium concentrations in the flesh of mango nubbins were found to be significantly higher (0.80 mg/g dry weight) than those in seeded fruits (0.58 mg/g dry weight) of similar size.
