Production locality affects mango fruit quality.

Differences in mango (cv. Kensington Pride) fruit quality under commercial and research conditions have frequently been noted. To assess the potential for production conditions to influence fruit quality, Kensington Pride fruits were obtained from 2 adjacent sites from an orchard on shallow nodular yellow podzolic soil in tropical North Queensland, Australia; 1 block of trees grew on soil with river gravel (site 1) and the other without gravel (site 2). Fruits were also obtained from trees on a gleyed podzolic soil (site 3) in subtropical south-east Queensland. Fruits were harvested weekly for 4 weeks; quality was determined after ripening at 22 deg C and after storage at 10 deg for 4 weeks. Eating quality and percentage dry matter increased, while days to a firmness of 6 N (eating soft) decreased with later harvests. Fruits from site 3 (cooler growing conditions, rain during the harvest period) had acceptable eating quality at a lower dry matter than fruits from sites 1 and 2. The percentage of

 green colour on the skin (GS) at ripeness was higher at harvest 2 in fruits from sites 1 and 2, but was lower at harvest 4 in fruits from all sites. Disease incidence in fruits ripened without storage was higher in site 3 fruits; rots (caused mainly by Colletotrichum spp.) increased (site 3 only) and stem end rots (caused mainly by Dothiorella spp.) decreased with later harvests. Fruit firmness and GS decreased during storage at 10 deg , but fruits from site 3 were generally softer, with higher GS, than those from the other sites. Chilling injury was higher in fruits from site 3.
