UPDATE ON NEW MANGIFERA SPECIES IN FLORIDA, USA
Several Mangifera species have been collected and are under evaluation at Fairchild Tropical Botanic Garden in South Florida, FL, USA over the past 15 years. M. odorata, M. casturi, M. lalijiwa, M. quadrifida, M. laurina, M. rubropetala and a putative M. odorata/M. foetida hybrid have been grafted successfully on Turpentine rootstock and trees have been grown in the field for 6 to 14 years. All of these species have bloomed and fruited with reasonable reliability over this time. In addition, many of the species have withstood temperatures as low as -1°C for more than 5 hours with only minimal damage. Temperature does not appear to be a reliable inducer of bloom for these species growing in the field. Additional investigation is necessary, but Mangifera species also have shown a high degree of anthracnose tolerance under Florida conditions, but many have shown severe susceptibility to leaf and twig bacteria infection. The fruit of each species is unique in terms of color, appearance and eating quality, and all have potential as fresh fruit given proper selection of clones with superior fruit quality. M. griffithii, M. quadrifida, M. merilli and M. lalijiwa have performed better with M. casturi as an interstock. M. caesia, M. foetida, M. pajang and some unidentified species have not been successfully grafted on M. indica and no successful interstock has been found.
