CASTRICINI, Ariane; COELHO, Eugênio Ferreira; RODRIGUES, Maria Geralda Vilela  e  COUTINHO, Rodrigo Cardozo. Post harvest characterization of bananas 'BRS Platina' first cycle under regulation of irrigation deficit . Rev. Bras. Frutic. [online]. 2012, vol.34, n.4, pp.1013-1021. ISSN 0100-2945.  https://doi.org/10.1590/S0100-29452012000400007.

The study had as objective the post harvest characterization of bananas cultivar BRS Platina that is a tetraployd hybrid AAAB developed by Embrapa. The crop was grown at North of Minas Gerais with reduction of irrigation water depths (L) from five months after planting. Seven treatments were evaluated with different combinations of water depth reductions (55%, 70% and 85%) during two phases of crop development (5 to 7 months and 7 to 12 months after planting) where fruits were characterized when completely yellow by: total soluble solids (tss), dropping, pulp strength, length and fruit diameter, pulp/peel ratio and color of peel (L*, C* and ºh). The total soluble solids was larger on fruits of treatments T3 and T5, where there was reduction of irrigation water depth only in the phase II (flowering) for 70% and 85% of ETc. The larger pulp/peel relationship and the resistance to drop were observed when ETc was reduced by 25% in phase III (from the beginning of fruit growth to harvest). Stronger fruit were produced when ETc was reduced about 45%. The smaller fruit dropping was verified when the reduction was 45% and 30% in phase II and about 30% on phase III. The larger fruits, as in length as in diameter, the heaviest ones were produced with no water deficit along the whole crop cycle.
