Produção e qualidade da manga Tommy Atkins após aplicação de paclobutrazol.

Abstract

The objective of this work was to determine production and quality of mango fruits after paclobutrazol application (PBZ). The experiment was carried out in a commercial mango plantation of the Mossoro Agroindustry (MAISA), located at the municipal district of Jaguarana, Ceará, Brazil, from January to December of 1999. The floral induction was made by applying 0, 1000 mg. L1 and 1500 mg. L1 of paclobutrazol in the plants followed by two Ieaf applications of ethephon, in the concentrations of 1mL.L1, and by five leaf applications of 4% KNO, Paclobutrazol, at the rate of 1000 and 1500 mg.L, increased the number of fruits/plant in the order of 280% and 250%, respectively. The estimated production of the control plot was around 2,39 t.ha1 with 9,06 and 7,83 L.ha1 in the treatments with the application of 1000 and 1500 mg.L1 of paclobutrazol. The average soluble solids content was 11,09% and did not show any difference among treatments. The total acidity was in the order of 0,45% (malic acid) and also showed no difference among treatments. The paclobutrazol increased productivity but did not affected the quality of post harvested mango fruits, cv. Tommy Atkins.
