- Abstract
Several factors may interfere in the cycle of the pineapple crop and the quality of the fruits produced, among them the cultural treatments, especially with regard to the treatment of floral induction. The harvest period and the uniformity of the fruits can be regulated by the use of floral inducers. In this context, the objective of this work was to evaluate the influence of floral induction (FI) on different days after planting (dap) on the characteristics of pineapple fruits of the cultivar Pérola cultivated in the city of Araguatins/TO. The experimental design was in randomized blocks. The treatments consisted of 4 periods of FI (T1-305dap, T2-320dap, T3-335dap, T4-350dap) and 5 replicates. The duration of the phases between planting at harvest, Total Soluble Solids (TSS), Total Titratable Acid (TTA), TSS/TTA ratio, fruit weight with and without crown, fruit diameter and yield were evaluated. The phase comprised between induction-flowering ranged from 41 to 43 days and flowering-harvest from 100 to 104 days. The total culture cycle ranged from 450 to 492 days. The weight of fruit with and without crown was not affected by treatments, ranging from 1,388 to 1,552 g, and from 1,381 to 1,489 g, respectively. As for the chemical characteristics of the fruits, only the TSS was influenced by the different treatments, and the T4 allowed the development of fruits with higher °Brix. The productivity was not influenced by the different treatments and ranged from 39,413 to 44,794 kg.ha-1.
