Resumo
The pineapple crop has a permanent demand for water, variable and dependent on their stage of development, which may affect the production and fruit quality. This study aimed to evaluate the chemical quality of fruits Smooth cayenne pineapple submitted to different levels and frequency of water replacement in the soil. We used a randomized block design in a 4 × 2 factorial arrangement, consisting of four levels of soil water replenishment (50%, 75%, 100% and 125% of crop evapotranspiration) and two irrigation frequencies (1 and 3 days) with four replications. We evaluated the parameters: juice yield (RS), hydrogen potential (pH), total soluble solids (SST), titratable acidity (ATT), SST/ATT relationship, ascorbic acid (AA). It was observed that the blades and irrigation frequencies did not affect the juice yield (RS) and ascorbic acid (AA), the increase of the blades irrigation influenced positively the quality of the fruit as it increases the values of total soluble solids (SST) decreases the acidity (ATT), raises the relationship SST/ATT and hydrogen potential (pH).
