LOPES, Osdnéia Pereira et al. Protection against sunburn of pineapple fruits submitted to different irrigation levels. Rev. Bras. Frutic. [online]. 2014, vol.36, n.3, pp.748-754. ISSN 0100-2945.  http://dx.doi.org/10.1590/0100-2945-273/13.

The purpose of this study was to evaluate the use of solar protection against sunburn and the effect of different irrigation levels on fruit quality of pineapple 'Pérola'. The experiment was conducted in the experimental area in Janaúba, MG. The irrigation system used was drip and the amount of depth water applied was calculated based on the class-A evaporation pan (PAN). The protection of fruits against sunburn was made after floral closure. The design was randomized blocks, according to the split plots 5 x 4, with five irrigation depth (30%, 50%, 70%, 100% and 150% of PAN) and the subplots are 4 types of protections: newspaper, brown paper bag, TNT white nº 40 and lime solution 10% and the control, with four replications. It was evaluated the percentage of fruits with symptoms of sunburn, pulp firmness, total soluble solids (TSS), total titratable acidity (TTA), pH and TSS/TTA. Fruits protected with TNT showed a lower percentage of sunburn. The irrigation depth regarding 77% of PAN associated with TNT or lime protection resulted in higher TSS values.
