- Abstract
The brazilian northeast is characterized by limited water unavailability, both in quantitative and qualitative terms. Therefore, high salt waters are applied to assure food production in the region. Thus, some strategies need to be adopted to mitigate the salt effect on grown plants. In this context, this study aimed to evaluate the yield and post-harvest quality of sour passion fruit 'BRS Rubi do Cerrado' under saline waters and H2O2 application on leaves. The experiment was carried out using drainage lysimeters under greenhouse conditions in the municipality of Campina Grande (state of Paraiba in Brazil). The design was completely randomized in splitplot plots, with water salinity levels ECw (0.6, 1.2, 1.8, 2.4, and 3.0 dS m-1) considered the plots and concentrations of H2O2 (0, 15, 30, and 45 µM) considered the subplots, with three replicates. Exogenous application of H2O2 at 30 µM mitigated the adverse effects of salt on the number of fruits and shell thickness of sour passion fruit. The exogenous application of H2O2 on sour passion fruit production mitigates the negative effects caused by saline water on polar diameter, slurry yield, and weight.
