Antifungal potential of Aloe vera in vitro and its use as preharvest treatment to maintain the quality of blueberries during storage

| Sumario: | [EN] The postharvest life of most fruits and vegetables is limited by fungal proliferation. In this study, Aloe vera gel was tested at different concentrations to evaluate its antifungal potential against five fungi—Rhizoctonia solani, Curvularia hawaiiensis, Botryotinia fuckeliana, Penicillium italicum, and Verticillium dahliae—which are responsible for significant losses in staple agricultural products such as potatoes, cereals, fruits, and vegetables. The best results were observed for V. dahliae, with complete (100%) and partial (70%) mycelial growth inhibition at 200 and 100 mL/L, respectively. Satisfactory inhibition (>50%) was also recorded for R. solani and B. fuckeliana at 200 mL/L, with antifungal activity against B. fuckeliana maintained even at 100 mL/L. Additionally, Aloe vera extract at 300 mL/L was applied as a coating in the postharvest treatment of blueberries stored at 21 °C and 85% relative humidity. At the end of the experiment, the percentage of rotted berries was significantly lower in the treated group compared with the control. These findings suggest that Aloe vera gel is a promising postharvest treatment to extend shelf life and maintain blueberry quality and turgor during storage. |
