Abstract

The objective of this study will be evaluate essential oils in postharvest control of anthracnose in mangoes 'Palmer'. For treatments, will be used three essential oils with antifungal activity from plants. Initially will be evaluated the antifungal potential of the ten essential oils obtained by the method of assessing the minimum inhibitory concentration. After this selection will be tested in vitro the three best essential oils with five different concentrations of each product. At this stage the products will be added to the culture medium, poured into a petri dish in which is placed the fungus. It will be used six replicates per treatment. In step three will be performed in vivo experiments where mango 'Palmer' will be immersed for 1 minute in three concentrations of each essential oil associated with commercial wax. After drying and formation of the coatings, the fruits will be stored at 12 º C and 80 ± 5% RH for 14 days, and for a further 4 days at 25 ° C to simulate marketing. In vitro experiments will be evaluated mycelial growth and conidial germination, and in vivo experiments fresh mass, peel color and pulp firmness, respiration rate and ethylene production, titratable acidity, soluble solids, rot incidence, polyphenols extractable total, total carotenoids, peroxidase, polyphenoloxidase and phenylalanine ammonia-lyase activity enzymatic. The results will be submitted to analysis of variance and treatment effect, when significant, will be matched by Test F. Significant differences being the results will be compared using minimum significant difference (SMD) with 95% confidence interval (P d .05).
