| ABSTRACT The aim of this study was to evaluate the effects of ethanol on the control of Colletotrichum spp. in ‘Kumagai’ guava and on the fruit physical-chemical attributes. For this purpose, three assays were carried out. For the first assay, fruit were exposed to ethanol vapor (0, 1, 2, 4, and 8 mL∙kg-1), applied in hermetic containers. On the second, ethanol was applied by immersion for 2 minutes in different concentrations (20, 30, 40, and 50%). On the last assay, fruit were immersed in 30, 40, and 50% ethanol for 2, 5, and 10 minutes. Fruit that were not exposed to volatile (first assay) or water treated (second and third assay) were used as control. In all assays, guavas were first inoculated with a conidial suspension of Colletotrichum spp. and... |

| ABSTRACT Methyl jasmonate (MJ) is an endogenous regulator that can influence fruit ripening and the defense system against pathogens. This work verified the influence of this regulator on postharvest physiology, control of anthracnose and physicalchemical attributes of ‘Kumagai’ guava (Psidium guajava L.). Guavas harvested at mature-green and ripe stages were treated with 0, 1 and 10 μmol∙L−1 MJ as gas in hermetic containers (200 L) with air circulation for 24 h. Fruit were inoculated with Colletotrichum gloeosporioides spore suspension (105 spores∙mL−1) 24 and 48 h after treatment. During ripening, at 25 °C and 80 – 90% of relative humidity, respiration, ethylene production, anthracnose incidence, severity and quality of guavas were assayed. Data were... |
