Abstract

BUTTARELLI, M.S et al. Morphological characterization and evaluation of postharvest fungi of the ostiole of the fig variety “Guarinta”. FAVE. Secc. Cienc. agrar. [online]. 2022, vol.21, n.1, pp.21-30. ISSN 1666-7719.

The fig is a climacteric fruit with great perishability and short postharvest life. It has an ostiole that serves as a pollination medium and an entry site for fungal pathogens. In this work, three different protection strategies and their effect on the development of the ostiole were evaluated in addition to the presence of fungi. Fifteen white fig plants of the "Guarinta" variety were used. Images wereobtained by scanning electron microscope. The ostioli were evaluated in their structure and diameter. The presence of microorganisms was performed simultaneously. The mean diameter (mm) of pore in the control `C` was 7.64, in protection with mesh` M` it was 5.36 and protection with aluminum foil` PA`, 0.98; showing significant differences between the PA and C treatments. Figs wrapped with PA showed a higher incidence of pathogenic fungi. This constitutes a first approximation in the evaluation of types of protection.
