Descripción

Biocontrol became an alternative to control of postharvest decay of table grape, however due to the minimal handling in the packing-house its application is limited to field. Therefore, considering the semi-arid climate of the region of the São Francisco River Valley (Brazil), tolerance to climate must be included in the selection process of biocontrol agents. In this work the yeast isolates L7K and L10, which were previously selected for control of postharvest decay of grapes, were evaluated for their natural tolerance to UV-B light, temperature and low water availability.
