Effect of SO2 for controlling Botrytis cinerea in Italia and Red Globe grapes stored at different temperatures.

The main postharvest problem with table grapes is fungal decay caused by Botrytis cinerea. Among methods used to avoid it is the use of sulfur dioxide (SO2) generators at low temperature. As low temperatures are seldom used under Brazilian conditions, the effects of SO2 generators at different temperatures were studied. Two tests were carried out, the first with cv. Italia and the second with cv. Red Globe. A 3 x 2 factorial experiment in a completely randomized design was conducted, with three temperatures (4, 24 and 38 deg C) and two SO2 doses (with and without fast phase SO2 generators). At 0, 3 and 6 days the following parameters were analysed: berry colour, soluble solids content, pH, titratable acidity, stem colour, weight loss, decay index and SO2 residue in the fruit. The lowest temperature (4 deg C) was the best for preserving the quality of table grapes in both cultivars. High temperatures increased weight loss, stem colour, decay and SO2 residue. The use of SO2 reduced decay under the

 experimental conditions.
