Effects of sulfur dioxide on postharvest quality and quantity of table grapes cvs. "Keshmeshi seedless" and "Shahroudy" in cold storage.

The effects of 4 levels of SO2 (0.0%, 0.06%, 0.125% and 0.25%) on the qualitative and quantitative characteristics of 2 Persian grape cultivars, Keshmeshi seedless and Shahroudy, were evaluated during cold storage in 1995-97. The effect of SO2 on decay was significant at 1%, and maximum control was obtained at 0.25%. No significant difference was observed for 0.125% SO2. Increasing SO2 concentration resulted in increased quantity and intensity of bleaching of the berries. A linear relationship was observed between bleaching and SO2 concentration, with that the highest bleaching occurring at 0.25%. Increased storage periods also increased bleaching. The effects of SO2 on weight loss, shattering, and rachis colour were also significant; rachis colour and berry shattering were both decreased.
