Abstract: SO2 injury threshold of four different varieties table grapes in Xinjiang province at different fumigation level were investigated. And the soluble solid content (SSC), rigidity, pH, SO2 accumulation in pericarp and sarcocarp were determined at the end of the shelf life. Results showed that SSC and rigidity were declined compared with the control. pH was not significantly changed. Results of continuous SO2 fumigation showed that the total sulfur was increased along with the storage time. But the excessively accumulation of sulfite was not appeared both in pericarp and sarcocarp.

Key words: table grapes, SO2 injury threshold, fresh keeping, accumulation
