Abstract :After harvest, damages such as beery damage and bunch skeleton drying and fungal infections, especially Botrytis cinerea, limit the marketing of table grapes. SO2 is widely used to protect the quality of table grapes during the post-harvest storage. However, there is a risk of sulphite accumulation in grapes. For this reason, the use of organic products storage process is not allowed. Alternatives to SO2 have been tried to delay decay. In this study, the effects of Bacillus subtilis insert ignore into journalissuearticles values(Bs); QST 713 and Azotobacter chroococum + Azotobacter vinelandii insert ignore into journalissuearticles values(Ac + Av); preparations were tested in order to protect quality after harvesting in a variety of Vitis vinifera L. ‘Antep Karası’ Vitis vinifera L.); grape variety. Bs with 15 ml L-1, and 30 ml L-1, Ac + Av of 10 ml L-1, and 20 ml L-1 were applied before harvest insert ignore into journalissuearticles values(24 hours);. After harvest insert ignore into journalissuearticles values(2 hours); the product carried to cold storage insert ignore into journalissuearticles values(0 ± 1 °C, relative humidity 85%); it was put in 500 g sachets. The SO2 generator pad was used as a single dose with no application as control samples. Quality changes were followed in the samples taken by 15 days. In BS applications, weight loss insert ignore into journalissuearticles values(%ak); was below the application of Azotobacter and SO2 in the storage period. Bs 15 ml L-1 emerges positive effects on the ak, berry L value, maturity index insert ignore into journalissuearticles values(oi);; BS 30 ml L-1 emerges positive effects on the, ak, ° Brix, cluster skeleton of browning insert ignore into journalissuearticles values(sk);, determine the breaking strength insert ignore into journalissuearticles values(kd);, viewing and titratable acidity insert ignore into journalissuearticles values(TA); respectively. Bs and Ac + Av applications seem to be an alternative to SO2 applications in short-term such as 1 month of table grape storage.
