Abstract
This paper studied the effects of sodium diacetate (SDA) treatment on the decay of grapes caused by Botrytis cinerea and on postharvest preservation during storage, The results show that more than 3 g/L of SDA could completely inhibit the growth of B. cinerea in vitro. Grapes treated with 5 g/L SDA significantly improved the activities of antioxidant enzymes and upregulated the expression level of PR gene families . SDA treatments significantly reduced the rotting rate and maintained good quality of grapes in storage. The results are of significance to reveal the induction mechanism of SDA on disease resistance of grapes.
