Applied approach for preservation and prolonged storage periods of Thomposn seedless grapevines [electronic resource].

Includes references.

The aim of the present study is to determine the losses from postharvest wastage of Thompson seedless grape. Possibilities to control these wastages by safe methods such as fumigation by vaporus acetic acid, and chitosan coated. Moreover, screening new bio-agents isolated from surface of fruits and testing them in cold storage against the most important postharvest decay of grape was also investigated. The main causal organisms of postharvest fruit rots of Thompson grape were Botrytis cinerea and Pencilllum expensum during storage periods in two seasons. Fumigation treatments with acetic acid vapour 30 pilL. reduced the total wastage to 6.11 and 7.45% in two seasons respectively, as compared with 31.57 and 35.70% for control after 30 days of storage at (fC. It could be suggested that acetic acid vapours might be safely used commercially as a new approach for prolongate of storage periods of grapes.
