Effect of various post harvest treatments on percentage of shrinkage and spoilage of tomato (Lycopersicon esculentum Mill)

The experiment was conducted in the laboratory of the Department of CIHAB, PSB (Institute of Agriculture), Visva-Bharati, Sriniketan (WB). The experiment was laid out in RBD with nine treatments each comprising of three replications and ten fruits per replication. The results indicated that ripening was initially delayed by MAP, NAA and NAA+MAP treatments. Fruits treated with NAA+MAP, NAA+PMAP and GA3+MAP showed minimum percentage of shrink age up to 16th day of storage. The shrinkage was significantly delayed by MAP and PMAP treatments at the beginning. Relatively less percentage of rotting was noted in PMAP and in combination of PMAP and GA3 treatments. It is evident from the results that the fruits under NAA, GA3 and PMAP exhibited promising results in extending the storage life of tomato at room temperature up to two weeks.
