Response of Various Postharvest Treatments on TSS and Acidity Content of Tomato (Lycopersicon esculentum Mill)

An investigation was undertaken in the Laboratory of the Department of Crop Improvement, Horticulture and Agricultural Botany, Palli Siksha Bhavana (Institute of Agriculture), Visva-Bharati, Sriniketan (West Bengal) to study the efficacy of NAA, GA₃ and packaging materials alone and in combination with TSS and acidity content of tomato (Lycopersicon esculentum Mill). The results of the experiment revealed that there was significant change in TSS content of tomato during storage period. The lowest and highest TSS value recorded is 5.97° and 7.73° Brix, in treatments of GA₃ 50 ppm + MAP and control, respectively. Similarly when the total acidity content of tomato is concerned, it declined shortly from 18^th day of storage in all most all treatments and control. Maximum 1.28% acid was recorded on GA₃ + MAP at 6^th day of storage. Regarding TSS acidity ratio there was increase in the values in almost all the treatments along with the control at the last part of the storage period.
