Abstract:
Four varieties of mango namely Dashahari, Langra, Chausa and Safeda had been taken for the experiment. At maturity condition, mango fruits were harvested and stored in cardboard carton by post harvest application of salicylic acid at 0.1, 0.5 and 1.0 g/l doses. The analysis of pectin methyl esterase, cellulase, polyphenol oxidase, peroxidase, total chlorophyll and beta carotene were done at five days intervals after storage. Highest pectin methyl esterase enzyme activity (0.91 units/g) was reported in variety Dashahari at five days ambient storage period by 1.0 g/l salicylic acid application. Maximum cellulase and polyphenol oxidase enzyme activity (12.84 and 56.38 units/g) was reported in the variety Dashahari at five days ambient storage period by 0.1 g/l salicylic acid application. Highest peroxidase enzyme activity (463.69 units/g) was reported in variety Dashahari at 20 days ambient storage period after the application of 0.5 g/l salicylic acid treatment. Maximum total chlorophyll content (39.86 mg/g) was reported in the variety Dashahari at five days storage by 1.0 g/l salicylic acid application. Highest beta carotene content (3495.93 μg/100g) was reported in the variety Dashahari at 20 days ambient storage period by 0.5 g/l salicylic acid treatment. The present study indicated that after salicylic acid application pectin methyl esterase, cellulase, polyphenol oxidase and chlorophyll content decreased but the peroxidase and beta carotene content increased during storage in cardboard carton
