Composite effects of gibberellic acid and kinetin on the postharvest-life of Solanum melongena L. [electronic resource]

Includes bibliographic reference

To reduce the qualitative loss and prolong the shelf-life of brinjal (Solanum melongena L), the application of an exogenous coating
of gibberellic acid and kinetin separately and also multiple combinations of GA and KN (10 ?M plus 10 ?M, 20 ?M plus 20 ?M, and
30 ?M plus 30 ?M) were tested for a storage period of 14 days. The uncoated brinjal could sustain about 7 days and deteriorate
early whereas the coated brinjal now has a successful storage period of 14 days. During the storage, it was observed a gradual
decrement in titratable acidity, protein content, catalase, and peroxidase activity; whereas a gradual increment in proline content
and DPPH radical scavenging activity. Among these three combinations, the combination of 10 ?M GA plus 10 ?M KN preserved the qualitative
attributes and was effective in delaying the senescence process. The mathematical model and principal component analysis also justified
the results of the present study. This study influences a better method to meet market and customer expectations for volume, quality,
and other product and transaction attributes like nutrition, food security, and product safety.
