The influence of harvest date and storage conditions on fruit firmness.

’Red Jonaprince’. Season 2018/2019

Conclusions

Analyses performed after storage confirmed the beneficial effects of low

oxygen technology and post-harvest 1-MCP treatment on fruit firmness

and acidity, for both cultivars.

Post-harvest treatment with 1-MCP and use of low oxygen technology

reduced the rate of ethylene production, regardless of the season,

harvest date and storage temperature. The impact of low oxygen storage

and 1-MCP treatment on ethylene pathway was also expressed in the

decrease of ACC oxidase activity.

In case of ‘Red Jonaprince’ apples, only fruits treated with 1-MCP and

stored in CA conditions were characterized by satisfactory firmness after

storage. For untreated fruits, even those stored in DCA, a very strong

decline of firmness during shelf life was noticed. Such a feature of the

fruit firmness could be related to a very hot summer in the year 2018.
