Abstract
Simulation models can make the determination of optimal storage conditions for new cultivars of Malus domestica less expensive and less time consuming.
On top of this, modeling creates the opportunity to apply batch dependent conditions.
Two experiments were set up to develop a model to describe ethylene production during the ripening and storage of Jonagold apples.
Fruit were harvested at different dates around the optimal harvest date to obtain different ethylene production rates at different ripeness stages.
Apples harvested at the three most extreme harvest dates were used for the storage experiment (CA conditions, 1% O2, 3% CO2) and either treated or not treated with SmartfreshTM, a commercially applied ethylene inhibitor.
The ethylene production rate was determined by gas chromatography and S-adenosyl-L-methionine (SAM) concentrations were measured with capillary electrophoresis.
During fruit ripening and during the storage of untreated fruit, an increase in ethylene production rate was noticed.
SAM concentrations on the other hand were not influenced significantly during the 4 weeks period around optimal harvest time.
