RA storage of Jonagold

The eff ects of SmartFreshSM (1-Metylcyclopropene)
and storage temperature on fruit quality
were studied under regular air conditions. With
decreasing storage temperature as well as by a
SmartFreshSM treatment, the loss of fruit fi rmness
and acidity were reduced signifi cantly. Depending
on whether the fruits have been treated
with SmartFreshSM or not, any temperature
reduction of one Kelvin reduced the fruit fi rmness
loss by 0,35 kg cm-2 or 0,51 kg cm-2 in 100
days and increase potential storage time of
38 or 14 days. Thus, a storage temperature of
-0,5° C enable a storage time until end-December
even without SmartFreshSM treatment, assuming
5,5 kg cm-2 as a minimum fi rmness for
marketing. For SmartFreshSM treated fruits a
storage time almost until end of March is possible
if they were stored under the same storage
temperature.
