This
concentration of ethylene was chosen to simulate
concentrations encountered in commercial marketing
of strawberries (Wills and Kim, 1995). Two
control treatments were included in each experiment
comprising an untreated unit and a unit held
in a nitrogen atmosphere. The quality of strawberries
was assessed daily for fruit held at 20°C
and every second day at 5°C. At each examination
berries with mould growth, rotting, softening
or colour change were removed and the percent of
berries in an acceptable condition was calculated.
