The experiments were performed with Antonovka
obyknovennaya fruit during the period of ripening
prior to harvest. The fruit placed in storage were taken
from different harvests and varied in the content of
chlorophyll. The content of chlorophyll in the apple
skin was measured using the ratio of reflectance at
R750/R700 [2]. Apples (15 kg) were picked and placed in
a box. The fruit in storage were subjected to the cyclic
effect of heat and light to imitate a natural orchard
environment. For this purpose, apples were stored in
15–25°C air during the daytime and put in a refriger
ator (3–4°C) at night. After 4–5 months of storage,
the fruit were analyzed for scald.
