fruits (Solovchenko and Schmitz-Eiberger, 2003). In the same study
of Solovchenko and Schmitz-Eiberger (2003), Fo was unchanged

respectively, while it was increased in the shaded fruits of
both cultivars. The increased sensitivity of apple peel to UV-B in
that particular study may relate to the use of fruit that were stored
for 3 months at low temperature and in controlled atmosphere
