RESULTS AND DISCUSSION
The year 2009 was marked by favorable weather
conditions: deviation in the sum of active tempera
tures from its long term average for the first decade of
September was 123°C; precipitation from the middle
of April to September 10 amounted to 254 mm; hydro
thermal index equaled 1.03. The content of chloro
phylls in the apple skin was measured from August 28
to September 21 using the ratio of reflectance at
R750/R700. It can be seen from Fig. 1 that the content
of chlorophylls in the apple skin was minimum on
August 31, September 11, and September 21. It
reached maximum values during September 4–9.
Heat and light treatment was applied to the fruit har
vested on the days as shown in Fig. 2. Simultaneously,
