Popis:	Antonovka apples, yellow and green, which were picked on August 25 and September 1 have been analyzed. The reflection coefficients of the apple surface were measured at wavelengths of 700 and 750 nm. R750 / R700 ratio was used to estimate the chlorophyll content in the skin. It is shown that the reflection coefficients decrease in storage with time. It is proved by the change in the structure of the apple tissue; the light is absorbed to a greater extent by it. The change in the content of chlorophyll in the skins of apples remains at the same level during the storage. There are some fluctuations in its content. It has been shown that fruit diversity increases with the storage time.
