This article examines the effect of ethylene gas on the external and internal properties of apple fruits during storage, in particular, on their degree of hardness. The main purpose of the study is to evaluate the effect of ethylene on biochemical and physiological changes in fruit tissues and, as a result, to determine changes in the shelf life, appearance and consumer properties of apple fruits.the notation. The article examines the effect of ethylene gas on the external and internal properties of apple fruits during storage, in particular, on their degree of hardness. The main purpose of the study is to evaluate the effect of ethylene on biochemical and physiological changes in fruit tissues and, as a result, to determine changes in the shelf life, appearance and consumer properties of apple fruits.  Data on the possibility of preserving the quality of apples for a longer period of time through the use of ethylene sorbents in fruit storage and reducing the ethylene content are presented.

Storage of apple fruits, degree of hardness, gas content of ethylene, local methods, appearance, physiological condition of fruits.
