Abstract

In 2019–2020 in the RUE “Institute of Fruit-growing” research was carried out to study the effect of the modified gas
 environment (MGE) on the preservation of quality and consumption period extension of the fresh apple-tree fruits of early
 ripening period.
 The objects of research were the fruits of seven apple-tree species of early ripening period (Aksamit, Kovalenkovskoe,
 Mechta, Palanez, Papirovka, Ranak, Slava pobeditelyam), grown in the department of selection of fruit crops of the
 RUE “Institute of Fruit-growing”.
 The change of the gas composition in a closed package makes it possible to reduce the natural weight loss for species
 by 2.9 % average and to increase the output of healthy fruits in all species.
 The use of MGE minimizes losses from physiological disorders in the apple-tree fruits of early ripening period by 1.7–2.5
 times and reduces losses from fungal diseases by 2.0–7.3 %, depending on the species.
 Storage in MGE increases the safety of the fruits after removal from storage (residual effect) by 3–6 days, depending on
 the species.
