Abstract
The article presents the research results of the effect of post-harvest treatment with Phytomag preparation of fruits of 21 apple tree varieties of domestic and foreign breeding on their storability and quality. The purpose of the research is to determine the effectiveness of the combined effect of such technological techniques as post-harvest fruit treatment with Phytomag preparation and their storage in conventional (CGD) and regulated (RGD) gas dynamics on the formation of quality and storability of apples grown in the Crimea. The data obtained showed that the treatment of fruits with an ethylene inhibitor Phytomag during storage in conventional and regulated gas dynamics reduces losses, depending on the variety, by 1.5-1.8 times. It is established that the processed fruits retain their original marketable appearance, have high quality components during the entire storage period and after opening the refrigerating chambers, selling the fruits and bringing them to the consumer. It is proved that in the conditions of the Crimea such varieties as Tavria, Krymskoye Zimnee, Krymskoye, Orion, Kimmeria, Brebern, Fuji, Idared, Pink Lady can be successfully stored in a conventional gas dynamic with post-harvest treatment with preparation inhibiting ethylene synthesis. The advantage of storage in regulated gas dynamic was shown by the varieties Aromat Kryma, Predgornoye, Golden Delicious, Crispin, Granny Smith, Glouster, Gala, Jonagold.
Highlights
The strategic goal of any state is to ensure food security
The results of the performed studies indicate that after storage of apples, both in the cooled gas dynamic (CGD) and in the RGD, the experimental samples with Phytomag preparation treatment had higher pulp density indicators compared to the control ones (Table 1)
The data obtained confirm the high efficiency of post-harvest treatment of the fruits of the studied apple tree varieties with an ethylene inhibitor Phytomag in combination with storage in conventional and regulated gas dynamics, providing a 1.5-1.8-fold reduction in losses
Summary
Apples are in great demand due to their taste qualities They are classified as valuable food products having nutritious, and medicinal properties [4,5]. With the selection of apple tree varieties and the proper organization of storage, it is possible to provide the population and vacationers of the peninsula with fresh fruits throughout the year. The breeders of the Crimean Experimental Horticulture Station have created apple tree varieties that have significant adaptive potential to the rather difficult soil and climatic conditions of the Crimean Peninsula. They are distinguished by high fruit productivity and marketability. Most of the varieties belong to the winter group and are suitable for long-term storage
