Abstract
The storability of apricot fruits was examined after foliar application of Ca-nutrients and postharvest treatments, i.e. modified atmosphere packaging and application of 1-methylcyclopropene.
The experiment was carried out in 2017 on the apricot cultivar ‘Buda’. Foliar application of 0.1% of Calcium (Wuxal®Calcium) was done in stages when apricot fruits reached a diameter of 11, 21, and 30 mm.
Postharvest treatment included: modified atmosphere packaging and 1-methylcyclopropene.
The fruit firmness, chemical composition, and color were analyzed at harvest and following 15 days of cold storage.
Apricots treated with Ca and stored in modified atmosphere packaging conditions retained a higher degree of hardness following the storage versus the control and fruits treated with 1-methylcyclopropene, respectively.
Apricot color changed due to the storage and different postharvest treatments, but not as a consequence of Ca application.
The highest change in color was present in fruits treated with 1-methylcyclopropene after cold storage.
At harvest, Ca-treated apricots showed a lower titrable acidity when compared to the untreated fruits, while regarding total soluble solids no significant difference was recorded among the fruits.
On the other side, following cold storage Ca-treated apricots were characterized by significantly higher total soluble solids.
Carotenoid content was influenced by packaging, while in the case of phenols, this effect was achieved by storage and a combination of storage and Ca treatment.
Based on the obtained results, it can be assumed that, if apricots are planned for storage and transport, a combination of foliar Ca treatment and modified atmosphere packaging can be recommended.
