20.500.12556/RUL-136892 Effect of spring frost damage on apple fruit (Malus domestica Borkh.) inner quality at harvest In the last few years, spring frosts have become more of a rule than an exception. There are several prevention measures available for growers and numerous are being tested; however, fruitlets are often affected to some extent. One of the more common phenomena is the development of frost rings. The aim of our study was to evaluate how the occurrence of frost rings affects sugar, organic acid, and phenol content in the flesh and phenol content in the peel of cv. ‘Gala’ apples. The results show that the frost damage from spring frost affects compounds in the peel, as well as in the flesh of ripe apples. The flesh of fruits with frost rings contained higher content of fructose and in the flesh directly under the rings there was higher sorbitol and malic acid content. Additionally, the hydroxycinnamic acid and dihydrochalcone content in apple flesh was also altered by frost. The frost-affected peel had a completely different ratio of phenolic compounds content in comparison to healthy apples. While there was a significantly higher content of hydroxycinnamic acids and dihydrochalcones in the corky peel in comparison to the unaffected peel, the flavonol and anthocyanin content was considerably lower. frost rings sugar sorbitol phenolic content kmetijstvo sadjarstvo jabolka pozeba kakovost plodov true false true Angleški jezik Slovenski jezik Članek v reviji 2022-05-24 08:48:25 2022-05-24 08:48:26 2022-09-15 04:14:23 0000-00-00 00:00:00 2022 0 0 10 str. iss. 1, art. 14 Vol. 12 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 634.11/.12 2077-0472 10.3390/agriculture12010014 90849283 agriculture-12-00014-v2.pdf agriculture-12-00014-v2.pdf 1 B6716C1A26628BD745520D6BFF82293E af963d0cf92bf93204c4f4b13965ec2a7724d07717db5218cddb01dad96317fb eb4b6718-db2d-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=156690 https://www.mdpi.com/2077-0472/12/1/14 1 62818531-db2d-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=156689 Biotehniška fakulteta 0 0 0
