20.500.12556/RUL-136229 Salicylate treatment affects fruit quality and also alters the composition of metabolites in strawberries This study evaluated the effect of preharvest treatments with salicylates (salicylic acid (SA), methyl salicylic acid (MeSA) and acetyl salicylic acid (ASA)) on fruit quality parameters and primary and secondary metabolites during ripening at five sampling dates. The results showed that salicylates affect overall fruit quality, and some very desirable and important properties of strawberry fruits were acquired by the treatments, such as a deeper red colour (decreased hue angle), delayed ripening process with maintenance of higher fruit firmness, and higher sugar and ascorbic acid content. HPLC-MS analysis of the phenolic contents showed at almost all sampling dates that treatment with salicylates increased the content of some phenolic groups, the contents of the hydroxycinnamic acids (SA: up to 18%; MeSA: up to 13% increase), flavanols (SA: up to 27%, MeSA: up to 36% and ASA: up to 24% increase), anthocyanins (SA: up to 51%, MeSA: up to 33% and ASA: up to 28% increase) and also flavonol glycosides such as flavones. Total phenolics in fruits also increased-up to 27% with SA and up to 28% with MeSA. In general, better fruit quality and higher metabolite content were obtained with SA. salicylic acid (SA) methyl salicylic acid (MeSA) acetylsalicylic acid (ASA) sugars organic acids phenolic compounds bioactive compounds jagode salicilna kislina kemična sestava sekundarni metaboliti fenolne spojine organske kisline bioaktivne snovi true false true Angleški jezik Slovenski jezik Članek v reviji 2022-04-20 14:37:48 2022-04-20 14:37:49 2022-09-15 04:13:36 0000-00-00 00:00:00 2021 0 0 16 str. iss. 10, art. 400 Vol. 7 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 635 2311-7524 10.3390/horticulturae7100400 82092803 horticulturae-07-00400-v2.pdf horticulturae-07-00400-v2.pdf 1 60911AF3E33D224AD613CCEEA2C918DD 2c6c84be1742636135a6de7bcce508e6fe9832da3a360a1aa7d7d92f4986ef6a d03d26c2-c0a6-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=155766 https://www.mdpi.com/2311-7524/7/10/400 1 a0282def-c0a6-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=155765 Biotehniška fakulteta 0 0 0
