At harvest, plum quality parameters, such as weight, total phenolics (including anthocyanins, in BS), total carotenoids, and antioxidant activity, in both hydrophilic and lipophilic compounds were found at higher levels in plums from SA-, ASA-, and MeSA-treated trees than in those from control trees. During storage, fruit firmness, total acidity, and antioxidant compounds were at higher levels in treated, than in control, plums, which show an effect of salicylate treatments on delaying the plum postharvest ripening process. In addition, the activity of the antioxidant enzymes catalase (CAT), peroxidase (POX), superoxide dismutase (SOD), and ascorbate peroxidase (APX) were also enhanced at the time of harvest in salicylate-treated plums as compared with plums from control trees. The activity of these antioxidant enzymes was also found at higher levels in salicylate-treated plums during storage. Thus, preharvest treatment with salicylates could be a safe, eco-friendly, and new tool to improve and maintain plum quality attributes, and especially their content of antioxidant compounds, with an additional effect on delaying the postharvest ripening process through increasing the levels of antioxidant compounds and the activity of the antioxidant enzymes.<\/jats:p>","DOI":"10.3390\/ijms18091911","type":"journal-article","created":{"date-parts":[[2017,9,6]],"date-time":"2017-09-06T11:23:34Z","timestamp":1504697014000},"page":"1911","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":37,"title":["Enhancement of Antioxidant Systems and Storability of Two Plum Cultivars by Preharvest Treatments with Salicylates"],"prefix":"10.3390","volume":"18","author":[{"given":"Alejandra","family":"Mart\u00ednez-Espl\u00e1","sequence":"first","affiliation":[{"name":"Department of Agro-Food Technology, University Miguel Hern\u00e1ndez, 03312 Orihuela, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mar\u00eda","family":"Serrano","sequence":"additional","affiliation":[{"name":"Department of Applied Biology, University Miguel Hern\u00e1ndez, 03312 Orihuela, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Valero","sequence":"additional","affiliation":[{"name":"Department of Agro-Food Technology, University Miguel Hern\u00e1ndez, 03312 Orihuela, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6496-1802","authenticated-orcid":false,"given":"Domingo","family":"Mart\u00ednez-Romero","sequence":"additional","affiliation":[{"name":"Department of Agro-Food Technology, University Miguel Hern\u00e1ndez, 03312 Orihuela, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Salvador","family":"Castillo","sequence":"additional","affiliation":[{"name":"Department of Agro-Food Technology, University Miguel Hern\u00e1ndez, 03312 Orihuela, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8715-8278","authenticated-orcid":false,"given":"Pedro","family":"Zapata","sequence":"additional","affiliation":[{"name":"Department of Agro-Food Technology, University Miguel Hern\u00e1ndez, 03312 Orihuela, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2017,9,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"373","DOI":"10.1146\/annurev.arplant.55.031903.141701","article-title":"Reactive oxygen species: Metabolism, oxidative stress, and signal transduction","volume":"55","author":"Apel","year":"2004","journal-title":"Ann.
