“…One of the most interesting practices might be the application of chemical elicitors such as methyl jasmonate (Fernández‐Marín, Puertas, Guerrero, García‐Parrilla, & Cantos‐Villar, 2014; Portu, López, Baroja, Santamaría, & Garde‐Cerdán, 2016; Portu, Santamaría, López‐Alfaro, López, & Garde‐Cerdán, 2015; Rohwer, & Erwin, 2008) or benzothiadiazole (Gómez‐Plaza, Bautista‐Ortín, Ruiz‐García, Fernández‐Fernández, & Gil‐Muñoz, 2017; Ruiz‐García et al., 2012; Ruiz‐García et al., 2013), substances that are able to stimulate defense responses in plants, and that might activate the phenylpropanoid pathway. Plant growth regulators such as abscisic acid (Ferrandino, & Lovisolo, 2014; Roberto et al., 2012; Ruiz‐García et al., 2013; Yamamoto et al., 2015) or ethylene involved in several physiological processes have also been proposed to increase the polyphenolic content in grapes (Böttcher, Harvey, Boss, & Davies, 2013; Human, & Bindon, 2008; Leão, Lima, Costa, & Gomes da Trindade, 2015).…”
