Application of Abscisic Acid (S-ABA) to ‘Crimson Seedless’ Grape Berries in a Mediterranean Climate: Effects on Color, Chemical Characteristics, Metabolic Profile, and S-ABA Concentration

Color of berry and juice of 'Isabel' grape treated with abscisic acid in different ripening stages

“…However, timing of application can vary according to the cultivar and growing region (Peppi et al, 2007a(Peppi et al, , 2007bFerrara et al, 2013). As noted for anthocyanin concentration, independently of application timing, there was an improvement in the color of 'Isabel' grape berries treated with S-ABA (Table 3), showing the relationship between the results obtained for these variables.…”

On the use of Ethephon as abscising agent in cv. Crimson Seedless table grape production: Combination of Fruit Detachment Force, Fruit Drop and metabolomics

“…In the region 2.5-0.0 ppm most signals derive from amino acids. Signals attribution was made by comparison with spectra of authentic samples and with literature data (Ali et al, 2011;Ferrara et al, 2013Gallo et al, 2014;Son et al, 2009). In Table 2, metabolites identified in berries of 'Crimson Seedless' are listed and, for each signal, chemical shift (d, ppm) and multiplicity are also reported.…”

“…Metabolomics aims at measuring the global, dynamic metabolic response of the living systems to biological stimuli and provides information on a wide range of detectable chemical compounds contained in food products. Metabolomic studies usually involve Nuclear Magnetic Resonance (NMR) spectroscopy or High Resolution Mass Spectrometry (HRMS) supported by multivariate statistical methods (Ali et al, 2011;Bevilacqua et al, 2012;Ferrara, Mazzeo, & Netti et al, 2014;Ferrara et al, 2013;Gallo et al, 2014;Kim, Choi, & Verpoorte, 2010;Nicholson & Lindon, 2008;Schripsema, 2010;Son et al, 2009;Sumner, Mendes, & Dixon, 2003;Wishart, 2008). It is generally accepted that a single analytical technique seldom provides complete information on the metabolome and therefore a combined approach is desirable to gain a comprehensive view.…”

“…The positive effect of S-ABA on skin color of cv. Crimson Seedless was ascertained, without any significant change in the profile of the primary metabolites (Ferrara et al, 2013). Moreover, the effects of gibberellic acid (GA 3 ) and 1-(2-chloropyridin-4-yl)-3-phenylurea (forchlorfenuron, CPPU) on amino acids composition of cv.…”

The table grape ‘Victoria’ with a long shaped berry: a potential mutation with attractive characteristics for consumers

“…L* refers to the lightness of a colour, from black = 0, to white = 100; C* refers to the intensity of a colour, with 0 being achromatic, and h ° is the position on the colour wheel where 0° = red, 90° = yellow, 180° = green, and 270° = blue. Berry firmness was measured with a 2‐mm needle digital penetrometer (FM200; PCE Italia s.r.l., Capannori, Italy) in accordance with previously described procedures . A hand‐held, temperature compensating digital refractometer (Hanna Instruments, Padova, Italy) and an automatic titrator (PH‐Burette 24; Crison Instruments, Barcelona, Spain) were used for the following determinations: (1) total soluble solids content (TSS), (2) pH, (3) titratable acidity (TA) (as g tartaric acid L −1 juice at pH 8.1).…”
