“…Regarding the berry color attributes, clusters that received S-ABA application, particularly those that were treated with two applications, independent of the concentration, had the lowest L* (lightness) ( Table 2), which indicates that 'Isabel' grape berries subjected to these treatments showed a darker skin color. Similar results were observed in 'Red Globe', 'Flame Seedless', 'Crimson Seedless', and 'Hongisul' table grapes (Peppi et al, 2007Shin and Park, 2012).…”

Vitis labrusca grapes are widely cultivated in some countries such as Brazil and the United States, especially for juice production. ‘Isabel’ is one of the main cultivars because of its high production and disease tolerance, but the juice is deficient in color. The objective of this study was to evaluate the effect of timing and concentration of (S)-cis-abscisic acid (S-ABA), a specific isomer of abscisic acid applied to ‘Isabel’ grapes, aiming to increase anthocyanin accumulation and to improve juice quality. The trial was conducted on two consecutive seasons (2011 and 2012) in a commercial vineyard located in Maringa, PR, Brazil. The vines were trained in an overhead trellis system and spaced at 4.0 × 1.0 m. The statistical model used was a randomized block design with four replications and five treatments: control; S-ABA at 200 mg·L−1 at 7 days after veraison (DAV); S-ABA at 400 mg·L−1 at 7 DAV; S-ABA at 200 mg·L−1 at 7 DAV + 200 mg·L−1 at 15 days after the first application (DAFA); and S-ABA at 400 mg·L−1 at 7 DAV + 400 mg·L−1 at 15 DAFA. There were no significant differences between treatments in relation to berry or cluster size or weight. S-ABA application resulted in increased anthocyanin concentrations in both berries and juices, mainly when 400 mg·L−1 was applied. Sensory analysis also revealed the efficiency of this plant growth regulator to promote better acceptance of grape juices. Thus, a single application of S-ABA at 400 mg·L−1 at 7 DAV is sufficient to increase the anthocyanins concentration of ‘Isabel’ grapes, improving the acceptance of juice by consumers.

“…The application of S-ABA also increased the anthocyanin concentration in other cultivars, especially on table grapes such as 'Flame Seedless' , Red Globe' (Peppi et al, 2007), 'Alachua' and 'Noble' (Sandhu et al, 2011), and 'Hongisul' (Shin and Park, 2012).…”

“…NIRS is a fast, accurate, and green technology to identify unknown samples based on the relationship between the near-infrared spectra of a substance and its molecular properties (Santos et al, 2015). The fruit quality has been traditionally evaluated on the basis of a number of external attributes such as shape, color, scars, and size (Shin & Park, 2012). In recent years, some internal parameters including sugar content, acidity, and crispness have become increasingly important for fruit quality evaluation (Costa et al, 2006).…”

Harvested plums can be stored at low temperatures for a long time. During storage, several quality attributes of plums undergo changes, which are also associated with their best-before date. This research proposed a fast method for the quick determination of plum storage time. With the integration of near-infrared spectra measurements, plum quality parameters (firmness, soluble solids content, pH, and color), several classification models have been developed to determine the storage time. A variety of methods such as linear discriminant analysis (LDA), partial least squares (PLS), support vector machine (SVM), and generalized linear models (GLM) were used.It is concluded that the models based on near-infrared spectra only with 14 selected features using LDA and PLS provide the best estimations, with accuracy values of 0.9917 and 0.9854, respectively. The models built with the attributes provide favorable results when using LDA and SVM (Radial basis), with accuracy values of 0.9261 and 0.8734, respectively.Novelty impact statement: For the first time, we proposed the use of non-destructive NIRS to establish classification models in plums based on post-harvest storage time for maturity prediction. At the same time, several fruit quality attributes were also used for comparison.

The purpose of this study is to suggest indicators and proper standards to forecast the sensory quality of 'Hongisul' grape. Further, this study determines the optimum fruit load of 'Hongisul' grape reflecting consumer preference. Among several quality attributes, identified through instrumental and sensory evaluation, soluble solid-acid ratio was the most useful indicator of consumer preference for 'Hongisul' grapes. The ideal soluble solid-acid ratio for marketable grapes was found to be higher than 86.3. Analysis on the effects of fruit load control on fruit quality revealed a negative correlation where the latter increased as the former decreased. This trend is common for all grape species. The field with a fruit load of 1,400 kg･10 a -1 exhibited a soluble solid-acid ratio of less than 86.3, uneven coloring and slow softening texture at the mature stage. However, fruit quality proved excellent in the field with a fruit load of 1,200 kg･10 a -1 or less. It is therefore proposed that fruit load should be controlled to 1,200 kg･10 a -1 or less when growing 'Hongisul' grapes to produce high quality grapes. We believe that this result can be used as a standard in judging harvest time and evaluating fruit quality.
