“…In this study, decrease in berry firmness was evident in grapes subjected to GA3 + CPPU + ABA treatment in both seasons. ABA application may negatively affect berries' firmness, a critical characteristic for the profitable postharvest handling of grapes for the fresh market because it affects shelf life and transportability (Batista et al 2015). ABA application is well known to cause decrease and loosening rigidity of the cell wall, leading to fruit softening and berries' cracking (Thomas et al 2008;Gambetta et al 2010).…”

The effect of gibberellic acid (GA3), forchlorfenuron (CPPU), and abscisic acid (ABA) on the parameters of yield of ‘Flame Seedless’ grapes was investigated. The clusters of 8-year-old grapevines were sprayed with solutions: GA3 at 25 mg·dm−3, CPPU at 10 mg·dm−3, and ABA at 300 mg·dm−3, alone or in combinations. GA3 and CPPU treatment increased yield, cluster weight and length, berry weight and diameter, as well as fruit firmness, but reduced the total soluble solids (TSS) and intensity of berry color. Anthocyanin content of berries treated with GA3 and CPPU increased significantly by ABA treatment. Shelf life was increased by GA3 and CPPU treatments, as they decreased the percentage of weight loss, shattering, and unmarketable berries after storing at 20 °C for 7 days. Thus, it can be concluded that the combined use of GA3, CPPU, and ABA may be an efficient practice for fruit enlargement, coloration, and keeping quality in ‘Flame Seedless’ grape.

“…In this study, the first four principal components had eigenvalues greater than 1, and thus, the data could be condensed into four factors, which explained 81% of the variance. In a study on genetic divergence among grapevine cultivars from the Active Germplasm Bank of Embrapa Semiárido, considering 11 fruit quality traits, it was found that two main components explained 79.45% of the total variance contained in the set of traits analyzed (Batista et al., 2015). At the same Germplasm Bank of Embrapa Semiárido, the genetic diversity and performance of grape cultivars were evaluated based on nine morphoagronomic traits (cycle duration, production, number of bunches, length, width and weight of the bunch, soluble solids content, titratable acidity, and ratio ) and four factors explained 84.12% of the variance (Leão et al., 2011).…”

The absence of seeds has been one of the most valued traits in grapes (Vitis spp.) for fresh consumption. However, the simultaneous selection of superior genotypes for multiple traits is complex. The objective of this study was to select genotypes of superior seedless table grapes in semiarid regions of Brazil. Multiple traits were considered by using the factor analysis and genotype–ideotype best linear unbiased prediction (FAI‐BLUP) selection index. A total of 110 grape progenies from 24 crosses were evaluated for traits of agronomic interest. Each hybrid was represented by a single vine plant, without experimental design or repetition. The mixed‐model methodology was used to predict the breeding values. The FAI‐BLUP index was used to select superior genotypes based on factor analysis and the genotype–ideotype distance. Four factors explained the 11 characteristics studied, with a variability of 81.84%. Desirable gains were observed for 10 of the 11 traits evaluated. The FAI‐BLUP index allowed the selection of superior seedless table grape hybrids, which can be used in the genetic improvement of grapevines. In conclusion, we report the selection of seedless table grape hybrids for our study to advance in the table grape breeding program in Brazilian semiarid regions.

Exogenous Abscisic Acid Promotes Anthocyanin Biosynthesis and Increased Expression of Flavonoid Synthesis Genes in Vitis vinifera × Vitis labrusca Table Grapes in a Subtropical Region

et al. 2018

Hybrid (Vitis vinifera ×Vitis labrusca) table grape cultivars grown in the subtropics often fail to accumulate sufficient anthocyanins to achieve good uniform berry color. Growers of V. vinifera table grapes in temperate regions generally use ethephon and, more recently, (S)-cis-abscisic acid (S-ABA) to overcome this problem. The objective of this study was to determine if S-ABA applications at different timings and concentrations have an effect on anthocyanin regulatory and biosynthetic genes, pigment accumulation, and berry color of the Selection 21 cultivar, a new V. vinifera ×V. labrusca hybrid seedless grape that presents lack of red color when grown in subtropical areas. Applications of S-ABA 400 mg/L resulted in a higher accumulation of total anthocyanins and of the individual anthocyaninsanthocyanins: delphinidin-3-glucoside, cyanidin-3-glucoside, peonidin-3-glucoside, and malvidin-3-glucoside in the berry skin and improved the color attributes of the berries. Treatment with two applications at 7 days after véraison (DAV) and 21 DAV of S-ABA 400 mg/L resulted in a higher accumulation of total anthocyanins in the skin of berries and increased the gene expression of CHI, F3H, DFR, and UFGT and of the VvMYBA1 and VvMYBA2 transcription factors in the seedless grape cultivar.
