Characterization of maturity and quality of Brazilian apirenic grapes in the São Francisco river Valley

Abstract

The objective of this study was to characterize and correlate maturity and quality of the first varieties of Brazilian seedless grapes 'BRS Clara', 'BRS Linda', 'BRS Morena', and 'Advanced Selection 8' compared with the American variety 'Crimson Seedless' in compliance with the Brazilian Normative/2002 and export standards Advanced Selection 8' is dark reddish, has large clusters, and is a very large ellipsoid berry; 'BRS Morena' is black with medium sized clusters and large berry shaped as ellipsoid to globoid; 'BRS Linda' is light green and has large sized clusters; 'Crimson' is pink and has small clusters with berries varying from medium to large sizes and ellipsoid shaped; and 'BRS Clara' is green yellowish has medium sized clusters and small berry of elongated ellipsoid shape. All varieties evaluated meet the standard for domestic market established as berry size minimum diameter 12 mm. 'BRS Clara' does not meet the export requirements of diameter. Berries of the red grapes 'BRS Morena' and 'Crimson Seedless' are firmer. The pH, titratable acidity, and soluble solids meet the official standards. Larger clusters are less acidic and present higher soluble solids/titratable acidity ratios implying that they are the sweetest type when ripe.

Yield and quality of grapes cultivated under plastic coverings with different downy mildew control strategies

“…BRS Morena grapes cultivated based on different treatments (T) reached similar averages, with a small variation. The results obtained in this study were similar to those reported by Manfroi, Mielle, Rizzon, Barradas, and Souza () and Mascarenhas et al () and were higher than those obtained by Santos et al (). The titratable acidity (TA) presented differences only in E and T. Under BPF, SR was lower and TA was higher when compared to BSS.…”

“…Other authors, in the commercial cv. BRS Morena vineyards, obtained higher cluster weights, between 300 and 340 g (Mascarenhas, Silva, Lima, Mendonça, & Holschunh, ; Santos et al, ). Flower abortions, reducing cluster numbers and mass, and in turn reducing vineyard productivity, can be facilitated by very vigorous rootstocks, as verified by Lira, Moares, Souza, Sales, and Leão () in cv.…”

Evaluación De Los Atributos Fisicoquímicos De Uvas Bronze “Granny Val” Muscadinas Durante La Maduración

“…La mayoría de las investigaciones realizadas en frutas y vegetales indican que al aumentar los SS, la acidez disminuye. Resultados similares para algunas asociaciones fueron reportados por Mascarenhas et al (2012) quienes estudiaron la correlación entre las características de calidad de cinco cultivares de uva de mesa y encontraron una asociación signifi cativa y negativa entre el pH con los sólidos solubles, acidez titulable, relación SS/AT y fi rmeza, mientras que los SS se asociaron positivamente con la relación SS/AT y fi rmeza. La AT se asoció negativamente con la relación SS/AT y positivamente con la fi rmeza.…”

Chemical quality parameters and bioactive compound content of brazilian berries

“…Information on the quality attributes and functional properties of these small fruits can guide farmers to choose the cultivars (cvs) that could be planted, thereby enabling greater market visibility, thus adding value to the product. In addition to providing information to consumers and farmers, the characterization should also be taken into account when new breeding programs are designed (Mascarenhas et al, 2012), because genotype, cultivation system or environmental conditions could affect the metabolism and production of antioxidant compounds (Hassimotto et al, 2008;Tarazona-Díaz et al, 2011). Due to health concerns, nowadays consumers increasingly demand fresh and healthy fruits and vegetables (Rodríguez-Hidalgo et al, 2010), and it is well know that some bioactive constituents in natural plant products have the ability to protect from degenerative illnesses and the production of free radicals.…”
