“…Lamine et al [ 56 ] used the PCA method to discriminate Tunisian grape cultivars and reported high morphological diversity. Nassur et al [ 57 ] used the PCA method on grape cultivars in Brazil, and based on principal component analysis (PCA), all grape cultivars were discriminated and high morphological variation was observed among the accessions. Istrate et al [ 58 ] used applications of the principal component analysis (PCA) at grape varieties from the serogroup Coarnă neagră for establishing phenotypical variability and found great diversity among cultivars.…”

Morphology is the most visible and distinct character of plant organs and is accepted as one of the most important tools for plant biologists, plant breeders and growers. A number of methods based on plant morphology are applied to discriminate in particular close cultivars. In this study, image processing analysis was used on 20 grape cultivars (“Amasya beyazı“, “Antep karası“, “Bahçeli karası”, “Çavuş“, “Cevşen“, “Crimson“, “Dimrit“, “Erenköy beyazı“, “Hafızali“, “Karaşabi“, “Kırmızı“, “İzabella (Isabella) “, “Morşabi“, “Müşgüle“, “Nuniya“, “Royal“, “Sultani çekirdeksiz (Sultanina)“, “Yalova incisi“, “Yerli beyazv“, “Yuvarlak çekirdeksiz“) to classify them. According to image processing analysis, the longest and the greatest projected area values were observed in “Antep karası“ cultivar. The “Sultani çekirdeksiz“ cultivar had the least geometric mean diameter. The greatest sphericity ratios were observed in “Yerli beyaz“, “Erenköy beyazı“ and “Amasya beyazı“ cultivars. According to principal component analysis, dimensional attributes were identified as the most significant source of variation discriminant grape cultivars from each other. Morphological differences between the cultivars were explained by sphericity and elongation variables. According to elliptic Fourier analysis (EFA) results, grape morphology largely looks like ellipse and sphere. However, there are some cultivars that look similar to a water drop. The cultivars with similar morphology were identified by a pair-wise comparison test conducted with the use of linear discriminant analysis, and they were presented in a scatter plot. According to cluster analysis, present grape cultivars were classified into seven sub-groups, which indicated great diversity.

“…Similar results were found by Lima et al (2014) who evaluated juices of the VIO and IP cultivars in the São Francisco Valley and found higher contentes of anthocyanins in VIO juices (464.00 mg L -1 ) and lower values in IP (29.00 mg L -1 ). Nassur, Pereira, Alves and Lima (2014) evaluated juices from the COR and IP cultivars on different rootstocks in Petrolina-PE and found values from 22.80 mg L -1 to 168.00 mg L -1 for COR and 35.12 mg L -1 at 43.53 mg L -1 for PI.…”

The objective of the present study was to evaluate grape juices from different cultivars obtained by two different technologies: steam juicer system (S1) and enzymatic system (S2). The beverages were evaluated for physicochemical and sensory characteristics and their adequacy to the identity and quality standards of whole grape juice. Experiments were carried out in the 2018 and 2019 harvests with the grape cultivars BRS Rúbea (RUB), BRS Cora (COR), BRS Violeta (VIO), BRS Carmem (CAR), BRS Magna (MAG), Bordô (BOR), Isabel (ISA), Isabel Precoce (IP), Concord (CON), Concord Clone 30 (C30) and SCS 421 Paulina (SCSP). Treatments followed factorial design (cultivars x extraction system). S1 resulted in juices with lower soluble solids content; on average, a reduction of 3.12 °Brix in 2018 and 2.30 °Brix compared with the original content in grapes. Among S1 juices, only VIO and MAG in 2018, and VIO and CAR in 2019 achieved the minimum value of soluble solids (14 °Brix) established by the Brazilian legislation. Juices of SCSP and CON in 2018 and C30, CON and RUB in 2019 presented values lower than 14 °Brix, independent of the extraction system. S2 juices were characterized by higher values of total acidity, soluble solids, reducing sugars, anthocyanins, global impression, and equilibrium, as well as lower values of lightness for most of the cultivars.

The São Francisco Valley, in Brazil, is a region with harvest of grapes more than once a year due to the peculiar climate condition, being important to evaluate new agronomic variables for the vines and elucidade its influence on wine quality and nutritional compounds. Syrah vines grafted on different rootstocks (IAC-313 and Paulsen 1103) were cultivated in semi-arid conditions in Petrolina, PE, Brazil, and the quality of the wine was evaluated for color, sugars, acidity, phenolic compounds, antioxidant activity and the presence and contents of eight biogenic amines by HPLC (putrescine (PUT) dihydrochloride, spermidine (SPD) trihydrochloride, spermine (SPM) tetrahydrochloride, agmatine (AGM) sulfate, cadaverine (CAD) dihydrochloride, serotonine (SRT) hydrochloride, histamine (HIM) dihydrochloride, tyramine (TYM), tryptamine (TRM) and 2-phenylethylamine (PHM) dihydrochloride). For total sugars, color and antocyanins content in the evaluated wines, no effect from the rootstock was observed. For the wine produced with grapes from Syrah wines grafted on Paulsen 1103 rootstock, was observed the presence of putrescine, agmatine and phenylethylamine with the contents of 8.04, 0.15 and 0.22 µg mL-¹, respectively. The use of the rootstock IAC-313 on Syrah vines at the São Francisco Valley semi-arid conditions, Brazil, resulted in wines with a statistical lower pH and soluble solid contents and higher antioxidant activity and phenolic contents, with only the presence of putrescine of the studied biogenic amines.
