The Southern region of Brazil presents a high potential for grape production. In the past two decades, in regions with more than 900 m of altitude on the state of Santa Catarina, Brazil, the production of European grapes (Vitis vinífera L.) has been highlighted, especially for the production of hight quality wines. However, the production has been problematic due to the high precipitation rates, which increase the pressure of fungal diseases, such as downy mildew (Plasmopora viticola). Based on that, PIWI cultivars, which combines resistance to diseases, including mildews, and quality of wine, are a promising alternative to cultivate. In addition, in Santa Catarina, non-traditional altitude regions have climatic conditions suitable for the production of fine wines. To carry out this research, a project was developed in association with the Agricultural Research of Rural Extension of Santa Catarina (Brazil), the Federal University of Santa Catarina (Brazil), the Julius Kühn Institute (Germany) and the Edmund Mach Foundation (Italy). This work aimed to evaluate the performance of three PIWI cultivars (V. vinifera) in the Central Plateau of Santa Catarina, Brazil. The cvs. ‘Felicia’, ‘Calardis Blanc’, and ‘Regent’, were evaluated in the cycle of 2017/2018. The vineyard was stablished in 2015, in the Experimental Station of UFSC, Campus of Curitibanos, coordinates of 27°16'25"S and 50°30'11"W and altitude of 1000 m. The plants were conducted in vertical trellis system of 3.0 x 1.2 m, in completely randomized blocks experimental design, replicated four times consisted of ten plants The main pheenological stages (budding, full bloom, véraison and maturity), the thermal demand required, the evolution of maturation and productivity, were characterized. The phenology was accompanied using the phenological scale described by Eichhorn & Lorenz. The thermal sum was determined using the Winkler index. The daily data of temperature were obtained from meteorological station installed next to the vineyard. The maturation evolution was observed from the beginning of the maturation to the harvest. Each week, 30 berries of each cvs. were collected, with four replicates, for the extraction of the wort and determination of total soluble solids (TSS) content in °Brix, and total titratable acidity (TTA) in meq.L-1. The productivity was determined by collected of all the clusters of five plants per blocks and calculating the mean per plant (kg.plant-1) and per hectare (kg. ha-1). The average duration of the cycle was 143, 146 and 147 days; the thermal demand of 1.228,5, 1.260,9 and 1.269,2 degree-days and the productivity of 3.040,0, 7.808,0 and 1.892,6 kg.ha-1, for cvs. ‘Felicia’, ‘Calardis Blanc’ and ‘Regent’, respectively. All cvs. showed early budding, starting on september 12th and 15th, and the harvest, on february 1st, 7th and 8th of 2018, for cvs. ‘Felicia’, ‘Calardis Blanc’ and ‘Regent’ respectively. In the harvest, the TSS values were 19.2, 17.9 and 21,0 °Brix, and for TTA were 110, 107 and 112 meq.L-1, respectively for cvs. ‘Felicia’, ‘CalardisBlanc’ and ‘Regent’. This study proves that the accumulated thermal sum in Curitibanos is sufficient for cvs. to complete their cycle and achieve full maturation. Nevertheless, the relatively early budding of cvs. It is a risk factor, once it can result in losses caused by late frosts. In terms of productivity, ‘Calardis Blanc’ stood out towards the other cvs. For the second year of production, all cvs. presented productive potential. Finally, this research demonstrated that the three cvs. analyzed showed prominent potencial for the viticulture in the climatic conditions of the Central Plateau of Santa Catarina, Brazil for the production of fine wines.
La regione meridionale del Brasile presenta un alto potenziale per la produzione di uva. Negli ultimi due decenni, nelle regioni con più di 900 m di altitudine nello stato di Santa Catarina, in Brasile, la produzione di uve europee (Vitis vinífera L.) è stata evidenziato, soprattutto per la produzione di vini di alta qualità. Tuttavia, la produzione è stata problematica a causa del alti tassi di precipitazione, che aumentano la pressione delle malattie fungine, come la peronospora (Plasmopora viticola). Basato su questo, le cultivar PIWI, che combina resistenza alle malattie, tra cui muffe e qualità del vino, sono promettenti alternativa a coltivare. Inoltre, a Santa Catarina, le regioni di altitudine non tradizionali hanno condizioni climatiche adeguate la produzione di vini pregiati. Per realizzare questa ricerca, è stato sviluppato un progetto in collaborazione con la ricerca agricola di Rural Extension di Santa Catarina (Brasile), l'Università Federale di Santa Catarina (Brasile), l'Istituto Julius Kühn (Germania) e la Fondazione Edmund Mach (Italia). Questo lavoro mirava a valutare le prestazioni di tre cultivar PIWI (V. vinifera) nell'altopiano centrale di Santa Catarina, in Brasile. Il cvs. "Felicia", "Calardis Blanc" e "Regent" sono stati valutati il ciclo del 2017/2018. Il vigneto è stato istituito nel 2015, nella Experimental Station di UFSC, Campus of Curitibanos, coordinate di 27 ° 16'25 "S e 50 ° 30'11" O e altitudine di 1000 m. Le piante sono state condotte in un sistema a traliccio verticale di 3.0 x 1,2 m, in blocchi completamente randomizzati disegno sperimentale, replicato quattro volte consisteva di dieci piante Il principale fasi fenologiche (germogliamento, piena fioritura, véraison e maturità), richiesta termica richiesta, evoluzione della maturazione e la produttività, sono stati caratterizzati. La fenologia è stata accompagnata utilizzando la scala fenologica descritta da Eichhorn & Lorenz. La somma termica è stata determinata utilizzando l'indice Winkler. I dati giornalieri di temperatura sono stati ottenuti da stazione meteorologica installata vicino al vigneto. L'evoluzione della maturazione è stata osservata dall'inizio del maturazione alla raccolta. Ogni settimana, 30 bacche di ogni cvs. sono stati raccolti, con quattro repliche, per l'estrazione del mosto e determinazione del contenuto di solidi totali solidi (TSS) in ° Brix e acidità totale titolabile (TTA) in meq.L-1. Il la produttività è stata determinata dalla raccolta di tutti i cluster di cinque piante per blocchi e del calcolo della media per pianta (kg.impianto-1) e per ettaro (kg ha-1). La durata media del ciclo era di 143, 146 e 147 giorni; la richiesta termica di 1.228,5, 1.260,9 e 1.269,2 gradi giorno e la produttività di 3.040,0, 7.808,0 e 1.892,6 kg.ha-1, per cvs. ‘Felicia’, 'Calardis Blanc' e 'Regent', rispettivamente. Tutti i CV. ha mostrato i primi germogli, a partire dal 12 e 15 settembre, e il raccolto, il 1 °, 7 e 8 febbraio 2018, per cvs. "Felicia", "Calardis Blanc" e "Regent" rispettivamente. Nel raccolto, il I valori TSS erano 19.2, 17.9 e 21.0 ° Brix e per TTA erano 110, 107 e 112 meq.L-1, rispettivamente per cvs. 'Felicia', 'CalardisBlanc' e 'Regent'. Questo studio dimostra che la somma termica accumulata in Curitibanos è sufficiente per i cvs. per completare il loro ciclo e raggiungere la piena maturazione. Tuttavia, il germogliamento relativamente recente delle cvs. È un fattore di rischio, una volta che può provocare perdite causate da gelate tardive. In termini di produttività, "Calardis Blanc" si è distinto verso gli altri cv. Per il secondo anno di produzione, tutti i cvs. presentato potenziale produttivo. Infine, questa ricerca ha dimostrato che le tre cv. analizzato ha mostrato potencial prominente per la viticoltura nelle condizioni climatiche dell'altopiano centrale di Santa Catarina, in Brasile per il produzione di vini pregiati
