Resumo -O objetivo deste trabalho foi avaliar o desempenho vitícola de 12 variedades autóctones italianas cultivadas a 1.400 m de altitude, em São Joaquim, SC. As seguintes variedades foram avaliadas em três ciclos: Prosecco, Verdicchio e Vermentino (brancas); e Aglianico, Aleatico, Ancellotta, Lambrusco Grasparossa, Montepulciano, Negroamaro, Rebo, Sagrantino e Sangiovese (tintas). Utilizou-se o delineamento experimental inteiramente casualizado, com cinco repetições de oito plantas para cada variedade. Os estádios fenológicos analisados foram: brotação, floração, mudança de cor das bagas e maturidade. No momento da colheita, avaliaram-se: produtividade e produção por planta, teor de sólidos solúveis totais (ºBrix), acidez total titulável (meq L -1 ), pH, e teores de antocianinas e de polifenóis totais. A amplitude térmica em torno de 10°C, durante a maturação, influenciou positivamente a qualidade da uva. As variedades brancas mais bem adaptadas às condições de São Joaquim foram a Vermentino e a Verdicchio, com produtividades acima de 3,9 Mg ha -1 , sólidos solúveis acima de 18°Brix e teores de polifenóis totais acima de 500 mg L -1 . As variedades tintas mais bem adaptadas foram a Sangiovese, a Sagrantino e a Montepulciano, com produtividades em torno de 6 Mg ha -1 , sólidos solúveis entre 19 e 21,5°Brix e teores de polifenóis totais acima de 780 mg L -1 . As baixas temperaturas durante a brotação e o volume de precipitação pluvial são os aspectos climáticos mais limitantes ao cultivo das variedades avaliadas, em São Joaquim.Termos para indexação: Vitis vinifera, desempenho agronômico, fenologia, maturação fenólica, maturação tecnológica, "terroir". Viticultural performance of native Italian varieties in high-altitude conditions in Southern BrazilAbstract -The objective of this work was to evaluate the viticultural performance of 12 native Italian varieties, cultivated at 1,400 m of altitude in São Joaquim, state of Santa Catarina, Brazil. The following varieties were evaluated during three cycles: Prosecco, Verdicchio, and Vermentino (white); and Aglianico, Aleatico, Ancellotta, Lambrusco Grasparossa, Montepulciano, Negroamaro, Rebo, Sagrantino, and Sangiovese (red). A completely randomized design was used, with five replicates of eight plants for each variety. The phenological stages evaluated were: budbreak, full bloom, veraison, and maturity. At harvest, the following were evaluated: yield and productivity per plant, total soluble solids (°Brix), titratable total acidity (meq L -1 ), pH, and contents of anthocyanin and total polyphenol. Thermal amplitude around 10°C during maturation positively influenced grape quality. The white varieties better adapted to the conditions of São Joaquim were Vermentino and Verdicchio, with yields above 3.9 Mg ha -1 , soluble solids above 18°Brix, and total polyphenol contents above 500 mg L -1 . The red varieties better adapted were Sangiovese, Sagrantino, and Montepulciano, with yields around 6 Mg ha -1 , soluble solids between 19 and 21.5°Brix, and total polyphenol cont...

“…A long-lasting debate on the influence of soil and rootstock on grapevine growth was held (Mackenzie & Christy 2005;Andre´s-dePrado et al 2007;Sampaio 2007;Trought et al 2008;Ubalde et al 2010). Nevertheless, no studies so far have addressed the effects of these factors on the transcriptome of the scion.…”

“…The influence of various soil properties, including texture, depth, chemical composition, waterholding capacity, water availability and its importance for the grapevine growth, and the characteristics and qualities of the wine have been widely studied (Turner & Creasy 2003;Andre´s-de-Prado et al 2007;Trought et al 2008). For instance, it has been shown that soil water availability influences the grapevine hormonal equilibrium, while nitrogen, abiotic stresses, and water supply control the biosynthesis of flavonols and of other phenylpropanoid-derived products (Kao et al 2002;Ubalde et al 2010;DeLuc et al 2011).…”

Rootstock and soil induce transcriptome modulation of phenylpropanoid pathway in grape leaves

et al. 2013

Soil qualities and rootstocks are among the main factors that have been acknowledged to influence grape development as well as fruit and wine composition. Despite the role of soil and rootstock in establishing a successful vineyard in terms of grape quality, almost no molecular evidence linking soil and rootstock properties to the gene expression have been reported. The transcriptome variation in response to different soils and rootstocks was investigated through microarray technology. The cv. Pinot Noir was grown on different soils: sand, turf, and vineyard soil. The plants were grafted on the contrasting 101-14 and 1103 Paulsen rootstocks. The modulation of genes' expression in response to different soils and rootstocks was evaluated considering their potential impact on primary (carbohydrate) and secondary (phenylpropanoid) metabolisms. This study highlights a link among soil composition, rootstock, and gene expression. The results open a perspective for a molecular interpretation of the interaction between soil and grapevine.

“…A ausência de correlação entre sólidos solúveis e pH do mosto pode ser atribuída, parcialmente, a variações das condições meteorológicas entre as safras, as quais tem maior efeito sobre o teor de sólidos solúveis do que sobre o pH do mosto. Ubalde et al (2010) (1) Médias seguidas por letras iguais na linha, minúscula para solo e maiúscula para safra, não diferem pelo teste DMS, a 5% de probabilidade. Na safra 2010/2011, o teor de taninos correlacionouse negativamente ao teor de antocianinas, em ambos os solos.…”

Morlat & Bodin (2006) O clima do local, segundo a classificação de Köppen, é do tipo Cfb, mesotérmico, úmido, sem estação seca, com verão fresco (< 22ºC).…”

Resumo -O objetivo deste trabalho foi avaliar os efeitos das condições meteorológicas e do tipo de solo sobre características físico-químicas e compostos fenólicos da uva 'Cabernet Sauvignon' (Vitis vinifera Weather and soil effects on the composition of 'Cabernet Sauvignon' grapeAbstract -The objective of this work was to evaluate the effects of weather and soil type on the physicochemical characteristics and phenolic compounds of the 'Cabernet Sauvignon' grape (Vitis vinifera). The experiment was carried out in a vineyard established in 2003, grafted onto 'Paulsen 1103', and conducted in the cordon system. Two soils were selected in the vineyard: Typic Dystrudepts and Pachic Humudepts. The effect of weather (rainfall, and minimum and maximum temperature) was evaluated in the seasons 2008/2009, 2009/2010, and 2010/2011. Soil physical and chemical properties, soluble solids, titratable acidity and pH of the wort were determined, as well as the index of total polyphenols, and anthocyanin and tannin contents of the grape. The factors soil and meteorological conditions (crop seasons) were arranged in a 2x3 factorial. Except for the total polyphenol content, weather and soil type affect the physicochemical characteristics of 'Cabernet Sauvignon'. The effect of weather is more pronounced than the effect of soil type. Lower rainfall and higher temperature ranges favor the accumulation of soluble solids in the 'Cabernet Sauvignon' grape. Higher rainfall favors the increase of wine acidity.
