São Francisco Valley (SFV) is located in Northeastern Brazil, in a tropical semi-arid region where one vine can produce two harvests per year, due to high temperatures, solar radiation rates, and irrigation throughout the year. This is the main characteristic iffering this from other winegrowing region in the world. The objective of this study was to characterize volatile profiles of sparkling wines produced by the traditional method, using Chenin Blanc and Syrah grapes, the two main varieties used for white and red wines, respectively, grown in the region. The sparkling wines remained on lees for six months maturing. The sparkling wines were characterized by the parameters density, pH, total titratable and volatile acidities, residual sugars, dry extract, alcohol content, total phenolic compounds, in vitro antioxidant activity and volatile fraction. The volatile fraction extraction was performed by the HS-SPME technique and tentative identification of the volatile compounds was carried out with GC-MS using the scan mode. A total of 33 volatile compounds were identified, among them 11 alcohols, 13 esters, five carboxylic acids, and four different chemical classes. The volatile profile of Chenin Blanc sparkling wine was associated mainly to 2,3-butanediol, 3-ethoxypropan-1-ol, diethyl succinate, and ethyl decanoate, while Syrah sparkling wine was characterized by benzaldehyde, butyric acid, and some acetates. This study reported for the first time volatile profiles of traditional sparkling wines from SFV, as new products, contributing to better understand the quality potential of these beverages for a tropical semi-arid region.

Plantas de Seringueira (Hevea spp.) oriundas dos clones IAN 717, IAN 873, IAN 2903, IAN 3087, IAN 6323 e Fx 3899 foram cultivadas em casa de vegetacao e submetidas a deficits hidricos crescentes no solo com objetivo de avaliar comparativamente os seus efeitos sobre o potencial hidrico foliar, resistencia estomatica, fotossintese, transpiracao e teor de clorofila. Os resultados mostraram que o decrescimo do potencial hidrico no solo reduziram linear e diferentemente o potencial hidrico foliar de todos os clones. Os maiores decrescimo foram encontrados nos clones IAN 717, IAN 3087 e IAN 873 e o menor no IAN 6323. potenciais hidricos foliares entre - 1,6 e -2,0 MPa causaram em todos os clones um rapido aumento da resistencia estomatica e as maiores reducoes da transpiracao corresponderam ao clone IAN 6323. O ponto de compensacao hidrico mais alto foi -2,35 MPa em IAN 2903 e Fx 3899 e o mais baixo - 3,18 MPa de IAN 6323. O clone IAN 6323 apresentou um eficiente mecanismo de prevencao a seca e uma efetiva estabilidade do aparelho fotossintetico sob condicoes de estresse. Os clones IAN 717 e IAN 3087 foram, num nivel inferior, tambem resistentes. |
