Traditionally, wines are produced in temperate climate zones, with one harvest per year. Tropical wines are a new concept of vitiviniculture that is being developed, principally in Brazil. The new Brazilian frontier is located in the northeast region (São Francisco River Valley) in Pernambuco State, close to the equator, between 8 and 9 degrees S. Compared with other Brazilian and worldwide vineyards, the grapes of this region possess peculiar characteristics. The aim of this work is a preliminary study of commercial São Francisco River Valley wines, analyzing their metabolite profiles by (1)H NMR and chemometric methods.

RESUMO:Objetivou-se determinar a evapotranspiração da cultura e o coeficiente de cultivo da cana-de-açúcar sobre estresse salino no desenvolvimento inicial. O experimento foi conduzido no Departamento de Engenharia Agrícola DEAGRI/UFRPE), Recife -PE. Os tratamentos foram compostos por duas lâminas de reposição da evapotranspiração da cultura (100 e 120% ETc) e cinco níveis de salinidade da água de irrigação (0,5; 2,0; 4,0; 6,0; 8,0 dS
