Different vines situated in the Centro Experimental de Pegões, 70 Km East from Lisbon, Portugal, were subjected to Nonirrigated (NI, no water applied) and Fully-irrigated (FI, 100% of evapotranspiration rate) treatments throughout the growing season for each variety. Berries were harvested and sampled on 20th September 2010 from the four plots and the yield and quality parameters were tested. Differences between the treatments were noted with grapes from irrigated plants showing significantly higher berry weight, and volume. Whereas the non-irrigated berries showed higher levels of anthocyanin content, colour intensity, total phenolics and total acidity, than the fully irrigated. There were also differences noted between varieties in several parameters, mainly with Touriga Nacional showing a higher content in the phenolic compoundsISA/ULAmâncio, Sara Barros QueirózLaureano, OlgaRepositório da Universidade de LisboaCobb, Frederic2015-12-31T01:30:11Z20122012-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10400.5/8617engCobb, F. - Effect of irrigation on berry and skin cell wall composition in the grape varieties Touriga Nacional and Trincadeira.
