Abstract
Cell walls of seaweeds contain a wide number of organic and inorganic constituents, of which polysaccharides have important biological activity. Some researchers suggest that polysaccharides from seaweeds can behave as biotic elicitors in viticulture, triggering the synthesis of phenolic compounds in leaves and grape berries. The mechanism of action of seaweeds after a foliar application to grapevines is not fully understood but it is discussed in this review. An overview of the recent research focused on the effects of seaweeds foliar applications on grapevine productivity, on grape and wine quality is included as well as a short-term future perspective for the research in this field.

Cell walls of seaweeds contain a wide number of organic and inorganic constituents, of which polysaccharides have important biological activity
Gutiérrez-Gamboa et al (2020c) reported that a seaweed extract applied at 0.25 % (v/v) to ‘Tempranillo’ grapevines increased the content of several amino acids compared to the application at 0.50 % (v/v) of the same extract on a dry season
Mechanisms of action of seaweed products applied to the grapevines have not been fully studied but this review provides an overview on their effects as elicitors and foliar fertilizers

As paredes celulares das algas marinhas contêm um elevado número de constituintes orgânicos e inorgânicos, dos quais os polissacáridos têm importante atividade biológica. É incluída uma visão geral dos trabalhos de investigação recentes sobre os efeitos das algas marinhas aplicadas, por via foliar, na produtividade da vinha, na qualidade da uva e do vinho, assim como uma perspetiva de estudo futuro de curto prazo para a investigação neste campo Palavras-chave: aminoácidos, algas marinhas, polissacáridos, elicitação, fertilizante foliar, compostos fenólicos, compostos voláteis
