Abstract The main objective of this study was to acquire agronomic knowledge about the effects of irrigation with saline reclaimed (RW) and desalinated DESERT (DW) water and different irrigation strategies: control full irrigation (FI) and regulated deficit irrigation (RDI) on leaf nutrients, tree growth and fruit quality and yield of almond trees in pots. Our results showed that RW had the highest concentration of some valuable agronomic nutrients such as N, but also of phytotoxic elements (Na and Cl−). Na leaf concentration on RW treatments reached toxic levels, especially under RDI, and toxicity symptoms were shown. Regarding tree growth, cumulate trunk diameter on RW-RDI was significantly lower than on the control treatment and shoot growth was reduced from the beginning of the irrigation season in RW treatments. Maximum yield was reached on RW-FI, 18% higher than the control treatment. However, RDI strategies influenced negatively on yield, being 23% less in RW and 7% less in DW although water productivity was not significantly reduced by water stress. These findings manifest that the combination of RW and RDI can be a promising future practice for almond irrigation, but long-term studies to establish suitable management practices must be developed.

[email protected]     1 ABSTRACT   Deficit irrigation is used to control grapevine vegetative vigor and the grape composition can be influenced by soil water content. The minerals contained in the grapes are responsible for the physicochemical properties and stability of the wine. Therefore, the aim of this work was to evaluate the effects of irrigation strategies on the properties of ‘Syrah’ wines produced in São Francisco Valley, Brazil. The irrigation treatments used were FI (full irrigation), RDI (regulated deficit irrigation), and DI (deficit irrigation). Winemaking was performed by traditional methods, followed by stabilization and bottling. Density, alcohol content, pH, total and volatile acidity, total and free sulfur dioxide, total polyphenols index, color intensity, and total anthocyanin content were determined, as well as the contents of Ca, Mg, P, K, Na, Mn, Fe, Cu, Zn, Cd, Cr, Ni, and Pb. The properties of wines were influenced by irrigation strategies, except for the content of total anthocyanin, Mg, P, Na, Cu, and Mn. The contents of Cd, Cr, Fe, and Zn were similar in the vines. The wines demonstrated varied properties with different typicalities. Irrigation strategies can be recommended for different products, FI for young and cheap, and DI and RDI for aged and more expensive wines.   Keywords: Vitis vinifera L., grape, water availability, tropical wine.     OLIVEIRA, V.

INFLUÊNCIA DE ESTRATÉGIAS DE IRRIGAÇÃO NAS PROPRIEDADES FÍSICO-QUÍMICAS DO VINHO ‘SYRAH’ PRODUZIDO NO VALE DO SÃO FRANCISCO           2 RESUMO   A irrigação com déficit é utilizada para controlar o vigor vegetativo da videira, e a composição da uva pode ser influenciada pela umidade do solo. Os minerais presentes nas uvas são responsáveis pelas propriedades físico-químicas e pela estabilidade do vinho. Portanto, o objetivo deste trabalho foi avaliar os efeitos de estratégias de irrigação sobre as propriedades do vinho ‘Syrah’ produzido no Vale do São Francisco, Brasil. As estratégias de irrigação utilizadas foram IP (irrigação plena), IDC (irrigação com déficit controlado) e ID (irrigação com déficit). A elaboração de vinhos foi realizada por métodos tradicionais, seguido de estabilização e engarrafamento. A densidade, teor de álcool, pH, acidez total e volátil, dióxido de total e livre de enxofre, o índice total de polifenóis, a intensidade da cor, conteúdo total de antocianina e concentrações de Ca, Mg, P, K, Na, Mn, Fe, Cu e Zn, Cd, Cr, Ni e Pb foram determinadas. As propriedades dos vinhos foram influenciadas pelas estratégias de irrigação, exceto os teores totais de antocianinas, e de Mg, P, Na, Cu e Mn. Os níveis de Cd, Cr, Fe e Zn foram semelhantes nos vinhos. Os vinhos demonstraram propriedades variadas com diferentes tipicidades. As estratégias de irrigação podem ser recomendadas para a obtenção de diferentes produtos, sendo a IP para vinhos jovens e baratos, e o ID e IDC para vinhos envelhecidos e mais caros.   Palavras chave: Vitis vinifera L., uva, disponibilidade de água, vinho tropical.
