Aim: To obtain specific references for the nutritional diagnosis of ten essential nutrients for leaf blade and petiole of ‘red Grenache’ (Vitis vinifera L.).Methods and results: Leaf blades and petioles from 36 vineyards of ‘red Grenache’ (Vitis vinifera L.) grafted on Richter 110 were collected and analyzed at flowering and veraison between 1992 and 2008. Using the compiled data bank, nutritional references for ten elements (N, P, K, Ca, Mg, Fe, Mn, Zn, Cu and B were calculated. Optimal values were those around the central data (µ ± 0.25σ), while excessive and deficient values were those beyond the tails of the distribution (µ ± 0.84σ). Percentile calculation was performed when transformations to normal distributions became unlikely.Conclusion: References for Sufficiency Ranges (SR) and Deviation from Optimum Percentage (DOP) methods were obtained for those ten nutrients studied.Significance and impact of the study: The proposed ‘red Grenache’ references for leaf blade and petiole contribute to the improvement of the accuracy of ‘red Grenache’ grapevine nutrient diagnosis based on tissue analysis. These references are a guide to assess the nutritional status of ‘red Grenache’ grapevine around the world in general and, with higher accuracy, for the Rioja region and areas with similar vineyard conditions.

“…Leaves are usually used for plant analysis as a diagnostic tool. The nutrient content in dry matter may differ considerably between leaf blades and petioles (Christensen & Peacock, 2000;Fallahi et al, 2005;Pacheco et al, 2010;Romero et al, 2010). Sometimes the petioles are thought to be a more suitable indicator of the nutritional status (Robinson, 2000).…”

A study on grapevine cv. Sibera was carried out in a vineyard located near Kraków (Poland) in 2010 and 2011. The plants were treated with three nitrogen application rates (0, 50 and 100 kg N ha-1), administered as ammonium nitrate in a single application three weeks before flowering. Samples of leaf petioles and blades, as well as grapes, were taken. After wet microwave digestion in HNO 3 , the nutrient elements boron (B), copper (Cu), iron (Fe), zinc (Zn), manganese (Mn), molybdenum (Mo) and sodium (Na), and the trace elements aluminium (Al), barium (Ba), cadmium (Cd), chromium (Cr), lithium (Li), nickel (Ni), lead (Pb), strontium (Sr), titanium (Ti) and vanadium (V), were measured using the ICP-OES technique. Environmental factors such as temperature and available water had a significant effect on the nutrient concentration in the grapes. In the wet and warm 2010 vintage, higher amounts of B, Cu, Cd, Ti and V were measured in the leaves, and of Mn, Al, Ba and Ti in the grape juice. The dry season of 2011 increased the leaf Fe, Mn, Zn, Mo, Na, Ba, Cr, Li and Ni content, which was associated with a higher Zn, Mo, Na, Sr, Cd and Ni concentration in the grape must. The study showed that, in slightly acid soils, mineral N fertilisers containing ammonium can augment the uptake and accumulation of microelements such as Fe, Mn, Zn, Al and Ti by the grape must. In contrast, nitrogen fertilisation depressed the concentrations of some elements, such as B, Fe, Mn, Cd, Cr, Ni and Ti in the leaves. Correlations between the mineral content of the analysed plant tissues are also discussed.

“…Usually, fertilizer recommendations in agriculture are based on soil and plant analyzes (Coleman et al, 2003;Pacheco et al, 2010;McCray et al, 2013). However, since the procedure based on soil analysis has some constraints as the soil samples may not be representative of the portion of soil effectively explored by plants, the identification of nutrients that are really available to plants present some doubts (Meyer, 1981;Coleman et al, 2003;Pacheco et al, 2010;Horneck et al, 2011).…”

“…This kind of diagnosis can suit as a complement to soil analysis, allowing greater efficiency in fertilizer applications, including the economic ones (Chapman and Brown, 1950;Malavolta et al, 1997;McCray et al, 2013). The interpretation of leaf analysis uses essentially reference values for specific levels of productivity and quality (such as the Critical Concentrations and the Sufficiency Nutrient Range Limits) (Pacheco et al, 2010). These comparisons based on the standard values are a basic methodology which considers each nutrient independently and this way difficult the application of the concept of nutritional balance, since it can only identify a nutrient at each time (Jones, 1981;Beverly, 1991).…”

SUMMARYThe Diagnosis and Recommendation Integrated System (DRIS) is an alternative tool for the evaluation of nutritional status and fertilizer recommendation of several crops. However, as this methodology implies the establishment of norms or standards, without which one cannot infer about the nutritional status of a crop, in Portugal this tool has little application. The aim of this study was to establish preliminary DRIS norms for vineyards in Portugal. From 2007 to 2009, petiole samples were collected on a set of 199 selected plots. The DRIS norms were established according to the proposed by Beaufils (1973), based on the results of the laboratory procedures. The results suggest the need for further studies in order to validate the DRIS norms presented. In the future it will be important to increase the number of observations for the establishment of DRIS norms, as well as to determine the relevance of establishing specific nutritional standard according the edaphic, climatic and varietal variability of Portuguese wine regions. RESUMOO Sistema Integrado de Diagnóstico e de Recomendação, em língua inglesa Diagnosis and Recommendation Integrated System (DRIS) constitui uma ferramenta alternativa para a avaliação do estado nutricional e a fundamentação da recomendação de fertilização de diversas culturas. Todavia, em Portugal este é um recurso ainda pouco divulgado uma vez que tal metodologia implica o estabelecimento de valores de referência ou normas, sem os quais não se poderá inferir sobre o estado nutricional de uma dada cultura. Neste trabalho, pretendeu-se estabelecer normas DRIS para a cultura da vinha em Portugal Continental. Para tal, entre 2007 e 2009, selecionou-se um conjunto de parcelas, nas quais foram recolhidas 199 amostras de pecíolos. As normas DRIS foram calculadas de acordo com a metodologia proposta por Beaufils (1973), a partir dos resultados da análise laboratorial. Os resultados obtidos sugerem a necessidade de estudos posteriores, com vista à validação das normas DRIS apresentadas. Futuramente será importante aumentar o número de parcelas consideradas para o estabelecimento das normas DRIS, assim como averiguar a pertinência do estabelecimento de padrões nutricionais mais específicos, de acordo com a variabilidade edafoclimática e varietal das regiões vitivinícolas portuguesas.
