“…As a general trend, the highest phenolic concentrations (anthocyanins, in particular) in berries are found in soils with higher clay and/or organic matter content (Choné et al 2001;Tesic et al 2001;Morlat and Bodin 2006;Ramos et al 2015). In addition, a clay-induced soil effect is often greater in wet and intermediate years than in dry years when abundant ABA biosynthesis controls plant responses to drought, independently from soil properties.…”

Grapevine adaptations to water-stress are described, by focusing on soil/root interactions and root-to-shoot signaling to control both plant water relations and fruit ripening process.Root response to drought, tolerance of available rootstock germoplasm, mechanisms of embolism formation and repair in root, aquaporin control of plant water relations, and abscisic acid biosynthesis and delivery are highlighted, by reviewing recent insights coming from either (eco)physiological literature or viticultural assays addressing vineyard-soil relationships.

“…(23) apunta que este tipo de vendimia es viable a distintas escalas de producción, desde pequeños hasta grandes elaboradores. Algunos de los factores del medio a los que puede deberse la variabilidad intraparcela son: (i) la topografía (9, 24); (ii) la profundidad del suelo (25); (iii) la capacidad de retención de agua del suelo (22,26) y/o (iv) el contenido en nitrógeno del suelo (27,28). Además, esta variabilidad tiene efectos tanto en el rendimiento (29) como en la calidad de la uva (30), siguiendo (en estos dos últimos ensayos) un patrón parecido año tras año.…”

Resumen. Los factores naturales que definen el terroir son los principales responsables de la variabilidad observada entre plantas de una misma parcela (variabilidad intraparcela) o de distintas fincas (variabilidad interparcelas). En el presente trabajo se propone una metodología de zonificación del terroir, presentándose también su relación con algunas características vegeto-productivas del viñedo y con el Índice de Vegetación de Diferencia Normalizada (NDVI). La zonificación de los elementos del medio se ha llevado a cabo a partir de la fotointerpretación aérea mientras que la representación gráfica del NDVI se realiza partiendo de una imagen multiespectral capturada por el satélite Pleiades, de 0,5 metros de resolución espacial. Comparando los datos vegeto-productivos recogidos en las 4 parcelas de estudio, se ha observado que existen sectores, relacionados con zonas de deposición de material y asociados a suelos de carácter fluvéntico, con tendencia a ser más vigorosos, más productivos y con uvas de menor contenido fenólico y de menor pH. Por otro lado, analizando cada parcela de manera independiente, se observa que la distribución espacial del NDVI sigue un patrón semejante a la zonificación de los elementos del medio, algo que recomendaría hacer un uso de este índice por sectores previamente discriminados conforme a una cierta uniformidad del terroir.Abstract. The natural factors that define terroir are main responsible for the variabililty observed between plants of the same plot (intra-plot variability) or of different farms (variability between plots). A methodology of terroir zoning is proposed, also is presented its relation with some vegeto-productive characteristics of vineyard and with the Normalized Difference Vegetation Index (NDVI). Zoning of natural factors has been carried out from aerial photointerpretation while graphic representation of NDVI was made starting from a multispectral image (0,5 meters of spatial resolution) captured by the Pleiades satellite. Comparing the vegetative and productive data collected in the four study plots, it has been observed that there are sectors related to deposition areas and associated with fluvent soils, with a tendency to be more vigorous, more productive and with grapes of lower phenolic content and lower pH. On the other hand, analyzing each plot independently, it is observed that NDVI spatial distribution follows a similar pattern to the natural factors zoning, something that would recommend making use of NDVI by sectors previously discriminated according to certain terroir uniformity. IntroducciónLos primeros estudios científicos relacionados con los elementos del medio vitícola y sus interacciones se llevan a cabo en el último cuarto del siglo XX, pudiendo considerarse la tesis doctoral del profesor René Morlat (1) uno de los estudios pioneros sobre la zonificación del terroir vitícola en el sentido moderno del término. El citado trabajo se desarrolla en la zona media del valle del Loira, siendo los países europeos los que tradicionalmente más impor...

“…Additionally, it can be seen that in the treatment without water application the TPI tends to be the highest in each season ( Table 2). The importance of high TPI values in the must is in their relationship with the positive effects on the future quality of the wine (Choné et al, 2001). Regardless of the higher fruit production, the larger number of clusters per plant and larger berry diameter -which could have negatively affected the quality -the must obtained in the 2005-2006 season was of higher quality, according to the measured variables and TPI levels.…”
