ABSTRACT.
Excessive vine growth not only negatively impacts fruit composition but also fosters bunch rot incidence. The goal of our study was to improve Vitis vinifera (Tannat) grape and wine composition and decrease bunch rot incidence by achieving adequate vine vegetative growth in a humid climate. Our approach was to use under-trellis cover crops (UTCC) to limit vine water availability and reduce excessive vine growth. We tested UTCC consisting of full cover of the vineyard soil with red fescue (Festuca rubra) versus conventional alleyway red fescue with 1.0 m wide weed-free strips under the trellis (H). As excessive competition with grapevines remains the main reason for UTCC rejection, this strategy was tested in combination with two irrigation schedules?irrigation to avoid water restriction at bloom (Ir) vs. no early irrigation?and two nitrogen inputs (0 vs. 100 kg N ha−1) over three growing seasons in southern Uruguay. Treatments were arranged in a split-split-plot randomized block design with cover crop schemes as main plots, water availability as subplots and nitrogen inputs as sub-subplots. Shoot growth rate, mid-day stem water potential (Ψstem), berry size and berry composition were monitored over the season, as well as final yield, cluster and pruning weights. UTCC significantly reduced vine vegetative growth, while no significant differences were detected between H and UTCC when irrigation took place early in the season. Even nitrogen input showed positive effects on grapevine vegetative growth in some cases, water availability at bloom was the key driver of vegetative growth. UTCC treatments increased grape soluble solids (TSS) in the last two out of three seasons and consistently increased anthocyanin concentration in grapes. Independent of vegetative growth, strong differences in bunch rot incidence were detected between H and UTCC treatments. Seasonal variations in water status and/or free amino nitrogen content of grapes may have a relevant impact on disease susceptibility at harvest.

RESUMEN.
Tannat es la principal variedad de uva tinta cultivada en Uruguay para la producción de vinos destinados al mercado local y la exportación. En un proceso de reconversión de antiguas plantaciones envirosadas, en la década de los 70s comienzan a introducirse clones seleccionados en Francia, siendo el 398 el más adoptado aún sin experiencia previa de su comportamiento en el país. A fin de comparar el desempeño cualitativo y cuantitativo, ocho clones ENTAV-INRA 398, 399, 472, 474, 475, 717, 794 y 944 fueron plantados, quince plantas por parcela, en bloques al azar con ocho repeticiones. El ensayo, conducido en espaldera alta, con poda larga y sobre portainjerto SO4 , fue evaluado de 2005 a 2010. Diez plantas por parcela fueron raleadas antes de envero y cinco permanecieron con toda su producción. Se evaluó rendimiento, peso y número de racimos por planta junto a parámetros cualitativos de uvas y vinos. Se realizaron análisis sensoriales descriptivos anualmente sobre los vinos por panelistas especializados. Los clones 398, 399 y 475 fueron más productivos, exhibiendo diferencias significativas con el 474. Las uvas de los clones 474 y 717 tuvieron las mejores calidades independientemente del rendimiento. Sus uvas tuvieron los mayores contenidos de sólidos solubles y de antocianos totales y fácilmente extraíbles. Los vinos de estos clones, junto al 398, mostraron los aromas más frutados, más estructurados y menor astringencia. Ello sugiere que ambos deberían considerarse para futuras plantaciones destinadas a vinos de calidad en las condiciones agro-climáticas del Uruguay.

SUMMARY.
Tannat is the main red wine variety cultivated in Uruguay for the production of wines for the domestic market as well as for export. In a process of reconversion of old virus infected plantations, clones selected in France began to be introduced in the 70´s. Clone 398 was the most adopted, without previous experience of its behavior in the country. In order to compare qualitative and quantitative performance, eight French Tannat ENTAV-INRA clones 398, 399, 472, 474, 475, 717, 794 and 944 were planted, fifteen plants per plot, in a randomized block design with eight replicates. The trial conducted on VSP trellis, with long pruning, and on rootstock SO4 , was evaluated from 2005 to 2010. Ten plants per plot were thinned before veraison, and five remained with all their production. Yield, weight, and number of clusters per plant were evaluated, along with qualitative parameters of grapes and wines. Descriptive sensorial analyzes were carried out annually on wines by specialized panelists. Clones 398, 399 and 475 were more productive, showing significant differences with 474. Clones 474 and 717 had the best grape and wine quality independently of crop load. Their grapes had the highest contents of soluble solids and total and easily removable anthocyanins. The wines of these clones, along with 398, had the most fruity aromas, structure, and minor astringency. This suggests that both clones should be considered for future plantations for high quality wines under the agro-climatic conditions of Uruguay. MenosRESUMEN.
