Ensaio foi conduzido com viderias da cultivar 'Niagara Rosada' (Vitis labrusca L. X Vitis vinifera L.) com 7 anos de idade, no município de Jundiaí, SP, (23°12' de latitude sul e 46°33' de longitude oeste e 715 m de altitude), situadas sobre um Regossolo unidade Currupira, com os objetivos de: (1) determinar as quantidades de nutrientes absorvidos pela videira nos diferentes estádios de desenvolvimento; (2) avaliar a exportação de nutrientes pela cultura durante um ciclo vegetativo. Após a brotação da videira, foram realizadas 17 coletas quinzenais de material. Foram coletadas e separadas as folhas das partes terminal e basal, sarmentos das partes terminal e basal e cachos. No material coletado foram determinados os teores de micronutrientes, com exceção do molibdênio e cloro. Curvas representativas das concentraçoes dos nutrientes nas partes da planta, em função da idade, foram obtidas a partir dos dados calculados através de equações de regressão. Pelos pontos de máximo estimaram-se as quantidades máximas de nutrientes extraídos. Concluiu-se que: - A concentração dos nutrientes é sempre maior nas folhas do que nos sarmentos e existem diferenças nas concentrações de nutrientes das folhas, sarmentos e cachos, em função da idade. - Os acúmulos máximos de nutrientes nas folhas, sarmentos e cachos ocorrem nas seguintes idades: - A exportação de nutrientes em mg por planta pelos cachos e sarmentos removidos pelas colheitas e poda é a seguinte.

Grapevine seedlings<em> Vitis vinifera</em> were grown in a greenhouse under optimum conditions (soil moisture ca 70%) and under drought stress (soil moisture ca 35%). In addition, some of the plants subjected to drought underwent subsequent regeneration under optimum conditions. Drought stress caused accumulation of total phenolic compounds in grapevine roots, which may indicate that these compounds play an important role in the adaptation of roots to growth under stress conditions. Phenolic acids found in the roots occurred in the ester-bound form only. p-coumaric acid was present in the highest concentrations (6.2 to 10.5 µg/g fresh matter). The content of ferulic acid was lower, ranging from 2.4 to 4.6 µg/g fresh matter. The lowest concentration in grapevine roots was achieved by caffeic acid (2.4 to 2.9 µg/g fresh matter). The levels of p-coumaric and ferulic acids in roots rose significantly under the drought stress, while the concentration of caffeic acid increased during the post-drought recovery period. This may suggest that some of the phenolic acids protect plants under stress conditions. All the extracts from grapevine roots had antioxidative properties, but the antiradical activity of the extracts obtained from roots subjected to drought stress was inferior to the control. The same extracts were also characterised by depressed reducing power. The results imply that tolerance of grapevine to soil drought may be associated with the value of antioxidative potential in root tissues of these plants.
