| ABSTRACT Seven species of Vitis L., V. champinii Planchon, V. cinerea (Engelm in Gray) Engelm, V. girdiana Munson, V. labrusca L., V. rotundifolia Michaux, V. rupestres Scheels and V. vinifera L. were studied with the purpose of complementing the karyomorphometric information for further comparative analyses. Based on ideograms and on chromosome measures obtained it was possible to see several differences among the species, which were enough to distinguish at least V. champinii and V. girdiana from the others as well as V. labrusca for the lowest measures and V. rotundifolia for the highest mean value of arm ratio. It seems that during the species diversification process the most crucial differences among them did not involve drastic changes in chromosome... |

| RESUMOSão apresentadas normas DRIS preliminares e derivados níveis críticos de nutrientes no tecido foliar (NC) para a videira ‘NiagaraRosada’ enxertada sobre o porta-enxerto ‘IAC 766’, nas condições de cultivo da região de Jundiaí-SP. As normas DRIS e os NCs foram obtidos a partir de um banco de dados com 116 registros, relacionando produtividade e teores foliares de N, P, K, Ca e Mg das videiras. Esses registros foram obtidos em experimentos de adubação e em um levantamento do estado nutricional de videiras realizados na região de Jundiaí, durante quatro ciclos de produção. Os registros foram separados em duas subpopulações: alto (>26 t/ha), e baixo rendimento (<26 t/ha) e as normas DRIS foram calculadas de acordo com os procedimentos... |

| ABSTRACT It has been demonstrated that rootstocks can influence grape characteristics, but there are few data in literature about the rootstocks influence in the wine characteristics, especially in wines elaborated with Vitis labrusca or hybrid grapes. This study evaluated the influence of ‘IAC 766’ and ‘106-8 Mgt’ rootstocks on the physicochemical characteristics of ‘Bordô’, ‘Isabel’ and ‘IAC 138-22 ‘Máximo’ musts and wines. The musts were evaluated for pH, soluble solids, total acidity and soluble solids/acidity ratio. The wines were evaluated for density, alcohol content; total, volatile and fixed acidity; pH, dry extract, reducing sugars, reduced dry extract, alcohol in weight/reduced dry extract; free and total sulfur dioxide; anthocyanins,... |
