| Popis: | ABSTRACT ‘BRS Magna’ was released with the aim of improving the colour, sweetness, and flavour of Brazilian grape juice. Therefore, it is necessary to test this cultivar on different rootstocks in order to identify the canopy/rootstock combinations that best contribute to the purpose of the enterprise under cultivation conditions. Thus, the objective of this study was to evaluate the influence of different rootstocks on the yield components and physical characteristics of the bunch and berry of the ‘BRS Magna’ grapevine. The research was conducted in the vineyard established in the experimental area of the Universidade Tecnológica Federal do Paraná (UTFPR), located in the municipality of Pato Branco, Paraná. The ‘BRS Magna’ was grafted onto 10 rootstocks: ‘Kober 5BB’, ‘SO4’, ‘IAC 766 Campinas’, ‘Harmony’, ‘Paulsen 1103’, ‘420A’, ‘IAC 572 Jales’, ‘Freedom’, ‘IAC 313 Tropical’, and ‘101-14 MGT’. For three agricultural years, production, productivity, vegetative vigor, number of bunches, and average bunch weight per plant, length and width of bunch and berry, as well as average berry weight were evaluated. Analysis of variance showed a interaction between rootstocks and production years for all variables. ‘BRS Magna’ showed alternation in yield components, vegetative vigor and physical characteristics of bunch and berry between the evaluated crops. Under the cultivation conditions studied, the recommended rootstock for the ‘BRS Magna’ cultivar is ‘IAC 572 Jales’. On the other hand, ‘101-14 MGT’ and ‘420 A’ are not recommended as rootstock for this cultivar. |
