| Eighteen seedless grape genotypes differing in ripening season (early, mid and late) and in seed trace size (small, medium and large) were harvested at 6, 10, 14, 18 and 22 weeks past bloom (wpb). Using embryo rescue techniques it was studied if embryo do abort as the fruit matures and what percent embryos remain viable at later stages. The size of seed trace was also investigated to determine its influence on embryo viability during maturation. It was found that genotype have great influence on embryo culture traits. Late maturing genotypes showed fewer rescued embryos, germinated embryos and transplantable plants than early and mid season ones. The best culture time for grape embryo rescue is 6 and 10 wpb. At these dates, the largest number of embryos,... |

| ABSTRACT ‘BRS Vitoria’ is the most important Brazilian table grape cultivar in the domestic and foreign markets, standing out for the seedleness, pleasant flavor, high yield and mildew resistance. The aim of the present study was to determine the effect of the rootstock on the yield, production components, vigor, and physical and chemical characteristics of the ‘BRS Vitória’ grape under irrigation in the Brazilian semi-arid region. The experiment was conducted over eight consecutive production cycles in the period from 2015 to 2018 in a commercial area in the Senador Nilo Coelho project, Petrolina, PE. The treatments were represented by seven rootstocks: ‘IAC 572’, ‘IAC 766’, ‘IAC 313’, ‘Harmony’, ‘SO4’, ‘Paulsen 1103’, and ‘Freedom’, using a randomized... |

| ABSTRACT Seedless table grapes cultivars have been studied in the Sub-middle region of São Francisco Valley at northeast Brazil. For that region, it is important to identify cultivars with productive potential, better quality and efficiency, minimizing the expenses in terms of inputs and workforce, when compared to traditional cultivars. Specifically, the objective of this study was to determine the influence of different rootstocks on the quality and on the antioxidant potential of BRS Clara and Arizul table grapes cultivars of two production cycles. The experimental area belongs to the Experimental Field of Bebedouro/Embrapa Semiárido, located in the sub-middle region of São Francisco Valley, in Petrolina - PE, northeast Brazil. Both BRS Clara and Arizul... |

| O objetivo do presente trabalho foi avaliar a influência de diferentes porta-enxertos sobre a produção e características do fruto nas cultivares Thompson Seedless, Sugraone, Catalunha, Crimson Seedless, Marroo Seedless e Fantasy Seedless nas condições do Submédio do Vale do São Francisco. Foram realizados três experimentos, sendo um no Campo Experimental de Bebedouro, da Embrapa Semiárido, em Petrolina, PE e os demais em um vinhedo comercial no Município de Sento Sé, BA. No experimento 1, foram avaliadas três cultivares copa Thompson Seedless, Catalunha e Sugraone sobre cinco portaenxertos e uma testemunha não enxertada (pé-franco). Os portaenxertos foram Harmony, 420 A, IAC 766, Couderc 1613 e Paulsen 1103. No experimento 2, as cultivares copa foram... |
