  • Impact of training system on ‘Blanc Du Bois’ vegetative growth, yield
           components and fruit composition

    • Abstract: Viticulture Data Journal 2: e53118
      DOI : 10.3897/vdj.2.e53118
      Authors : Justin Scheiner, Juan Anciso, Fritz Westover : ‘Blanc Du Bois’ (Vitis spp.) is the most widely grown Pierce’s disease tolerant white grapevine cultivar in Texas. As an interspecific hybrid, its growth habit is seimi-drooping, and 'Blanc Du Bois' is characterized as vigorous. This study evaluated the impact of training system (Mid-Wire Cordon with VSP, Mid-Wire Cane with VSP and Smart-Dyson, High-Wire Quadralateral, and Watson) on 'Blanc Du Bois' growth, yield components, and fruit composition at two locations in Texas. The first site was located in the Rio Grande Valley where the mean extreme minimum winter temperature is -1.1 to 1.7° C (USDA Cold Hardiness Zone 10a). As a result of climate and site conditions, vine size, determined by dormant pruning weight, was very large averaging from 3.71 to 5.56 kg per vine across training systems over a three-year period. At this site, the horizontally divided systems, High-Wire Quadrilateral and Watson were the highest yielding averaging 10.66 and 7.49 kg per vine, respectively, as a result of more shoots per vine, and higher fruitfulness. The Mid-Wire Cordon and Mid-Wire Cane Pruned Training Systems had lower yields in two out of three years, but fruit maturity indices soluble solids and pH reflected more advanced maturity at harvest. At the second site, located in the Central Gulf Coast of Texas (USDA Cold Hardiness Zone 8b), vines were less vigorous with pruning weights averaging 1.66 to 1.83 kg per vine across training systems over three years. Consistent differences in yield components, vine size, and fruit composition were not observed, and all the three training systems under study had acceptable growth and fruiting characteristics. The results of this research suggest that 'Blanc Du Bois’ vigor potential and growth habit makes it well-suited for horizontally divided canopy training systems, particularly on vigorous sites.

  • Opening data and research objects in viticulture: The Viticulture Data
           Journal (VDJ)

    • Abstract: Viticulture Data Journal 1: e49717
      DOI : 10.3897/vdj.1.e49717
      Authors : Lyubomir Penev, Maritina Stavrakaki, Teodor Georgiev, Leonardo Candela, Stefano Poni, Robert Savé, Denis Rusjan, Katerina Biniari, Mario Pezzotti, Pascal Neveu, Pavel Stoev : The Viticulture Data Journal (VDJ) is launched with the aim of offering a publication venue for non-conventional but valuable outputs of the research cycle: data, models, methods, software, data analytics pipelines and visualisation methods in viticultural research. VDJ is published on the ARPHA journal platform, which supports the full life cycle of a manuscript, from writing through submission, peer review, publication and dissemination within a single online collaborative platform. During the AGINFRA+ project, which has supported the journal launch, ARPHA has been extended to be used from the AGINFRA+ Virtual Research Environment (VRE). HTML XML PDF
