| Abstract the aim of this study was to evaluate the chemical characteristics and sensory acceptance of juices and cuts of ‘Bordô’ and ‘Niágara Rosada’ grapes. The experimental design was in a one-factor scheme, with five levels. Treatments were: T1 – ‘Bordô’ (100%); T2 – ‘Bordô’ (70%) + ‘Niágara Rosada’ (30%); T3 – ‘Bordô’ (50%) + ‘Niágara Rosada’ (50%); T4 – ‘Bordô’ (30%) + ‘Niágara Rosada’ (70%); T5 – ‘Niágara Rosada’ (100%). Chemical analyses were: content of soluble solids, pH and titratable acidity, and sensory analyses were: color, aroma, flavor, body and global acceptance. For the soluble solids content, the highest averages were verified in T1, T2 and T3 treatments. As for pH, the highest value was recorded in T3, T4 and T5 treatments, while the... |

| Key message The transcriptomes of wild and cultivated grapes consists of similar expressed genes but distinct wiring of co-expressed modules associated with environmental conditions. Abstract Grapevine is an important fruit crop worldwide, with high economic value and widespread distribution. Commercial production is based on Vitis vinifera, and, to a lesser extent, on hybrids with American grapes, such as V. labrusca. Wild grape relatives are important sources of resistance against biotic and abiotic factors; however, their global gene expression patterns remain poorly characterized. We associated genome-wide transcript profling to phenotypic analyses to investigate the responses of cultivated and wild vines to vineyard conditions. The expressed genes in... |

| Neste trabalho serão discutidas as influências de diferentes fatores fisiológicos e ambientais sobre o desenvolvimento e a produção da videira cultivada em áreas irrigadas do Nordeste Brasileiro. Entretanto, para que estes fatos sejam entendidos, tornam-se necessários o conhecimento de alguns aspectos do processo fotossintético, e, conseqüentemente, da produção de açucares solúveis e do amido, da distribuição dos produtos fotossintetizados, da fenologia e dos processos que levam a formação das gemas reprodutivas da videira. |

| Resumo: O objetivo deste trabalho foi avaliar os efeitos de viroses em videiras sintomáticas e assintomáticas sobre as variáveis agronômicas relacionadas ao vigor das plantas e à qualidade enológica da uva, e comparar os isolados virais obtidos nessas duas condições. Realizaram-se dois experimentos com quatro cultivares. Todas as plantas foram indexadas, por meio da reação em cadeia da polimerase via transcrição reversa (RT-PCR) em tempo real, quanto à provável ocorrência dos seguintes vírus: Grapevine virus A (GVA), Grapevine virus B (GVB), Grapevine virus D (GVD), Grapevine leafroll-associated virus (GLRaV-1 ao -4, GLRaV-4 estirpe 5), Grapevine rupestris stem pitting-associated virus (GRSPaV) e Grapevine fleck virus (GFkV). As variáveis avaliadas foram:... |

| Vineyard soils of the Campanha Gaúcha region of Rio Grande do Sul are sandy and have low to medium organic matter content, displaying low natural ability to supply nitrogen (N). Therefore, maintenance of cover crops is essential or the protection of the soil surface from the impact of raindrops and water erosion. The application of nitrogen fertilizers is also necessary. However, cover crops can absorb part of the nitrogen applied in the soil, decreasing the availability to young vines, which may slow the growth of root and shoot, and thus, the beginning of grape production. |

| The southernmost region of the state of Rio Grande do Sul, Brazil, has emerged as one of the major poles for fine grape production (Vitis vinifera) for wine processing. In this region, grapevine rust mite (Calepitrimerus vitis) is one of the major pests for the culture; however, information is lacking about production losses caused by this species and acaricides for its control. In this paper, the acaricide effect of azadarachtin, boron + nitrogen on orange peel oil, sulfur and spirodiclofen on C. vitis on Merlot cultivar commercial grapevine was evaluated and production losses caused by the presence of the mite were estimated. The experiment was conducted during the 2012/2013 and 2013/2014 growing seasons, comparing the infestation levels of C. vitis and... |

| Linepithema micans (Forel) (Hymenoptera: Formicidae) is the main ant species responsible for the spreading of Eurhizococcus brasiliensis (Wille) (Hemiptera: Margarodidae), a soil scale that damages grapevine plants in southern Brazil. The effect of contact and ingestion of insecticides on the control of L. micans was evaluated in a greenhouse using grapevines (Vitis spp.) infested by L. micans. The insecticides thiamethoxam (250, 187.5, and 125 g/ha), Þpronil (4, 5, and 50 ml/ha), and imidacloprid (650 g/ha) were sprayed on the ground, whereas toxic baits containing boric acid (0.5, 1.0, and 1.2%), pyriproxyfen (0.3 and 0.5%), and hydramethylnon (0.5%) were evaluated in different formulations. Hydramethylnon (toxic bait) and thiamethoxam (chemical barrier)... |

| Grapevines can host up to 86 virus species, some of which affect plant vigor, production and fruit quality (Fuchs, 2020). In 2014, a Vitis vinifera cv. Semillon vine showing yellow speckles and mild leafroll symptoms in Bento Gonçalves, RS, Brazil, was investigated for viruses (Silva et al., 2017), resulting in the detection of grapevine enamovirus 1, grapevine yellow speckle viroid 1 and hop stunt viroid. |

| In the regions with mild winters, usually the chilling requirements for bud dormancy release of grapevines are not fulfilled, and only the highly toxic products CaCN2 (calcium cyanamide) and H2CN2 (hydrogen cyanamide) are recommended in conventional viticulture for budbreak. The purpose of this study was to verify the effect of garlic extract on budbreak of 'Niagara Rosada' grapevines in two different vineyards. The highest dose of garlic extract (70mL L-1) showed a great potential for budbreak in organic production, presenting similar effects of cyanamides in budbreak. This treatment improved the sprouting percentage, number of clusters, accelerated the beginning of sprouting and reduced the cycle between pruning and harvest. |

| The Amplification Fragment Length Polymorphism (AFLP) technique was employed to study genetic variations which can be induced in vines by the stress occurring during different aspects of viticulture (in vitro cultivation, in vitro thermotherapy and virus infection). Analysis of AFLP banding patterns, generated by using 15 primer combinations, pointed to negligible genetic variation among plants exposed to individual stress. The average of similarity coefficients between differently stressed plants of the cultivars Müller Thurgau and Riesling were 0.984 and 0.991, respectively, as revealed by AFLP analysis. The low incidence of observed polymorphism demonstrates the high level of genome uniformity in plants reproduced by in vitro micropropagation via nodes,... |
