'BRS Isis' is a novel hybrid seedless table grape with large reddish bunches. This cultivar is cultivated in tropical and subtropical areas and has potential to be exported overseas; however, under these growth conditions, grapes can be severely damaged by gray mold (Botrytis cinerea), the main postharvest disease of table grapes. Thus, this study aimed to evaluate different pre-and postharvest strategies to extend the storage period of 'BRS Isis' seedless table grapes. The treatments consisted of grapes packed into carton boxes under cold storage (1 • C and high relative humidity), pre-and/or postharvest treatment with potassium bicarbonate or a biological control agent (Bacillus subtilis), all with Botrytis inoculation. Additionally, two controls, with and without Botrytis inoculation, were also evaluated. The experimental design was completely randomized with eight treatments and three replications, and each plot consisted of four bunches. After a 50-day cold storage period, the carton boxes were kept for five days at room temperature (22 • C). Gray mold incidence and water loss, as well as soluble solids (SS), pH, titratable acidity (TA), SS/TA ratio, and color attributes were evaluated during both periods. Cold storage effectively reduced gray mold in 'BRS Isis' seedless grape for a period of 50 days, even when grapes were inoculated; however, no difference among treatments was observed. Higher water loss was observed in both non-treated control treatments.

“…The need to increase productive sustainability and the pressure of consumers groups has forced the reevaluation of such models of conventional production (FADINI, LOUSADA, 2001). Following this concept, the use of plastic cover represents an alternative for grape production, especially in warm and Organic production of red wine grapes under plastic cover... humid climates, because this system could avoid the wetting of upper plant parts and, consequently, decrease pathogenic fungus, allowing the reduction or elimination of chemical fungicides (GENTA et al, 2010). Chavarria et al (2007) reported that during maturation of 'Moscato Gallo' grapes, there was a decrease of decay incidence between 57.6 and 84.5% due to plastic covers.…”

A trial was carried out aiming to evaluate the development and yield of red wine grapevines under plastic cover in an organic production system in Guarapuava, the Central-Southern region of Paraná State, Brazil. The experimental design was in a randomized blocks, in a 5x2 factorial arrangement (cultivars x rootstocks), with five red wine vine cultivars (Merlot, Malbec, Carbenet Sauvignon, Ives and Early Isabella) and two rootstocks (Paulsen 1103 e VR 043-43). The grafted grapevines were planted in September of 2005 and the evaluations carried out for the three first productive cycles (2006/2007, 2007/2008, 2008/2009). The following variables were evaluated: phenological growth stages, number of clusters, average cluster weight, total yield, total soluble solids content and fresh weight of pruning material. The cultivation of wine grapevines in an organic system under plastic cover demonstrated viability, inhibiting the incidence of diseases and reducing the needs of control. The most limiting factor was the damage caused by wasps and bees that decreased cluster harvest. Despite this problem, between tested grapevine cultivars, the Early Isabella was the most productive in all years, while Malbec was also outstanding in the first cycle. VR 043-43 hybrid could be a suitable rootstock for red wine production in areas infested by 'Perola da Terra' scale insects (Eurhizococcus brasiliensis).Index terms: Vitis spp., grapevines, 'VR 043-43', agroecology. RESUMOUm experimento foi conduzido com o objetivo de avaliar o desenvolvimento e produtividade de uvas para vinho tinto sob cobertura plástica, em sistema orgânico, em Guarapuava, região centro-sul do estado do Paraná, Brasil. O delineamento experimental foi em blocos casualizados, em esquema fatorial 5x2 (cultivares x porta-enxertos), com cinco cultivares de vinho tinto (Merlot, Malbec, Cabernet Sauvignon, Bordô e Isabel Precoce) e dois porta-enxertos (Paulsen 1103e VR 043-43). As videiras enxertadas foram plantadas em setembro de 2005 e as avaliações foram conduzidas nos três primeiros ciclos produtivos (2006/2007, 2007/2008, 2009/ 2009). Foram avaliadas as seguintes variáveis: estádios fenológicos, número de cachos, massa média dos cachos, produtividade, teor de sólidos solúveis totais e massa fresca do material de poda. O cultivo de videiras para vinificação em sistema orgânico sob cobertura plástica demonstrou ser viável, inibindo a incidência de doenças e reduzindo a necessidade de controle. O fator mais limitante foi o ataque de vespas e abelhas que severamente reduziram a colheita de cachos. Apesar desse problema, entre as cultivares de videira testadas, a Isabel Precoce foi a mais produtiva em todos os anos, enquanto a 'Malbec' foi também superior no primeiro ciclo. O híbrido 'VR 043-43' poderia ser um porta-enxerto adequado para a produção de uvas para vinho tinto em áreas infestadas com pérola-da-terra (Eurhizococcus brasiliensis).Termos para indexação: Vitis spp., videiras, VR 043-43, agroecologia.

“…Later, the use of plastic cover occurred in Paraná (Genta et al, 2010) and Sao Paulo (Lulu et al, 2005;Pedro Junior, 2006;Colombo et al, 2011). According with information of the Agricultural Cooperative of Juazeiro -BA (ACJ), the use of the plastic cover in the Sao Francisco River Valley region has been taking place since 2000, to protect the vineyards of rain and prevent the occurrence of cracks berries throughout the period of grape maturation and harvesting.…”

Data from field experiments conducted in table grape vineyards variety of Festival in Petrolina-PE in the period from September 19 to October 12, 2010 were used to evaluate the influence of plastic cover on microclimate conditions of vineyards in São Francisco River Valley region. Three treatments were studied: canopies without plastic cover (WC); with plastic cover positioned at 50 cm (PC50), and at 100 cm (PC100) above canopy. The results indicate that the plastic cover prevented the passage of about 40% of the global and net radiation, retained the relative humidity inside the canopy, generated an increase of air temperature and marked reduction in wind speed over the canopy of treatment PC50. However, treatment PC100 had a higher incidence of short wavelength and net radiation under canopy (on the berries) than WC and PC50 treatments, resulting in more favorable weather conditions, providing about 40% greater productivity in this treatment. Therefore, the vineyard with plastic cover placed at 100 cm above canopy represents a more suitable alternative to the climatic conditions of the region of the São Francisco River Valley.
