“…'Isabel' grapes treated postharvest with CaCl 2 under ambient and modified atmospheres showed reduced fresh weight loss . However, the postharvest efficacy in maintaining fruit firmness seems to be higher when the use of CaCl 2 is combined with other bioregulators, such as 1-MCP, associated with hydrothermal treatment, as reported for guavas (CRUZ et al, 2015).…”

“…The pre-harvesting use of CaCl 2 also led to the reduction of mass loss during storage of 'Venus' grapes (DANNER et al, 2009) and provided apples with greater firmness, especially when combined with postharvest hydrothermal treatment (SHARMA et al, 2013). In plums, treated with CaCl 2 associated with other bioactivators, Manganaris et al (2008) reported both the reduction in weight loss and retention in firmness during storage in plums, providing a higher resistance to fruits in postharvest.…”

“…The SS were kept higher in clusters kept under ambient atmosphere, probably due to greater weight loss. Thus, postharvest SS increase was more related to the increase in the concentration of soluble compounds due to the loss of moisture during storage (DANNER et al, 2009). For banana, the treatment with an natural analogue of salicylic acid increased the decease resistance and delayed ripening, resulting in lower soluble solids (ZHU et al, 2016).…”

“…In this context, several techniques have been applied in postharvest grape storage, such as the use of refrigeration and modified atmosphere associated with the application of calcium chloride (DANNER et al, 2009;SILVA et al, 2012), also applied pre-harvest (RUIZ-GARCÍA et al, 2012;PORTU et al, 2015) as well as the association of pre-and postharvest treatments in other fruits, such as apples (SHARMA et al, 2013) and plums (MANGANARIS et al, 2008), aiming to promote an increase in fruit postharvest life, thus resulting in increased prospects of greater profitability.…”

“…The application of calcium chloride, either during the development of cluster of grapes or in postharvest, in order to increase the postharvest life, has conferred greater resistance to handling, reducing the loss of mass, decay and berries abscission (TECCHIO et al, 2009;SILVA et al, 2012), the incidence of disease (DANNER et al, 2009;DEVI;KUMARI, 2015) and promoting a decrease in the activity of polyphenoloxidase and the consequent browning of the raquis during storage (DANNER et al, 2009). …”

The high rate of fruit decay and berry drop reduces quality and increases postharvest losses in 'Isabel' grapes, requiring pre-harvest and postharvest management practices available to the small-scale farmer, which maintain quality and extend postharvest life of the clusters. The objective of this study was to evaluate the effect of the pre-harvest application of CaCl 2 and Citrus Biomass-based elicitor in 'Isabel' grapes, in the maintenance of quality during storage at room conditions under ambient and modified atmospheres. The experiment was conducted in a randomized block design with 8 replicates, in the field located at the municipality of São Vicente Férrer-PE, Brazil. 'Isabel' vines were treated 28 days before harvest with: Citrus Biomass-based elicitor (CB), Citrus Biomass-based elicitor + CaCl 2 (CB + C), CaCl 2 (C) and Control (T) -without application. Grapes harvested in the commercial maturity were stored in a 4 × 2 × 7 factorial arrangement, with 4 treatments (applied in the field), 2 storage conditions, ambient (AA) and modified (AM) atmospheres, under room conditions (25 ± 2 °C and 75 ± 2% RH) and 7 evaluation periods in four replicates. The application of CaCl 2 and CB-based elicitor reduced the berry drop index (55 and 75%, respectively), the decay and weight loss of 'Isabel' grape clusters. These treatments, associated or not, increased MA efficiency in maintaining cluster quality. The 'Isabel' grape berry drop index was directly influenced by the SS/TA ratio, pH and fruit decay index.

ResumoO alto índice de degrana e podridão das bagas reduzem a qualidade e elevam as perdas pós-colheita em uvas 'Isabel', demandando técnicas de manejo na pré e pós-colheita acessíveis ao pequeno produtor, que mantenham a qualidade e ampliem a vida útil pós-colheita dos cachos. Assim, este trabalho teve por objetivo avaliar o efeito da aplicação na pré-colheita de CaCl 2 e elicitor à base de biomassa cítrica em uvas 'Isabel' na manutenção da qualidade durante o armazenamento na condição ambiente sob atmosferas ambiente e modificada. O experimento foi conduzido em blocos casualizados a campo, no município de São Vicente Férrer-PE com 8 repetições. Videiras 'Isabel' foram tratadas, 28 dias antes da
