Natural Incidence

Potassium sorbate, a program of four fungicides, or one of three chitosan formulations were applied to clusters of ‘Thompson Seedless’ grape berries at berry set, pre-bunch closure, veraison, and 2 or 3 weeks before harvest. After storage at 2°C for 6 weeks, the natural incidence of postharvest gray mold was reduced by potassium sorbate, the fungicide program, or both together in a tank mixture, in 2009 and 2010. In 2011, the experiment was repeated with three chitosan products (OII-YS, Chito Plant, and Armour-Zen) added. Chitosan or fungicide treatments significantly reduced the natural incidence of postharvest gray mold among grape berries. Berries harvested from vines treated by two of the chitosan treatments or the fungicide program had fewer infections after inoculation with Botrytis cinerea conidia. None harmed berry quality and all increased endochitinase activity. Chitosan decreased berry hydrogen peroxide content. One of the chitosan formulations increased quercetin, myricetin, and resveratrol content of the berry skin. In another experiment, ‘Princess Seedless’ grape treated with one of several fungicides before 4 or 6 weeks of cold storage had less decay than the control. Fenhexamid was markedly superior to the other fungicides for control of both the incidence and spread of gray mold during storage.

The demand for high-quality nutritional products has increased fruit consumption, as grapes, for this reason postharvest techniques are required to prevent losses, to preserve quality, to extend shelf life, and to attend to consumer needs. In this way, the objective of this study was to evaluate strategies to control gray mold caused by Botrytis cinerea in ‘BRS Nubia’ grapes during cold storage and shelf life periods. Grape bunches were harvested from a commercial vineyard in Marialva, Parana, Brazil. Grapes were subjected to the following treatments: cold storage at 2 ºC (control), cold storage at 2 ºC with SO2-generating pads, cold storage at 2 ºC and inoculated with B. cinerea suspension, and cold storage at 2 ºC with SO2-generating pads and inoculated with B. cinerea suspension. The experiment was conducted in a complete randomized design with five replications per treatment using four bunches per experimental unit. A factorial arrangement (absence/presence of SO2 pads × absence/presence of Botrytis inoculation) was applied. At the end of 30 days of cold storage and 7 days of shelf life (22 ºC), gray mold incidence, shattered berries, and physicochemical parameters were evaluated. The gray mold incidence on ‘BRS Nubia’ grapes decreased when SO2-generating pads were used during cold storage. Berry weight loss was greater in the treatments without SO2-generating pads after 30 days of cold storage followed by 7 days of shelf life. Berry firmness, soluble solids content (SS), total acidity (TA), SS/TA ratio, and anthocyanins concentration were not negatively affected by SO2-generating pad treatments. However, a slight increase in the shattered berries percentage was recorded for the SO2-generating pad treatments. No significant quality loss of ‘BRS Nubia’ grape was evident after 30 days of cold storage followed by 7 days of exposure at room temperature. In this context, SO2-generating pads can be used to control the gray mold incidence on ‘BRS Nubia’ table grapes during cold storage.

The use of vented clamshells has become popular in the packaging of grapes for local and international markets. The aim of this study is to evaluate the postharvest preservation of ‘Benitaka’ table grapes individually packaged in vented clamshells using different types of SO2-generating pads and perforated plastic liners during cold storage. A completely randomized design with four replications in a two-factor arrangement with an additional treatment [(4 × 3) + 1] was used. The trials were carried out under two situations: Artificial or natural infections with Botrytis cinerea, which is the causal agent of gray mold on table grapes. The incidence of gray mold, shattered berries, and stem browning were evaluated at 30 and 45 days of cold storage at 1 ± 1 °C and 3 days of shelf-life at 22 ± 1 °C after the period of cold storage. Mass loss and berry firmness were also examined at the end of the cold storage period. The use of dual-release SO2-generating pads containing 5 or 8 g of a.i. and slow-release pads with 7 g of a.i. was effective in controlling the incidence of gray mold in grapes packaged in vented clamshells and kept under cold storage for up to 45 days. Under these storage conditions, perforated plastic liners with 0.3% ventilation area or micro-perforated liners with 1.0% ventilation area reduced the percentage of mass loss and shattered berries.

Vitis Labruscana

An active packaging film (APF1) with releasing low concentration sulfur dioxide (SO2) was tested on quality of ‘vitis labruscana kyoho’ table grape. All samples were stored at 5°C and during the storage period the main quality parameters, weight loss, berries shatter, decay, firmness, total soluble solids content (TSS), total acid (TA, using the PH of grape juice instead of the TA ), Vitamin c (Vc) content were monitored and compared with the control sample unpacked in any film. Results demonstrated that APF1 could reduce water loss of table grapes, prevent it from pathogens infection. The results also showed that APF1 could greatly guarantee a long shelf life for grape. After storage 56 days (storage at 0~5°C), the water loss, berry firmness, TA and Vc content in grapes packaged in APF1 were slowly reduced, TSS was slight increased, percentage of shatter and decayed berries of grapes were 22% and 27%, respectively. The percentage of berries decay of grapes packaged in APF1 was reduced to 5% from 21% for control batches on 11th days. All unpackaged table grapes (control batches) were decayed after 28 days. APF1 would help to preserve quality and extend shelf life of table grapes.
