The marketing of organic citrus fruit has markedly increased during the last few years. However, these fruits are not treated with chemical fungicides and suffer from relatively high rates of decay. In this study, we examined the possible use of a new hot water brushing (HWB) treatment, to disinfect the fruits and reduce decay development during postharvest storage. Preliminary observations hav...

Acetic acid (AA) as a vapor at low concentrations was effective in preventing fruit decay by postharvest fungi. Fumigation with 2.7 or 5.4 mg AA/liter in air at 2 and 20C reduced germination of Botrytis cinerea Pers. and Penicillium expansum Link conidia to zero after they had been dried on 0.5-cm square pieces of dialysis tubing. Decay of ‘Golden Delicious’, ‘Red Delicious’, and ‘Spartan’ appl...

In discussion related to the planning of the present workshop on 'disease resistance in fruit', the question arose as to whether fruit harvested from stressed plants have increased, decreased, or unchanged susceptibility to pathogens whose disease symptoms are expressed after harvest. For example, does preharvest water deficit stress affect the incidence and severity of stem-end rot (endophytic...

Climate/environment Rootstock/scion Planting design Pruning practices Pest management Irrigation Plant growth regulators Plant nutrition The goal for postharvest physiologists, whether they are working in basic or applied research, is to maximize the postharvest quality of horticultural commodities. Quality relates to several factors that can be commodity specific and mean different things to d...

Decline in postharvest losses of kiwifruit depended to maintain of quality characteristics during storage and transportation. Storage losses caused serious economic losses in kiwifruit. This study was conducted to inhibition of pathogen infection and increasing fruit quality of Kiwifruit. Hayward kiwifruits inoculated by B.cinerea conidia through pore wounds which formed by removal of the pedic...

To study the control of postharvest decay caused by Colletotrichum gloeosporioides and Penicillium expansum, gamma irradiation alone or in combination with fumigation was evaluated to extend the shelf life of apples in South Korea. An irradiation dose of 2.0 kGy resulted in the maximum inhibition of C. gloeosporioides and P. expansum spore germination. The gamma irradiation dose required to red...

The study involved an examination of the antifungal activity on red peppers of pullulan coating (P) and pullulan coating containing either water-ethanol (P + eEMF) or ethanol extract of meadowsweet flowers (P + eEMF). Pullulan was obtained from a culture of Aureobasidium pullulans B-1 mutant. Both non-inoculated peppers and those artificially inoculated with Rhizopus arrhizus were coated and in...

The aim of the study was to determine the antifungal effects of the essential oils against fungal pathogen Botrytis cinerea the causal agent of grey mould disease of peach (Prunus persica L.) under in vitro and in vivo conditions. Treatments consisted of four essential oils (anise, ammi, ziziphora and cinnamon) and five concentrations (0, 200, 400, 600 and 800 μL.L).Results of in vitro experime...

Postharvest green mold, caused by the pathogen Penicillium digitatum (Pers.:Fr.) Sacc., is the most economically important postharvest disease of citrus fruits in Spain, areas with Mediterranean climate, and citrus production areas worldwide characterized by low summer rainfall. Economic losses due to this disease have been typically reduced through the application of synthetic chemical fungici...
