Special Issue Information

Dear Colleagues,

Fruit after harvest is still characterized by living organism features. Many physiological processes occur in fruit, which provide the development of undesirable changes in physicochemical parameters, sensory attributes, nutritional value and biological activity, and also the growth of microorganisms, shortening the shelf life. Thus, to extend the availability of fresh fruit for customers, it is necessary to apply proper storage techniques but also investigate and explain the physiological changes in fruit. The Special Issue “Postharvest Physiology and Disease of Fruits” is dedicated to original research papers, reviews, opinions and short communications considering technological and biological research of harvested fruit. This includes the areas of physiology, biochemistry and microbiology of fruit, innovative techniques in extending the shelf life, postharvest biological activity and fruit diseases.

Pre- and Post-Harvest Infection of Pasteurized Pickles with Fungi and Their Pectinolytic Potential to Soften the Product

Fungi and their enzymes have long been thought to cause the softening of pasteurized gherkins; however, the exact fungal species and timing of contamination are unknown. Ready-to-sell pickle jars and blossoms of growing gherkins were inoculated with DNA-sequenced fungi isolated from rotting gherkins to cause softening at various stages of production. Ready-to-sell gherkins inoculated with Fusarium oxysporum, Fusarium equiseti, Galactomyces geotrichum, Mucor circinelloides, Mucor hiemalis, Mucor fragilis, Plectosphaerella cucumerina, Alternaria sp., and Cladosporium sp. indicated a measurable texture reduction after pasteurization and 6 months of storage at room temperature. No texture changes were observed in gherkins infected during the growth phase. The fungi M. hiemalis, M. fragilis, and G. geotrichum tolerated the acidic-saline (approx. pH 4) environment in the jar for several days, thus the pectinolytic enzymes of these candidates were tested for heat and pH resistance. Although the measured endo-Polygalacturonase (PG) of M. fragilis had its optimum activity at pH < 4, all fungal enzymes were inactivated within 3 min at 80 °C corresponding to the pasteurization heat. Our study shows that conventionally occurring fungi and their enzymes have the potential to induce softening in pickles. Softening by these fungi is unlikely due to post- or pre-harvest contamination without any other influences. Full article

Tomatoes (Solanum lycopersicum L.) are widely cultivated and consumed, but ripening should be carried out in controlled storage conditions to extend their shelf life and avoid economic losses. The aim of this study was to investigate the effects of visible artificial light on the ripening and quality of fresh market tomatoes stored at a low temperature and high humidity. The postharvest performance with respect to the ripening of organically grown tomatoes in the Toscano cultivar, with a long storage life, was studied in the presence and the absence of visible LED light. The maturation kinetics of the tomatoes was modeled using the Power Law equation. Results showed that tomatoes stored in the presence of light exhibited an increased respiration rate and a faster preclimacteric phase. Lycopene content, total soluble solids, and maturity index increased in the presence of light. Hence, light increased the postharvest ripening of tomatoes, affecting their shelf life. Full article

Phospholipase D (PLD) in plants plays an important role in growth, development, and stress response. The effect of hexanal on PLD in banana fruit responding to Colletotrichum musae infection remains poorly understood. In this study, four putative PLD genes, named as MaPLD1, MaPLD2, MaPLD3, and MaPLD4 were identified from banana fruit. The four MaPLDs can be classified into three of the seven known PLD families according to sequence characterization. Their deduced amino acid sequences displayed homology of PLDs from other plant species. Furthermore, the specific expression analysis of PLD genes in banana fruit in response to infection in C. musae was studied and the response relationship between PLD family members and banana fruit under anthracnose stress was clarified. Changes in both the activity of PLD and PLC, and the connection between hexanal and phospholipases in the banana fruit C. musae infection were compared. The results showed that the incidence of disease in banana inoculated with C. musae was dramatically increased after 6 days of storage, the activation of PLD and PLC in infected anthracnose fruit before disease development, and that this activation was inhibited by hexanal treatment, which suggested that both enzymes play a protective role in banana fruit to cope with C. musae infection and the participation of hexanal in their regulation. Of the four MaPLD genes, the anthracnose had a stronger effect on MaPLD1 and MaPLD4. These data demonstrated that hexanal treatment could enhance fruit disease resistance to C. musae, and that PLD could take part in the disease defensive system of harvested banana fruit to C. musae by modulating the metabolism of cell membrane lipids, and thus suppress disease development in C. musae -inoculated banana during storage.

Postharvest rot is a major issue in fruit. However, the cause of postharvest rot on R. sterilis fruit has not been clarified, and there are few studies on the disease control. In this study, the fungus causing postharvest rot is isolated from the symptomatic R. sterilis fruit, and identified by morphological characteristic, pathogenicity test and molecular identification. Moreover, the effects of methyl jasmonate (MeJA) or calcium chloride (CaCl2) alone and their combination on disease resistance to fruit rot were assessed by the determination of defense-related enzyme activity and other indicators. N. clavispora was identified as the main fungus causing the postharvest rot of R. sterilis fruit. The infected fruits were treated with MeJA and CaCl2, and these partially controlled the disease, were additive in effectiveness when used together, increased retention of vitamin C content and fruit firmness, and both enhanced and improved the retention of PAL, POD and PPO activities. The treatment of 500 μL/L MeJA and 3% CaCl2 resulted in the high inhibition of the disease. To our knowledge, this is the first report of N. clavispora causing R. sterilis fruit rot, and the combined treatment is a promising method for controlling postharvest rot on R. sterilis fruit.
