Postharvest ethylene production and ACC levels were determined in netted muskmelon fruits (Cucumis melo L. var. reticulatus `Magnum 45') exposed to temperature extremes by heating for 3 hr at 45C and/or storage at 4C. The possibility of using seal-packaging to protect the fruit against temperature-induced changes in ethylene production was examined by wrapping melons before treatment with a high-density polyethylene (HDPE) shrink-film. Ethylene production measured in fruit immediately after heating or removal from refrigeration was only 30% of the level determined before treatment, and continued to decline during refrigerated storage. However, the concentration of ACC in these same tissues remained constant or even increased slightly during storage. Wrapping fruit in HDPE film had no effect on the tissue concentrations of ACC or capacity for ethylene synthesis. In contrast to initial measurements, heated or refrigerated fruit held at room temperature (25C) for 24 hr produced ethylene at rates that equalled or exceeded the levels for freshly harvested fruit. These results strongly suggest that temperature-imposed restrictions on ethylene synthesis by netted muskmelon fruit are reversible and occur at the step responsible for converting ACC to ethylene via EFE rather than in the synthesis of ACC. Chemical names used: 1-aminocyclopropane-1-carboxylic acid (ACC).

Days After Anthesis

When tomato fruits of cv. Rtugers (normal), and of the rin and nor mutants were detached 10 days after anthesis (24% of the total growth period), they usually developed a characteristic swelling of one or more locules, which eventually developed a red, yellow or yellow-orange colour typical of the mature fruits of each strain. The remainder of the fruit tissues lost chlorophyll and eventually became necrotic. Ethylene treatment (25 �l/l) started 2 h after harvest advanced the onset of swelling in 10-day fruits of all strains. Treatment that was started 7 days after harvest had no effect on the onset of swelling in Rutgers and rin and had only a small effect on nor fruits. When ethylene was applied before first visible swelling (FS), the undeveloped portions of the fruits rapidly became necrotic and this necrosis spread to the swollen locules before they coloured. From FS and onwards, ethylene increased the rate of swelling and advanced colouring of the swollen locules. In some treated rin fruits, the swollen locules became intensely pink or red. Propylene treatment (500 �l/l) started 2 h after harvest also advanced the onset of swelling and red colour development in swollen locules in Rutgers fruits, as well as advancing the onset of the respiratory climacteric and the associated rise in ethylene production. Swelling in both control and propylene-treated fruits was not associated with any marked changes in respiration and ethylene production.

Induced Changes

An investigation of the changes in chloroplast ultrastructure induced by rust infection of cowpea leaves revealed that although initial changes in the pustule center resembled those observed in naturally senescing leaves, subsequent changes more closely resembled chromoplast development in certain ripening fruit. Ethylene treatment of healthy leaves induced changes similar to those seen during the later stages of pathogenesis and detached infected leaves released greater amounts of this gas than controls. The restriction of the chromoplast-like changes to the pustule center and the fact that the endogenous ethylene levels of newly picked infected leaves were barely higher than those of comparable healthy tissue suggested that most of the increased production of this gas was associated with the relatively small region of high fungal concentration. In contrast, naturally senescing leaves contained one-sixth, or less, of the ethylene content of infected leaves and released about half as much as infected tissue when detached. Thus it is suggested that, in many plants, increased ethylene production results in chromoplast-like development of the chloroplasts and that the degree of such development during pathogenesis or senescence may reflect the degree of ethylene production during these processes.

The present work evaluated the influence of calcium silicate on the polygalacturonase enzyme activity, respiration, ethylene, and the physicochemical characteristics on the post-harvest quality of two tomato hybrids. The experimental design was of randomized blocks, with four repetitions in protected cultivation environment. The treatments were distributed in a 2 x 5 factorial scheme, corresponding to the hybrids (Ivety and Natalia) and five doses of calcium silicate (0, 150, 300, 450 and 600 kg ha-1), which were applied on the same day as the pots were filled. Evaluations were carried out on the fruits, namely: ethylene production, fruit respiration, firmness, number of loculus, polygalacturonase activity, total carotenoids, lycopene, phenolic compounds, soluble solids content, pH, titratable acidity and ascorbic acid content.  The application of calcium silicate provided the reduction of ethylene production and fruit respiration. Natalia hybrid showed low polygalacturonase activity, this difference being due to genetic variabilityThe increase of calcium silicate doses provided the reduction of polygalacturonase enzyme concentration due to its constitution in the cell wall. The concentrations of lycopene, phenolic compounds, soluble solids, pH, titratable acidity and ascorbic acid in the fruits increased in response to the increasing doses of calcium silicate for 'Ivety'. Hybrids present distinct behaviors on the influence of the fertilization of tomatoes with calcium silicate, which can increase the post-harvest conservation and improve the physical-chemical characteristics of tomato fruits.

Life Prolongation

In recent years, consumers have shown interest in the ornamental use of some fruits that were previously used mainly for food purposes. However, the use of ‘mini-pumpkins’ for ornamentation can be limited by post-harvest aspects, such as skin depigmentation, fresh mass losses, ethylene production and respiration, which compromise the visual quality of the product, resulting in the loss of its ornamental value. The objective was to evaluate the effect of films application (control, carnauba wax, cassava starch and corn starch) in post-harvest of ornamental mini-pumpkins, aiming the shelf life prolongation (experiment 1) and reduction of ethylene production and respiration (experiment 2). The results obtained in experiment 1 pointed to lower mass loss and maintenance of the ornamental mini-pumpkins epidermis color with the application of carnauba wax film. In experiment 2, the application of carnauba wax and the ethylene action inhibitor (1-MCP) did not and respiration production of mini-pumpkins, suggesting that ethylene is not involved in the modifications that occur in the product during the time of exposure to the environment.

Red pepper fruit (Capsicum annuum L. cv Setubal) were treated with air (control) or 900 ppb 1-methylcyclopropene (1-MCP) for 24 h at 20°C. The fruit were packed in perforated polypropylene and stored for 4.5 days at 8°C (storage), 3 days at 20°C (simulated retail display), and 4.5 days in domestic refrigerator at 5.6°C. Fruit stored continuously at 20°C served as reference of respiration rate and ethylene production. The fruit quality, storage disorders, and physiological behavior in this simplified post-harvest handling chain and the possible effects of the CO2 accumulated during 1-MCP treatments were particularly studied. The critical points of the simulated post-harvest chain as regards fruit quality were the retail display stage at 20°C, the inhibition of ethylene as a side effect of 1-MCP, and, to a lesser extent the domestic refrigeration phase. Simulated retail display exacerbated shriveling and weight loss, and negatively affected aroma, finger texture and, to a lesser extent, fruit taste, and mouth texture. The 3% increase in the CO2 accumulated in both treatments resulted in a transient increase in the respiration rate, flesh and juice hue angle, glutamic and ascorbic acids; an increase in succinic acid (higher in 1-MCP treated fruit), and a transient decrease in citric acid, juice lightness and chroma. Compared with the control, the 1-MCP prevented the increase in skin chroma during the storage phase, the upsurge of ethylene production during the retail display phase, and doubled the fumaric acid levels in the refrigerator phase. 1-MCP may have increased the fruit susceptibility to shriveling and weight loss and, to a greater extent, pitting and gray mold rot in the domestic refrigerator. In brief, 1-MCP cannot be recommended for extending non-climacteric pepper shelf-life.

AbstractNatural weight losses, flesh and core browning, senescent breakdown and fruit rot, ethylene-production, firmness, soluble solids content, titratable acidity and taste of apple ‘Reinette Simirenko’ during storage, depending on the dose of postharvest treatment with 1-methylcyclopropene (1-MCP) were studied. Fruits were collected in harvesting maturity and treated with 1-MCP at the recommended dose of 1000 ppb (SmartFreshTM 0.068 g·m−3) and experimental doses of 750 ppb (75% of the recommended dose) and 500 ppb (50%). Apples were stored at 2 ± 1 °C and air humidity 85–90%. After seven months of cold storage, irrespective of dose of 1-MCP, on the 20th day of shelf-life, ethylene production from the treated apples was 3.9–5.3 times lower than that of the untreated ones. During the seven months of storage, fruits with post-harvest treatment had high firmness – 8.8–9.0 kg without a significant difference in range of 500–1000 ppb 1-MCP. 1-MCP treatment provides 0.6–1.0% higher content of soluble solids (highest level is for the treatment of 750 and 1000 ppb). Content of titratable acidity was higher by 1.4–1.7 times (the highest acidity was at 1000 ppb and, respectively, 1.1 and 1.2 times lower when treated with doses of 750 and 500 ppb). There was no skin browning and senescent breakdown and no flesh browning at 750 and 1000 ppb, and no fruit rot at 1000 ppb. When smaller doses (as recommended) are applied, a more harmonious taste of apples without reducing storage ability is achieved.
