“…Preharvest 1-MCP treatment did not affect flesh firmness and starch pattern index values (SPIs) of 'Law Rome' apples (McArtney et al, 2009), but it did reduce internal ethylene concentrations (IECs), chlorophyll content (in terms of I AD values), and starch hydrolysis of 'Gala' apples (Doerflinger et al, 2015a). Preharvest 1-MCP applications reduced the incidences of soft scald and soggy breakdown in 'Honeycrisp' apple (DeEll and Ehsani-Moghaddam, 2010) and superficial scald in 'Golden Delicious' apple (McArtney et al, 2008). Preharvest 1-MCP treatment had few effects on the watercore development of 'Delicious' apple (Elfving et al, 2007), but it delayed it in another study (Yuan and Li, 2008).…”

The effects of preharvest and postharvest treatments of 1-methylcyclopropene (1-MCP) in combination or alone on fruit quality and the incidence of physiological disorders during storage of ‘Fuji’ apples [Malus sylvestris (L.) Mill var. domestica (Borkh.) Mansf.] at 20 and 0.5 °C were investigated. Preharvest 1-MCP (Harvista) treatments were applied 4 or 10 days before harvest (DBH), and then fruit were either untreated or treated with 1-MCP (SmartFresh) postharvest. Fruit were stored at 20 °C for up to 4 weeks or at 0.5 °C for up to 36 weeks. At harvest, starch pattern indices and watercore incidence and severity were lower in fruit with preharvest 1-MCP treatment applied 10 DBH than in untreated fruit and in fruit treated 4 DBH. At 20 °C, the combination of preharvest and postharvest 1-MCP treatments reduced the internal ethylene concentration (IEC) more than preharvest 1-MCP treatment alone, but not to a greater extent than postharvest 1-MCP treatment alone. Greasiness and watercore were reduced more by the combination of preharvest and postharvest 1-MCP treatments than by either treatment alone. However, preharvest and postharvest 1-MCP treatments, in combination or alone, did not consistently affect flesh firmness, titratable acidity (TA), soluble solids concentration, color a* values, or incidences of flesh browning, core browning, and stem-end flesh browning. At 0.5 °C, the combination of preharvest and postharvest 1-MCP treatments inhibited IECs and maintained firmness and TA more than no treatment or preharvest 1-MCP treatment alone. However, there was a lesser extent of differences than there was with postharvest 1-MCP treatment alone. Incidences of physiological disorders were not consistently affected by the preharvest and postharvest 1-MCP treatments. Overall, the results suggested that the preharvest 1-MCP treatment positively affected fruit quality attributes compared with no treatment during shelf life and long-term cold storage, but not as effectively as a combination of preharvest and postharvest 1-MCP treatments.

“…7, the production of 6-methyl-5-hepten-2-one was enhanced in more mature 'Honeycrisp' apples as a result of fruit ripening. Considering the feasibility of in vivo SPME to detect metabolic alterations caused by fruit ripening, the technique could be useful in precociously identifying metabolic changes associated with development of scald disorders, such as soft scald in 'Honeycrisp' apples prior to the visual onset of the disorder 48 .…”

An in vivo direct-immersion SpMe sampling coupled to comprehensive two-dimensional gas chromatography -time-of-flight mass spectrometry (GCxGC-ToFMS) was employed to capture realtime changes in the metabolome of 'Honeycrisp' apples during ripening on the tree. this novel sampling approach was successful in acquiring a broad metabolic fingerprint, capturing unique metabolites and detecting changes in metabolic profiles associated with fruit maturation. Several metabolites and chemical classes, including volatile esters, phenylpropanoid metabolites, 1-octen-3-ol, hexanal, and (2E,4E)-2,4-hexadienal were found to be up-regulated in response to fruit maturation. For the first time, Amaryllidaceae alkaloids, metabolites with important biological activities, including anticancer, anti-viral, anti-parasitic, and acetylcholinesterase (Ache) inhibitory activity, were detected in apples. considering the elimination of oxidative degradation mechanisms that adversely impact the representativeness of metabolome obtained ex vivo, and further evidence that lipoxygenase (LoX) pathway contributes to volatile production in intact fruit, in vivo Di-SpMe represents an attractive approach for global plant metabolite studies.In food analysis, there is increasing interest in the implementation of metabolomics approaches to understand complex biological networks that control production of high-quality food commodities and crop plants, from both health-and safety-related aspects. In metabolomics applications, great care should be expended when selecting sample preparation and extraction methods for a given application, as the employed methods play a large role in determining metabolome coverage, and subsequently, the quality of the attained data 1 . In this regard, attainment of comprehensive metabolite coverage necessitates implementation of non-selective and unbiased sample preparation and extraction methods. Further, as an essential component of such methods, metabolomics sampling and sample preparation protocols must incorporate a suitable metabolism-quenching step to terminate enzymatic activity, prevent enzyme-mediated metabolite conversions, and eliminate chemical breakdown of labile metabolites. Metabolism quenching of plant tissues is traditionally carried out by methods such as freezing with liquid nitrogen, freeze-drying, and addition of alcohol or acid 2 . However, implementation of these traditional methods may result in alterations to the metabolomic profile due a multiplicity of factors, such as metabolite decompositions and interconversions, losses of volatile metabolites, emission of touch-or wound-induced metabolites, and non-reversible losses of metabolites by absorption to cell walls and membranes 3-6 . Hence, it becomes questionable whether the metabolome captured under such circumstances is a true signature of the biochemical activity of the investigated system.Given the importance of apples as a valuable food crop with high worldwide demand, several studies have taken as focus the profiling of volatile metabolites ...

“…Fruit quality analyses. Fruit quality attributes were evaluated at harvest and after 3 to 4 months in storage using the same protocol described by DeEll and Ehsani-Moghaddam (2010). The optimum harvest time for each site was estimated by fruit color, a change of background color from green to yellow, and starch index between 5 and 7, as determined by the Cornell Starch Chart (Blanpied and Silsby, 1992).…”

‘Honeycrisp’ is a relatively new apple cultivar highly susceptible to physiological disorders, such as soggy breakdown. The overall objective of this study was to identify preharvest weather parameters that influence the incidence of soggy breakdown over the different phases of fruit development. Using weather data and evaluation of fruit quality from three sites in Ontario, two sites in Quebec, and one site in Nova Scotia from 2009 to 2011, and data from four sites in Ontario from 2002 to 2006, a model for soggy breakdown incidence (SBI) was developed to predict the level of susceptibility in ‘Honeycrisp’ apples. This model uses primarily two weather variables during the last phase of fruit development [91 days from full bloom (DFB) to harvest] to accumulate an SBI index during the growing season, from full bloom to harvest. Cool (temperature <5 °C) and wet conditions (precipitation >0.5 mm) during this last phase resulted in increased soggy breakdown susceptibility levels. The predictions of the SBI model resulted in 68% of well-estimated cases (threshold of ±5%) (RMSE = 6.45, EF = 0.28, E = −0.04). Furthermore, firmness was linked to soggy breakdown, in addition to weather conditions, revealing a positive effect of high firmness at harvest on the development of the disorder. However, the effect of fruit quality attributes (e.g., internal ethylene concentration, starch index, firmness, and soluble solid content) by themselves, without considering weather conditions, revealed no relationship with the incidence of soggy breakdown.
