“…Likewise, the respiration rate ranged from 0.015 to 0.026 mg CO 2 kg −1 h −1 with no significant differences between genotypes or environmental/irrigation conditions (Table S1). In general, both respiration rates and ethylene production have been poorly studied in LSL landraces [9], yet our results confirm the expected lower values in the Penjar tomato [28] than in commercial standard cultivars [43][44][45]. Although the ripening mutation responsible for the LSL phenotype was not confirmed in the genotypes evaluated in this study, most of the Penjar tomatoes bear the alc mutation affecting the NOR gene belonging to the NAC transcription factor family [14,28] and resulting in lower ethylene production rates accompanying extended fruit shelf life.…”

The diversity preserved within the European long shelf life tomato landraces (LSL) is a unique source to design high quality tomato products better adapted to changing environmental conditions and, thereby, to reduce food losses. The adaptation of LSL to water deficit (WD) management practices and their postharvest keeping ability can be used as tools to concomitantly enhance fruit quality and sustainable production. In this study, we investigated the effect of WD conditions and the plant growing environment (open field vs. tunnel) on quality traits of two genotypes of the Penjar LSL variety (modern hybrid (MV) and landrace (LR)). Changes in ripening-related quality traits (fruit ethylene production, respiration rate, firmness, color, soluble solids content, titratable acidity and the content of antioxidants, as well as specific sugars and acids) in response to the different preharvest factors were evaluated at the time of harvest and after a short period of storage (30 days), following actual commercial practices. Significant differences among genotypes were encountered for most quality traits at the time of harvest and higher intra- and inter-environment heterogeneity was observed in the LR than in the MV genotype. In general, Penjar tomatoes exhibit a low physiological activity (ethylene production, 0.56–1.33 µL kg−1 h−1, respiration rate: 0.015–0.026 mg CO2 kg−1 h−1) at harvest. In both genotypes, WD increased to a different extent the fruit external color (redness, lightness) as well as the sensory (SSC) and nutritional (antioxidant capacity) fruit profiles. By contrast, the growing environment had little impact on most fruit quality traits. Postharvest storage only led to a slight reduction in the fruit respiration and ethylene production, lower sugars and acids content, enhanced color and no firmness changes. Overall, the results from this study demonstrate that selecting the appropriate genotypes is the most important step towards the design of high-quality LSL tomatoes, while WD and short-term storage can be used by farmers as a strategy to differentiate the product quality in specific market niches.

“…After harvest, fruit were directly transported within 30 min in an air-conditioned car to the postharvest laboratory of Kangwon National University. Immediately after arrival, the fruit were washed, wiped and air-dried for 4 h as described by [22], and a further careful selection of fruit was made in the laboratory using a color chart [23] to ensure uniform maturity of the sample fruit within each color group. Pink stage means the fruit surface was 30-60% pink or red and red stage means more than 90% of the fruit surface was red [23].…”

“…The sealed cherry tomato fruit were removed from their package allowing air circulation for 1 h. Sample fruit were then placed in an airtight 1 L container. After a 3 h incubation as described by [22], a 1 mL gas sample was taken from each container using a gas tight syringe and injected into a GC-2010 Shimadzu gas chromatograph (Shimadzu Corporation, Tokyo, Japan). Ethylene, acetaldehyde and ethanol concentration were measured using a BP 20 wax column (30 m × 0.25 mm × 0.25 µm, SGE Analytical Science, Melbourne, Australia) and a flame ionization detector (FID).…”

Cherry tomato is a perishable fruit due to its high rate of ethylene production and respiration during ripening. 1-Methylcyclopropene (1-MCP) is known to control ripening and reduce decay of fruit by inhibiting ethylene action. In the present study, the influence of 1-MCP application on quality and storability of ‘Unicorn’ cherry tomato was observed. Fruit at pink and red maturity stages were put in the commercial plastic containers and sealed with 40 μm low density polyethylene (LDPE) film, treated with 1-MCP (0 µL L−1 (control), 0.035 µL L−1 and 0.1 µL L−1), and stored at 10 °C in 85 ± 5% relative humidity (RH). The results indicated that application of 1-MCP at 0.1 µL L−1 significantly affected firmness, cell wall thickness, water soluble pectin, weight loss, surface color, lycopene content and physiological parameters in both pink and red maturity stages compared to 0.035 µL L−1 and control. 1-MCP treatment at 0.1 µL L−1 kept the fruits firmer than 0.035 µL L−1 and the control throughout the storage period for both maturity stages. Cell wall degradation in the control treatment was higher compared to the 0.1 µL L−1 1-MCP treated fruits in both maturity stages throughout the storage period. Results of this study revealed the effectiveness of application of 0.1 µL L−1 1-MCP on quality and shelf life of cherry tomato.

“…Respiration rate of the melon fruits was measured as a function of CO 2 concentration using the closed system method (Tilahun et al, 2018). The melon fruits were sealed in a 4.65 L airtight containers and allowed to stand at each ripening temperature for 3 h, then analyzed using a CO 2 / O 2 analyzer (CheckMate 9900, PBI Dansensor, Denmark) and measurements expressed as mL CO 2 /kg•h -1 .…”

This study was conducted to identify the effect of ripening conditions on quality of 'Honey One' and 'Earl`s Talent' muskmelon cultivars stored at 10°C with 80 ± 5% relative humidity (RH) and room temperature (RT; 25°C) with 50 ± 5% RH. Weight loss and respiration rate of both cultivars were lower at 10°C than at RT throughout the ripening period. In the case of ethylene and ethanol production, 'Honey One' showed higher production than 'Earl`s Talent'. There was no significant difference in acetaldehyde production between the two cultivars. 'Honey One' had higher total soluble solids (TSS) than 'Earl`s Talent' throughout the ripening period. 'Earl`s Talent' showed lower sucrose but higher glucose and fructose contents than 'Honey One'. Titratable acidity (TA) and firmness decreased in both cultivars during the ripening period. 'Earl`s Talent' maintained firmness longer than 'Honey One'. The polygalacturonase (PG) activity of 'Honey One' decreased starting from the 6th day of ripening, reaching 12.58 nmol•kg-1 •s-1 on day 9 and maintaining that level afterwards while at RT. By contrast, 'Earl`s Talent' maintained PG activity up to day 21. Both water soluble pectin (WSP) and ammonium soluble pectin (ASP) increased but hydrochloric acid soluble pectin (HSP) and sodium hydroxide soluble pectin (SSP) decreased as the ripening period proceeded. The Hunter`s L* value of the two cultivars showed a decreasing trend in the flesh regardless of the ripening temperature. The sensory evaluation scores for both cultivars were highest on day 15th at 10°C and on day 9th at RT. Overall, our results revealed that the best nutritional benefits of muskmelon were achieved on the 15th day of ripening at 10°C and on the 9th day of ripening at RT irrespective of cultivars.
