‘Perfection’ apricot fruit (Prunus armeniaca L.) were treated with 1 ml l 1-methylcyclopropene (MCP) for 4 h at 20°C then stored at 0 or 20°C. The onset of ethylene production was delayed and respiration rate was reduced following MCP treatment. MCP treatment resulted in less firmness and titratable acidity loss during storage at both temperatures and delayed production of volatile alcohols and...

Fruit firmness and crispness are important traits of cucumber because they directly affect its commercial value. We performed quantitative trait locus (QTL) analysis these fruit texture with the double-digest restriction-site-associated DNA sequencing (ddRAD-Seq) technique detected 31 QTLs for firmness: 11 placenta firmness, 12 skin 8 flesh firmness; 25 crispness-related scores: 10 index, appar...

Fruit softening is an important part of the ripening process, and involves changes to cell turgor and primary cell wall structure. Most of the polysaccharide components of the cell wall are subjected to some degree of controlled degradation, resulting in a loosening and swelling of the wall structure, a weakening of cell wall strength, and reduced intercellular adhesion. Early ripening changes ...

Pectins are essential components of primary plant cell walls and middle lamellae, and are related to the consistency of the fruit and its textural changes during ripening. In fact, strawberries become soft as the middle lamellae of cortical parenchyma cells are extensively degraded during ripening, leading to the observed short post-harvest shelf life. Using a custom-made oligonucleotide-based ...

Peach [Prunus persica (L.) Bastch.] "cv. Flordaprince" fruits at commercial maturity were immersed in 0, 0.5, 1.0 and 1.5 mM salicylic acid (SA) solution for 10 min, stored at 0 ◦ C for 28 days, then moved to 20 ◦C for 3 days to simulate shelf life. Fruit weight losses, firmness, TSS, acidity, Vit.C, sugars, anthocyanin, total phenols and two enzymes namely peroxidase and polyphenol oxidase act...

Removal of astringency by endogenously formed acetaldehyde, achieved by postharvest anaerobic treatment, is of critical importance for many types of persimmon fruit. Although an anaerobic environment accelerates de-astringency, it also has the deleterious effect of promoting excessive softening, reducing shelf life and marketability. Some hypoxia-responsive ethylene response factors (ERFs) part...
