Reports show that phytohormone abscisic acid (ABA) is involved in reducing zucchini postharvest chilling injury. During the storage of harvested fruit at low temperatures, injury symptoms were associated with cell damage through production reactive oxygen species. In this work, we have studied importance different non-enzymatic antioxidants on tolerance to cold stress treated ABA. The application ABA increases antioxidant capacity during accumulation ascorbate, carotenoids and polyphenolic...
The use of edible coatings has surged as a response to the ever-increasing demand for ecologically-friendly methods maintaining fruit quality during storage. This study analyses application different polysaccharide-based coatings, carboxymethylcellulose, chitosan, dextrin and starch, plasticizer agent, glycerol, with shown be most effective in postharvest zucchini cold Subsequently, improve these results, nutraceutical additives oleuropein olive oil, were tested combination dextrin. Results...
Ensuring food security is one of the main challenges related to a growing global population under climate change conditions. The increasing soil salinity levels, drought, heatwaves, and late chilling severely threaten crops often co-occur in field This work aims provide deeper insight into impact single vs. combined abiotic stresses at growth, biochemical photosynthetic levels Arabidopsis thaliana (L.). Reduced QY max was recorded salinity-stressed plants, NPQ increased heat stresses, qP...
Chilling injury is a physiological disorder that appears when zucchini fruit stored at low temperatures, causing severe diminution of the quality and nutraceutical value. Abscisic acid (ABA) has been proven to be key natural agent preventing low-temperature damage. This work aimed elucidate changes in exocarp metabolites during cold storage mechanisms underlying protective effects ABA through an untargeted metabolomics approach. A time-dependent metabolic modulation could observed response...
Abscisic acid (ABA) plays an important role in the regulation of several stress responses such as drought, high salinity and low temperature being also proved a key phytohormone for acquisition postharvest cold tolerance zucchini fruit. Therefore, it would be great interest to unravel mechanisms implicated ABA response, using metabolomic approach. The aim this work has been use combination tools identify main metabolic pathways involved ABA-mediated chilling As result study, was found that...
Cuticle composition is an important economic trait in agriculture, as it the first protective barrier of plant against environmental conditions. The main goal this work was to study role cuticular wax maintaining postharvest quality zucchini fruit, by comparing two commercial varieties with contrasting behavior low temperatures; cold-tolerant variety ‘Natura’, and cold-sensitive ‘Sinatra’, well ‘Sinatra’ fruit induced-chilling tolerance through a preconditioning treatment (15°C for 48 h)....
Abstract Salinity stress is one of the major abiotic factors limiting sustainable agriculture. Halotolerant plant growth‐promoting bacteria (PGPB) increased salt tolerance in plants, but mechanisms underlying are poorly understood. This study investigated PGP activity four halotolerant under salinity and tomato salt‐tolerance induced by synergy these with exopolysaccharide (EPS) mauran. All PGPB tested this were able to offer a significant improvement biomass stress; Peribacillus...
The storage of zucchini fruit at low temperatures during postharvest induces a physiological disorder called chilling injury that drastically reduces quality and shelf life. phytohormone abscisic acid (ABA) is involved in the acquisition cold tolerance fruit, being riboflavin pathway one most differentially induced with ABA treatment. Thus, aim this work was to elucidate involvement maintenance storage. After testing different concentrations exogenous riboflavin, 0.5 mM showed best results....

By studying stresses, stress interactions synergic effects have been highlighted....
Abstract The worldwide cultivated Cucurbita pepo L. is one of the most diverse species in plant kingdom. In this study, chilling tolerance over a wide range cultivars was characterized to discover allelic variants improving postharvest quality immature fruit during cold storage. For purpose, fruits from 126 accessions origin have been evaluated for weight loss and injury after 3, 7 14 days storage, classifying them into tolerant, partially sensitive accessions. To verify classification,...
