ABSTRACT: Methyl jasmonate (MeJA) is recognized as a plant hormone that induces several biochemical changes related to improving fruit quality, but it evident the effect of MeJA during postharvest very variable upon concentration, species, and even cultivars. The objective this research was relate application regulator at low concentration (10 µmol L-1 for 24 h) in physiology, on incidence anth...

Scape bending disorder is the most important factor affecting postharvest loss of gerbera cut flowers. One of the ultimate reasons for gerbera stem bending is lignin, with deformation structural functions and defensive mechanisms. This postharvest experiment was conducted to evaluate the role of phenylalanine ammonia lyase (PAL) and peroxidase (POD) enzymes activity in stem bending of two gerbe...

Postharvest pathogens can penetrate fruit by breaching the cuticle or directly through wounds, and they show disease symptoms only long after infection. During ripening and senescence, the fruit undergo physiological processes accompanied by a decline in antifungal compounds, which allows the pathogen to activate a mechanism of secretion of small effector molecules that modulate host environmen...

A postharvest treatment with hot air (48 C during 3 h) was applied to fresh-cut broccoli to investigate its effect on quality and senescence during storage at 0 C. The treatment delayed yellowing as evidenced by lower decrease of Hue values during storage. After 21 days of storage, treated broccoli had chlorophyll content approximately 40% higher than controls. The treatment did not affect eith...

Cassava roots are an important source of dietary and industrial carbohydrates and suffer markedly from postharvest physiological deterioration (PPD). This paper deals with metabolomics combined with chemometric tools for screening the chemical and enzymatic composition in several genotypes of cassava roots during PPD. Metabolome analyses showed increases in carotenoids, flavonoids, anthocyanins...

Fresh fruits and vegetables typically have a limited shelf life due to their high moisture content perishable nature. Notably, long global import export supply chains can lead an increased risk of food loss. The main underlying drivers for such loss are air temperature, relative humidity, but also ripening gases influenced by the product's postharvest physiology. These factors quality variation...

Wide international interest in heat treatments for maintenance of postharvest quality, disease control, and as a quarantine technology, was reflected in the range of papers presented at this BARD Workshop on Postharvest Heat Treatments. Heat treatments are currently used commercially in several countries, for example as hot water dips, hot water brushing techniques, and hot air treatments. Rese...

This article aims to give a comprehensive review on the use of microbial antagonists (fungi and bacteria), botanicals and compost extracts as biocontrol agents against different pathogenic fungi causing postharvest fungal rots in rosaceous fruits which shows that they can play an important role in the biomanagement of fungi causing rot diseases. Plant extracts reported in the literature against...

Nine oxylipin mimics were designed and synthesized starting from d-mannose. Their antifungal activity against three citrus postharvest pathogens was evaluated by spore germination assay. The results indicated that all the compounds significantly inhibited the growth of Penicillium digitatum, Penicillium italicum and Aspergillus niger. The compound (3Z,6Z,8S,9R,10R)-octadeca-3,6-diene-8,9,10-tri...

Tendral type cultivar melons (Cucumis melo L., inodorus group, Winter melon variety) were stored for a 75-d postharvest period in a ventilated chamber at 10 oC ± 1 oC and 75% ± 5 % RH. Qualitative degradation of the fruit was observed mainly involving proteins and ascorbic acid. It was also found that the sugar/acid ratio increased while the glucose/fructose ratio decreased, thus making the fru...
