ABSTRACT Penicillium expansum, P. digitatum, and P. italicum acidify the ambient environments of apple and citrus fruit during decay development. They use two mechanisms for this: the production of organic acids, mainly citric and gluconic, and NH(4)(+) utilization associated with H(+) efflux. Exposure of P. expansum and P. digitatum hyphae to pH 5.0 increased their citric acid production, comp...

Loquat (Eriobotrya japonica Lindl.) is a subtropical evergreen tree whose fruit is consumed both fresh and processed. Loquat fruit is a good source of minerals and carotenoids, while the kernel is rich in protein and carbohydrates. It has been considered a non-climacteric fruit, but there is evidence that some cultivars have a ripening pattern similar to that of climacteric fruits. The fruit ha...

The beneficial effects of proper temperature management include reduced decay, improved firmness and skin color, greener stems, and reduced pitting. Improper handling temperature rapidly reduces shelf life. Modified atmosphere packaging has lengthened the postharvest life of cherry fruit by reducing the rate of growth of decay organisms, retarding softening and retaining stem color. Modified at...

Apple ( X Borkh.) is one of the world's most valuable fruit crops. Its large size and long juvenile phase make it a particularly promising candidate for marker-assisted selection (MAS). However, advances in MAS in apple have been limited by a lack of phenotype and genotype data from sufficiently large samples. To establish genotype-phenotype relationships and advance MAS in apple, we extracted ...

A total of seven samples of bottled fruit juice produced and consumed in Nigeria were used for the study. The average concentrations of radionuclides contained in some bottled fruit juice produced and consumed in Nigeria and also exported to neighboring countries have been estimated by means of scintillation detector which is sodium Iodide activated with thallium (Na (Ti)). The radionuclides ob...

Practices in the citrus industry evolve rapidly to minimize postharvest decay losses, mostly a result of green mold or blue mold, caused by Penicillium digitatum or P. italicum, respectively. Current problems include the continued development of fungicide resistance among these pathogens, and compliance with emerging secondary residue standards and other privatized regulation of production and ...

Blueberries (Vaccinium corymbosum, cvs. Collins, Bluecrop) were exposed to ultraviolet light-C (UV-C) radiation treatments from 0 to 4 kJ/m2 rior to 7 days storage at 5 ◦C plus 2 days at 20 ◦C, 90% RH. Weight loss and firmness were not affected by light treatment. Decay incidence from ipe rot (Colletotrichum acutatum, syn. C. gloeosporioides) on fruit was decreased by 10% with 1–4 kJ/m2 UV-C li...

The efficacy of hot water, biological control and controlled atmospheres (CA), alone and in combinations, in controlling gray mold on harvested strawberry fruit was tested. All fruit were wound inoculated with Botrytis cinerea Pers.:Fr. Inoculated fruit were subsequently dipped in hot water at 63 8C for 12 s, inoculated with a biological control yeast, Pichia guilliermondii Wickerham, and/or im...

Grapes are one of the important fruit crop in the world, with production rates of approx. 50 million tons per year (Schieber et al., 2001). Grapes can be decay during pre harvest and post harvest and post harvest decay of grapes can be due to physical, physiological, or pathological factors. Rachis dehydration is a main decay factor (physical deterioration) of grapes during the pre or postharve...
