The effects of edible chitosan coating (0.1%, 0.3%, 0.5% and 0.75% w/v) on the changes in quality, respiration rate, total phenolic content anthocyanin postharvest sweet cherry (Prunus avium L.) at 10 °C were investigated. activities superoxide dismutase (SOD), catalase (CAT) ascorbate peroxidase (APX) also determined. result showed that treatments effective delaying evolution parameters relate...

'Bing' cherries, Prunus avium L., were obtained from an organic orchard and a conventional commercial orchard. The two groups were examined separately in replicated tests infested with each fruit initially infested with a first-instar codling moth, Cydia pomonella (L.). To simulate commercial postharvest holding conditions, the treatments were 0 (control), 1, 2, 4, 7, 10, and 14 d cold storage ...

Ann. Entomol. Soc. Am. 84(5): 488-492 (1991) ABSTRACT The flight period of the western cherry fruit fly, Rhagoletis indifferens Curran, was investigated in Utah tart cherry, Prunus cerasus L., orchards from 1983 to 1989 and in Washington sweet cherry, Prunus avium L., orchards between 1982 and 1988. In Utah, flies were first detected on 31 May 1989, but the average time of first detection was 9...

Honeybee colonies are declining in some parts of the world. This may have important consequences for the pollination of crops and native plant species. In Spain, as in other parts of Europe, land abandonment has led to a decrease in the number of non professional beekeepers, which aggravates the problem of honeybee decline as a result of bee diseases In this study, we investigated the effects o...

Prevailing ambient temperature during the reproductive phase is one of several important factors for seed and fruit set in different plant species, and its consequences on reproductive success may increase with global warming. The effect of temperature on pollen performance was evaluated in sweet cherry (Prunus avium L.), comparing as pollen donors two cultivars that differ in their adaptation ...

In this study the abundance and location of phosphoenolpyruvate carboxykinase (PEPCK) was determined in the flesh and skin of the sweet cherry (Prunus avium L.) cultivar Durone Nero II during development. PEPCK was not present in young fruit but appeared in both tissues as the fruit increased in size. In these there was no net dissimilation of malic acid, which accounts for the bulk of their or...

The diurnal and seasonal activity patterns of the western cherry fruit ßy, Rhagoletis indifferensCurran,weredeterminedon three sweet cherry trees,Prunus avium (L.), from0700 to 1900 hours during June and July 2001 in Yakima County, WA. There were signiÞcant effects of time of day and season on numbers of ßies seen on fruit relative to leaves, indicating that presence on or attraction to these s...
