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...

The effects of fruit bagging treatments with seven different types bags on the physicochemical characteristics three table grape cultivars: RuiduZaohong (RDZH), RuiduHongyu (RDHY), and RuiduHongmei (RDHM) were investigated. Headspace-solid-phase micro-extraction combined gas chromatography mass spectrometry (HS-SPME-GC-MS) was used to determine compositions monoterpenes in fruit. results showed...

Two modern laser-based techniques were synchronously applied to study the dynamics of the trans-resveratrol activity in Botrytis cinerea-infected grapes. Direct analysis of trans-resveratrol in both infected and noninfected grapes (Vitis vinifera, Aledo variety) was performed by using an analytical technique incorporating laser desorption coupled with laser resonant ionization and time-of-fligh...

Different soil types can significantly affect the composition of wine grapes and the final wine product. In this study, the effects of soil types on the composition of Cabernet Sauvignon grapes and wine produced in the Helan Mountains were evaluated. Three different representative soil types--aeolian, sierozem and irrigation silting soil were studied. The compositions of grapes and wines were m...

AIMS To identify ascomycetous yeasts recovered from sound and damaged grapes by the presence of honeydew or sour rot. METHODS AND RESULTS In sound grapes, the mean yeast counts ranged from 3.20 +/- 1.04 log CFU g(-1) to 5.87 +/- 0.64 log CFU g(-1). In honeydew grapes, the mean counts ranged from 3.88 +/- 0.80 log CFU g(-1) to 6.64 +/- 0.77 log CFU g(-1). In sour rot grapes counts varied betwe...

Tempranillo grapes were immersed in solutions of pyrimethanil, metalaxyl, dichlofluanid and penconazol fungicides at different concentrations for several different times. Determinations of the fungicide residues was carried out by GC-NPD, with an additional confirmation by GC-MS. The percentage absorption was determined as well as the distribution between surface, skin and pulp of the grapes. T...

What soils are best for grapes? The best grape soils are deep, well-drained loams, free from high concentrations of alkali, boron, or other toxic materials. Deeper soils produce the heaviest crops and are preferred for raisins, common wine grapes, and some varieties of table grapes. However, grapes are adapted to a wide variety of soil types and can be grown successfully on soils not suitable f...

Road traffic crashes in Gulf Cooperation Countries (GCC) is considered a serious problem that has deep effects on GCC's population as well as on the national productivity through the loss of lives, injuries, property damage and the loss of valuable resources. Thus, there is an urgent need to alleviate the Severity of the traffic safety problem in GCC, which in turn will set a prime example for ...
