Several studies have revealed that fruit-zone leaf removal could change the microclimate of grapevine growth, thereby causing complex effects on fruit composition. This study analyzed profiles volatiles in Cabernet Sauvignon (Vitis vinifera L.) grapes exposed to treatment at different phenological periods three continuous years. The treatments (leaf before flowering, after and veraison) were ap...

The spatial distribution of organosulphur compounds throughout the onion ( Allium cepa L.) plant body during reproduction is of ecological and horticultural interest. These secondary metabolites are associated with both pest resistance and many of the vegetable’s culinary and medicinal properties, including the ability to inhibit platelet aggregation. Inhibition of platelet aggregation can be o...

The purpose of the study was to compare basic fruit chemical composition of four highbush blueberry cultivars: ‘Spartan’, ‘Bluecrop’, ‘Jersey’ and ‘Blueray’. The plants were grown on plantation near Szczecin in the years 2001 – 2003. Basic chemical composition of fruit including total ash, crude fibre, total nitrogen, soluble solids, titratable acidity, dry weight and total polyphenol content w...

The feasibility of the compartmentalized anaerobic migrating blanket reactor (AMBR) was studied for the treatment of low-strength soluble wastewater under low-temperature conditions. During an operating period of 186 days, a 20-L AMBR was fed nonfat dry milk substrate as a synthetic wastewater at low temperatures (15 and 20 degrees C). The concentration of the influent was constant at chemical ...

ABSTRACT: Edible coatings made from whey protein concentrate (WPC) and gellan gum (G) were investigated for their capacity to preserve the quality of Malus domestica cv Golab apples. WPC and gellan gum coatings at different concentrations plasticized with glycerol (Gly) were tested. Postharvest storage quality condition testes included weight loss, color and texture changes, titratable acidity ...

cantaloupe is a common crop and relatively important in iran which show high genetic diversity. forty nine genotypes including seven iranian endemic cantaloupes rishbaba, shahabadi, samsori, dastjerdi, magasi, tiltorogh and savei and their direct and reciprocal crosses were evaluated during two years using triple lattice design. results indicated the positive and significant correlations betwee...

A technologically and economically feasible process called bioleaching was used for the removal of heavy metals from livestock sludge with indigenous sulfur-oxidizing bacteria in this study. The effects of sludge solids concentration on the bioleaching process were examined in a batch bioreactor. Due to the buffering capacity of sludge solids, the rates of pH reduction, ORP rise and metal solub...

this paper reports on the use of artificial neural networks (ann) and partial least squareregression (pls) combined with nir spectroscopy (900-1700 nm) to design calibration models for thedetermination of sugar content in sugar beet. in this study a total of 80 samples were used as the calibration set,whereas 40 samples were used for prediction. three pre-processing methods, including multiplic...

Background: Considering the toxic effects of heavy metals and microbial pathogens in industrial wastewaters, it is necessary to treat metal and microbial contaminated wastewater prior to disposal in the environment. The purpose of this study is to assess the removal of heavy metals pollution and microbial contamination from a mixture of municipal and industrial wastewater using membrane bioreac...
