During 2010 and 2012 grape harvest seasons in Gyeonggi-do, Korea, a white stain symptom was observed on the harvested grape fruits in 'Campbell-Early' and 'Kyoho' varieties. In samples collected from the infected vine, two different strains of pathogenic fungi have been found and identified as Acremonium acutatum and Trichothecium roseum based on fungal morphology and nucleotide sequence of int...

Molecular information of K+ accumulation in grapes is strongly required. Under salinity condition potassium transporters are inhibited by Na+. The aim of this study was to investigate the effects of salinity on the expression of K+ transporter genes in grape. Based on the previous screening study on 18 grape genotypes, ‘H6’ and ‘Gharashani’ (tolerant) and ‘Shirazi’ and ‘GhezelUzum’ (sensitive) ...

A liquid chromatographic method for the determination of ochratoxin A in grapes, dried vine fruits, and winery byproducts was developed. A mixture of either acetonitrile/water or acetonitrile/water/methanol was used as an extraction solvent mixture. After immunoaffinity column cleanup, the final extract was analyzed by high-performance liquid chromatography (HPLC) with a fluorometric detector (...

Mendelian randomisation is a technique for assessing causal associations in observational data. Genetic variants associated with the risk factor of interest are regarded similar way to random assignment clinical trial. The difference due genetic variation, however, materially distinct from change any proposed therapeutic intervention and so might affect outcome differently. Consequently, it can...

BACKGROUND Melolonthinae beetles, comprising different white grub species, are a globally-distributed pest group. Their larvae feed on roots of several crop and forestry species, and adults can cause severe defoliation. In New Zealand, the endemic scarab pest Costelytra zealandica (White) causes severe defoliation on different horticultural crops, including grape vines (Vitis vinifera). Underst...

Studies were conducted to examine the spatial distribution of immature Bemisia argentifolii Bellows & Perring and immature Eretmocerus eremicus Rose & Zolnerowich on cantaloupe vines and to develop efÞcient sampling plans. More B. argentifolii eggs were found on the 3rd leaf from the terminal of a cantaloupe vine than on any other leaf. The density of whiteßy nymphs peaked at leaf position 8, w...

Abstract Guignardia bidwellii , indigenous to North America, is a significant pathogen of grapes long known in Hungary, infecting only the growing green parts vine (leaves, petioles, shoots, and bunches). In absence adequate plant protection extreme weather conditions such as predominantly humid, warm year, black rot can be expected. The cause high yield losses due grape reduce wine quality if ...

Ground-based proximal sensing of vineyard features is gaining interest due to its ability to serve in even quite small plots with the advantage of being conducted concurrently with normal vineyard practices (i.e., spraying, pruning or soil tilling) with no dependence upon weather conditions, external services or law-imposed limitations. The purpose of the present work was to test performance of...
