| Abstract | The contaminations of fungi and Orchratoxin A at 4 growth stages of grape werestudied in 4 famers, vineyard. The first stage of growth was 30-40 days after fruit set andthe second, third and fourth were 60-70, 90-100 and 120 days after fruit set, respectively.In every vineyard, the average Orchratoxin A of the first and second stages were 7.95-119.0 ?g/kg which were higher than the third and fourth stages (2.90-20.3 ?g/kg).Penicillium spp. and Aspergillus aculeatus were found to produce a toxin whereasAlternaria spp., Curvularia spp. and Cladosporium spp. did not produce the toxin. Soil ineach vineyard was investigated for fungi contamination by dilution plate count and air wasinvestigated by settle plate. The amounts of Penicillium spp. and A. aculeatuscontamination in grape were high which correlated to increase of Orchratoxin Aconcentration detected in the fruit. Fungi and Orchratoxin A could contaminate in everygrowth stage of grape. Therefore, a good management from planting to harvest must beconsidered to reduce the amout of fungi and Orchratoxin A contamination. |
