Abstract

The micromycetes presented on different vegetables seeds, stored in various atmospheric conditions.

Abstract

Studies were conducted to determine the micromycete spectrum of carrot, sweet pepper, parsley, lettuce, watermelon, garlic and tomato seeds stored in various atmospheric conditions. Samples were taken from the stored seeds for the determination of the fungal spectrum. Seeds were placed on PDA plates and stored for 5 days at 22°C. After incubation, the PDA plates were microscopically analysed to establish the number of fungal colonies and the area occupied by these colonies. Results showed that Rhizopus stolonifer, Penicillium sp., Cladosporium sp., Alternaria sp., Thamnidium elegans and Thanatephorus cucumeris were the fungi present on carrot seeds, Penicillium sp. and Cladosporium sp. were present on sweet pepper seeds, Rhizopus sp., Penicillium sp., Mucor sp., Alternaria sp., Trichothecium sp., Fusarium sp., Cladosporium sp., Rhizoctonia sp., Pleospora herbarum and Scopulariopsis sp. were present on tomato seeds, Rhizopus sp., Aspergillus sp., Penicillium sp., Alternaria sp., Cladosporium sp., Rhizoctonia sp., Mucor sp., Fusarium sp. and Stemphylium sp. were present on parsley seeds, Alternaria sp., Mucor sp., Cladosporium sp., Fusarium sp., Stemphylium sp. and Trichothecium sp. were present on lettuce seeds, Alternaria sp., Rhizopus sp., Mucor sp., Cladosporium sp., Fusarium sp., Stemphylium sp., Rhizoctonia sp. amd Penicillium sp. were present on watermelon seeds and Trichothecium sp., Alternaria sp., Mucor sp., Stemphylium sp. and Rhizopus sp. were present on garlic seeds. These results showed that these seed samples were stored under improper conditions and it was recommended to treat seeds before dissemination.
