Conteúdo: | During the period 1982-92, 9952 accessions of 24 species, from field collections and research centres of EMBRAPA, were evaluated in relation to sanitary conditions before storage. Aspergillus and Penicillium were the fungi most frequently found associated with the seeds. The main pathogenic fungi detected were Pyricularia oryzae [Magnaporthe grisea], Drechslera oryzae [Cochliobolus miyabeanus] and Gerlachia oryzae in rice; Drechslera sorokiniana [Cochliobolus sativus] in wheat, D. teres [Pyrenophora teres] in barley, Diplodia maydis [Stenocarpella maydis] and Fusarium moniliforme [Gibberella fujikuroi] in maize; Colletotrichum lindemuthianum, Rhizoctonia solani, Macrophomina phaseolina and Sclerotinia sclerotiorum in bean (Phaseolus vulgaris) and Colletotrichum dematium, and Phomopsis sojae [Diaporthe phaseolorum var. sojae] in soyabeans. These results showed that seed health tests are extremely important in order to assure the maintenance of high quality germplasm, avoiding the conservation and dissemination of pathogens.
