Four hundred kernels of each of 82 imported seed lots were plated on each of three cultural media for the purpose of establishing the sanitary status of ceral seed produced in Brazil. The media were somewhat differential in revealing microorganisms. Of 32,800 seeds plated on potato-dextrose agar, 17,783 yielded a fungus colony. Alternaria spp. and Drechslera spp. were among the most frequently isolated fungi. The blotter method tended to favor the emergence of Cladosporium spp. and Drechdlera spp., while oxgall agar medium permitted the development of Septoria nodorum, Fusarium spp. and Pseudomonas syringae. in general, Brazil-grown seed was heavily laden with pathogens. Barley, with an infection level of 50.5%, was more infested than triticale (43.3%) or wheat (26.6%). Of undoubted significance was the fact that 88% of the seed lots were infected with Drechslera; 59% with Fusarium and 52 with S.nodorum. Seeds produced in Brazil had lower germination, lower emergence rate indices, and a higher rat of pathogen transmission to emerging seedlings than counterpart seeds produced in Pullman. Cereal seed produced in Pullman was virtually free of pathogens, indicating an inability of most organisms to persist from one host generation to the next in the dry climate attending crop maturation at Pullman. However, it was revealed for the first time that wheat seed produced under moist conditions of western Washington was sometimes infected with S.nodorum and Pseudomonas syringae.

The soybean (Glycine max L. Merr.) cultivar BRS 217 Flora was developed by Embrapa and released for production in the states of Goiás, Minas Gerais, Bahia, Mato Grosso and the Distrito Federal, Brazil. It is resistant to stem canker, frog-eye leaf spot, bacterial pustule, and partially resistant to powdery mildew. |
