متن کاملAumento da Eficiência das Estruturas de Indexação Métricas com Uso de Conceitos da Lógica Nebulosa
The retrieval of complex data e.g. image, audio, video, genomic sequences etc. in Database Management Systems (DBMSs) has been in the focus of the academic community and of DBMSs developers. The most promising technique is the content-based search, in which a set of descriptors with high discrimination power is extracted from each data element, and a feature vector is obtained and used to index...
متن کاملVirulence and rep-PCR Analysis of Pyricularia grisea Isolates from Two Brazilian Upland Rice Cultivars
The phenotypic and genetic diversity of 77 isolates of Pyricularia grisea collected from two upland rice cultivars, Maravilha and Primavera, was studied. Isolates exhibiting compatible reaction to cv.Primavera were incompatible to cv.Maravilha and vice versa, with the exception of six isolates that were compatible to both cultivars. The virulence of isolates from cv. Maravilha on 32 test genoty...
متن کاملVirulence Pattern of Pyricularia grisea Isolates from Farmers’ Fields on Newly Released Upland Rice Cultivars
The virulence pattern of the isolates of Pyricularia grisea from commercial fields of the upland rice (Oryza sativa) cultivars ‘Primavera’ and ‘BRS Bonança’ was analyzed. A hundred and seventy monoconidial isolates of the pathogen virulent to ‘Primavera’ and 139 to ‘BRS Bonança’ collected from eight fields, during two years (2001-2003) were tested, under greenhouse conditions, on six newly rele...
متن کاملCharacterization of a Pyricularia grisea population from Uruguay by molecular analysis.
Blast disease, caused by hemibiotrophic fungus Pyricularia oryzae Sacc. (teleomorph: Magnaporthe oryzae (Hebert) Barr.), previously known as Magnaporthe grisea, is the most serious disease of rice and causes high yield losses in most rice growing regions every year. Blast is an endemic disease in all Iranian and Uruguayan rice fields, with yield losses up to 90 % that has been reported from som...
