| beneficial effects of chrysin and benzoflavone on virility in 2-year-old male rats. | this work describes the potential usefulness of bioflavonoids for countering the deleterious effects of aging on male sexuality in 2-year-old rats. a flavone chrysin from passiflora caerulea linn. and a benzoflavone moiety (bzf) recently isolated from passiflora incarnata linn. were administered to 2-year-old male rats for a period of 30 days. after cessation of these treatments, there was a significant improvement in overall sexual functions in the rats given bioflavonoids, compared with contro ... | 2002 | 12511112 |
| oidium neolycopersici: intraspecific variability inferred from amplified fragment length polymorphism analysis and relationship with closely related powdery mildew fungi infecting various plant species. | previous works indicated a considerable variation in the pathogenicity, virulence, and host range of oidium neolycopersici isolates causing tomato powdery mildew epidemics in many parts of the world. in this study, rdna internal transcribed spacer (its) sequences, and amplified fragment length polymorphism (aflp) patterns were analyzed in 17 o. neolycopersici samples collected in europe, north america, and japan, including those which overcame some of the tomato major resistance genes. the its s ... | 2008 | 18943220 |
| native and introduced host plants of anastrepha fraterculus and ceratitis capitata (diptera: tephritidae) in northwestern argentina. | wild or commercially grown, native and exotic fruit were collected in 30 localities in the tucumán province (nw argentina) from january 1990 to december 1995 to determine their status as hosts of anastrepha fraterculus (wiedemann) and/or ceratitis capitata (wiedemann), the only two fruit fly species of economic and quarantine importance in argentina. a total of 84,094 fruit (3,466.1 kg) representing 33 species (7 native and 26 exotic) in 15 plant families were sampled. we determined the followin ... | 2003 | 14503581 |
