| Five yield traits were investigated in three-year-old progenies from open-pollinated rubber trees [Hevea brasiliensis (Willd. ex Adr. de Juss) Muell.-Arg.]. Twenty progenies were evaluated in a randomized, complete block design replicated three times using 10 plants per linear plot at the North Central Experimental Station in Pindorama, São Paulo State, Brazil. The characters evaluated included the average yield of rubber, growth vigor, bark thickness, total number of latex vessel rings and latex vessel size. Highly significant (p < 0.01) genetic differences were observed among progenies for most traits. The genotypic variance components accounted for 13.2%, 12.3%, 9.4%, 3.4% and 0.23% of the phenotypic variance for yield, growth vigor, bark thickness,... |

| Realizou-se a caracterização do teor de cafeína no tegumento e amêndoa de sementes de plantas matrizes de guaraná (Paullinia cupana (Mart.) Ducke) existentes no Instituto Agronômico, no Vale do Ribeira,SP. Os teores de cafeína apresentaram valores médios de 2,33 ± 0,38% na amêndoa, de 1,09± 0,29 no tegumento e de 2,15± 0,34% na semente como um todo. |
