| O maracujazeiro está entre as principais frutíferas cultivadas no País, mas apresenta limitações no cultivo, ocasionando baixa produtividade, que pode ser superada através do uso da estaquia, clonando as melhores matrizes de alta produtividade. Com isso, o objetivo desta pesquisa foi avaliar o potencial de enraizamento de estacas no inverno e no verão, utilizando as espécies comerciais (P. edulis Sims f. flavicarpa Degener e P. alata Dryander) e os porta-enxertos (P. giberti N.E.Brown, P. nitida H.B.K. e P. setacea D.C.). Este experimento foi realizado no período de julho de 2001 a março de 2002, em câmara de nebulização intermitente, sob condições de telado (50% de sombreamento). As estacas foram coletadas de plantas adultas oriundas do Banco de... |

| Bi-parental families were produced in hatchery and tested in the field in 2001. Two sets of 5 families were constituted, selected on their high (R) and low (S) survival. These two sets were reared in Brittany from March to November 2002. Samplings were performed twice a month to obtain data on biometry, survival, reproductive cycle, biochemical composition, adenylate energy charge, hemolymph parameters (ions and defense system) and muscle strength. "R" and "S" oysters exhibited different reproductive effort and spawning strategy. "R" oysters allocated less energy in gonad than "S" ones and presented a complete spawning at the end of August contrary to the "S" which spawns partially. Mortality started in July when the seawater temperature reached 19 degree... |

| The French project "Morest", coordinated by IFREMER, aims to understand the causes of the summer mortalities in Crassostrea gigas. In 2001, three sets of families were bred following a nested half-sib mating design. 17 half-sib families (HSF) were obtained in this first generation (G1) and reared in 3 sites. Significant differences in survival were observed among HSF, and some HSF showed high levels of mortality in all sites, clearly indicating a genetic basis for survival. In 2002, a second generation (G2), including divergent selection and inbred lines, was constituted. Monitoring of survival and growth of G2s were the same as in 2001. Significant differences in survival were found between the offspring of the "high" and "low" selected groups and between... |
