RESUMO - Em três experimentos, em andamento, em áreas do Latossolo Amarelo, textura argilosa, de baixa fertilidade natural, boa profundidade e bem drenado, ocorrente em áreas do Centro Nacional de Pesquisa de Seringueira e Dendê (CNPSD), em Manaus, AM, estio sendo avaliados a produção e o desenvolvimento de 48 clones de seringueira (Hevea spp.) das séries Fx IAN, RRIM e alguns clones primários em diferentes idades. Foi utilizado o delineamento de blocos casualizados em dois ou três experimentos, com 10 e 25 plantas por parcela, respectivamente, com duas repetições, obedecendo ao espaçamento de 7 m x 3 m. 0 terceiro experimento foi delineado em látece tripo 5 x 5, com 20 plantas por parcela. Os resultados indicam que, dos 48 clones estudados, os clones Fx 3899, IAN 717, Fx 4098, IAN 6158 e IAN 6323 estão mostrando o melhor desempenho em relação à produção e ao vigor. ABSTRACT - Three experiments have been carried out to evaluate productivity and trunk growth of 48 rubber tree (Hevea spp.) clones of Fx, IAN and some other primary clones at different ages, in a clay-texture Kaolinitic Yellow Latosol at the National Rubber and Oil Palm Research Center at Manaus, State of Amazon, Brazil. Two of the experimental designs are randomized blocks of 10 and 25 trees per plot respectively, spaced 7 m x 3 m in two replications. The third one is an experimental design of 5 x 5 triple lattice of 25 trees per plot. The first results led to the conclusion that clones Fx 3899, IAN 717, Fx 4098, IAN 6158 and IAN 6323 give the test performance as to yield and vigor among the variables in the present study MenosRESUMO - Em três experimentos, em andamento, em áreas do Latossolo Amarelo, textura argilosa, de baixa fertilidade natural, boa profundidade e bem drenado, ocorrente em áreas do Centro Nacional de Pesquisa de Seringueira e Dendê (CNPSD), em Manaus, AM, estio sendo avaliados a produção e o desenvolvimento de 48 clones de seringueira (Hevea spp.) das séries Fx IAN, RRIM e alguns clones primários em diferentes idades.

Stratification and mixing patterns of a water body are influenced by the variability of atmospheric systems, which can also modify their biogeochemical properties. The primary goal of this study was to analyze the effect of atmospheric cold fronts (CFs) on thermal stratification and water quality parameters in 4 embayments of the Furnas Hydroelectric Reservoir (FHR) (southeastern Brazil), a warm monomictic water body. A secondary goal was to evaluate the implications of this effect on the aquaculture of Nile tilapia Oreochromis niloticus (L.) in net cages. A 2 yr dataset of meteorological and water quality parameters was used to compute heat flux balance components and buoyancy frequency. These parameters were used to evaluate the influence of CFs on FHR water column stability and water quality. It was observed that the passing of CFs increased net heat loss and wind velocity, resulting in a partial mixture of surface waters with deeper layers. These changes in the physical structure of the water column altered the diel cycle of water temperature, led to a slight decrease in dissolved oxygen concentrations and pH values during the stratification period, and contributed to the increase in dilution power at the fish cultivation sites. However, following CF passages, no significant changes were observed in water quality parameters that influenced Nile tilapia cultivation in the FHR. Nevertheless, the understanding of meteorological systems and their influence on the physical and biogeochemical properties of an aquatic system is important for optimal management of aquaculture activities.
