| The grevilea, Grevillea robusta (Cunn), species of the Proteaceae family, native of Australia it was introduced in Brazil and in several other countries of the world, for ornamentation, wind breaks and to shade agricultural crops. In general the grevilea has few pests in its area of natural dispersion and also in Brazil. Recently a severe infestation of the cicada Aethalion reticulatum (Hemiptera: Aethalionidae) was verified in experimental plantings of grevilea’s plantation in São Miguel Arcanjo, SP. This is the first verification of A. reticulatum causing damages to G. robusta. A. reticulatum is an sap sucking insect and the damages in grevilea are similar to the observed in fruit plants. |

| Foram avaliadas a deposição de serapilheira e de nutrientes em quatro procedências de grevilea (Grevillea robusta Cunn), de quatro anos de idade, plantadas na Região de Quedas do Iguaçu, em solo classificado como LATOSSOLO VERMELHO Distroférrico (Haplustox). Os resultados possibilitaram as seguintes conclusões: 1) A grevilea produz em média 10267 kg de serapilheira por hectare/ano, superando as produções observadas em povoamentos de Pinus e Eucalyptus. 2) A concentração dos macronutrientes na serapilheira não tem relação com o crescimento volumétrico, exceto de P, que se apresenta em maior concentração em povoamentos com a menor produção volumétrica de média. 3) As procedências mais produtivas em madeira tenderam a depositar, pela serapilheira, as maiores... |

| An experiment was established in Paranaguá, located in the costal region of the State of Paraná, in southern Brasil, in order to evaluate commercial yield of hearth-of-palm produced by Peach-Palm (Bactris gasipaes) established under the following four different initial spacings: T1 2x1m (5000 seedlings/ha); T2 3x1m (3333 seedlings/ha); T3 1,5x1x1m (8000 seedlings/ha); and T4 2x1x1m (6666 seedlings/ha). Mineral fertilizers (NPK) were applied at planting as well as subsequently. Results obtained by the time of the first cutting, 24 months after planting, allowed the following conclusions: a) the quantities of the NPK fertilizer used promoted changes in the chemical soil characteristics; b) commercial yield of hearth-of-palm improved as a function of stand... |

| Twenty one provenances of Grevillea robusta Cunn were tested at Nova Esperança and Quedas do Iguaçu, Paraná state and Anhembi, São Paulo state, Brazil. With the aim of comparing the performance of the original provenances with the comercial provenance collected in Maringa, Paraná state included as a control. Provenance trials were installed in a randomized block design with rectangular plots, each one with six plants spaced 3 m x 3 m, with 15 replications. Five among the ten best provenances at Anhembi presented better growth at Quedas do Iguaçu and Nova Esperança (Duck Creek, Fine Flower, Rappville, Bottle Creek and Mc Pherson’s Creek). Different environments did not interfere significantly in the average growth among different provenances indicating that... |

| Twenty and twenty three seed provenances of Grevillea robusta A. Cunn. were imported from Australia, in 1993 and 1994, respectively, by Embrapa Florestas. This genetic germoplasm was utilized for starting a breeding program in the states of Paraná, São Paulo and Mato Grosso do Sul. In 2002, twenty eight genotypes were selected in the Presidente Castelo Branco-PR district whose seeds were utilized for the installing second generation progenies test in Avaré-SP. Randomized blocks was the statistical design utilized, with linear plots of five plants, adjusted in a compass 3m x 3m, with 8 replications. Total height, DBH (diameter at the height of breast) were the characteristics considered in the volume evaluations. Estimation of variance components, genetic... |

This genetic germoplasm was utilized for starting a breeding program in the State of Paraná, São Paulo and Mato Grosso do Sul. Total surface occupied by Grevillea experiments managed by Embrapa Florestas reachs 27,13 ha, being provenance tests, embracing 11,22 ha, installed in 1994, and progenies tests, comprising 15,91 ha, planted in 1994. In the Presidente Castelo Branco District it was introduced a provenance/progenie test with 104 progenies and 20 provenances. In 2001, it was selected the best genotypes and the experiment was transformed in a Seed Orchard. In 2002, 37 genotypes were selected at the same... |

| The coast region of Paraná State, Brazil, has a great potential for growing of pupunha trees aiming palm heart production due to climate conditions. There were around one million pupunha trees planted at small farmers area, totalizing about 200 ha, in this region by the end of 2004. This fact confirms the specie as a sustainable and economicaly viable alternative for small farmers as long as the natural stands of juçara (Euterpe edulis) are raryng. This paper aimed to evaluate the palm heart production, at ages 24 and 39 months after planting, from plants growing instands varyng on plant density and soil class and considering processing as heart, ring and chopped. The experiment was set up in two areas located along the Alexandra-Matinhos Road (km 7 and km... |

| O objetivo deste trabalho foi estimar a variação radial da densidade básica em amostras de madeira de diferentes procedências de Grevillea robusta Cunn. As amostras foram retiradas de árvores com sete anos, de um teste de procedência instalado em área da Itaipu Binacional, Município de Foz do Iguaçu, Paraná. As árvores foram selecionadas em três níveis, de acordo com o seu crescimento volumétrico, classificado como excelente, intermediário e lento. Foram retiradas amostras de casca a casca da tábua central da parte superior da primeira tora. Estas foram subdivididas em amostras de 1,0 cm na direção radial. A densidade básica foi determinada para cada sub amostra, e foi estabelecida a percentagem de variação radial, considerando o maior e o menor valor da... |

| A provenance/progenies trial of grevílea (Grevillea robusta Cunn.) was established in the Ponta Grossa region, state of Paraná, Brazil. The purpose was to identify genetically superior individuals in order to assure good material for future seed orchard. The genetic matherial was based on 60 half-sib progenies from eighteen Australian provenances and one control. Progenies were evaluated in randomized blocks with seven replications, five plants per plot and spacing of 3 m x 3 m (9 m2 per plant). Significant gains were estimated through selection of the 200 best trees (23,33%), for cilindric volume, at 10 years age, based on genetic values, aiming to establish a seedling seed orchard; or selecting the best twenty trees (33,33%), towards a clonal seed orchard. |
