Última Genetic Gain for Wood Volume in Progeny Trial of Grevillea robusta Cunn (Breeding Cycle 2) in Londrina, Paraná State PFB - Pesquisa Florestal Brasileira Martins, Emerson Gonçalves; Neves, Edinelson José Maciel; Sturion, José Alfredo; Duleba, Nicole. Twenty and twenty three seed provenances of Grevillea robusta 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 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...

Ano: 2011 URL: http://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/226 Sweetgum for wood production in the South and Southeastern Brazil PFB - Pesquisa Florestal Brasileira Shimizu, Jarbas Yukio. Sweetgum is a North and Central American tree species well known for the healing gum since the times of the Aztec civilization. In the southern United States, this is the most widely planted broadleaf species for wood  production. It grows well on a variety of site conditions, including on alluvial soil prone to flooding. As a result  of the wide natural distribution, it shows important variations in phenology and growth traits. The more  northern provenances tend to shut down growth processes much earlier and resume them later than the southern sources. These variations reflect directly on  the growth patterns among seed sources. Experiments  in several sites have demonstrated its potential value for wood production in small wood lots in the South and...

Ano: 2011 URL: http://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/246 Genetic Gain for Wood Volume in Progeny Trial of Grevílea (Breeding Cycle 2) in Avaré, State of São Paulo PFB - Pesquisa Florestal Brasileira Martins, Emerson Gonçalves; Neves, Edinelson José Maciel; Sturion, José Alfredo; Aoki, Hideyo. 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...
