Afilamento e otimização de sortimentos de Tectona grandis Linn.f. para a maximização do volume e da renda
(Universidade Federal de Santa MariaBrasilRecursos Florestais e Engenharia FlorestalUFSMPrograma de Pós-Graduação em Engenharia FlorestalCentro de Ciências Rurais, 2018-08-20)
The study was conducted in order to describe the shape of bole and evaluate the income from
assortments of trees coming from Tectona grandis L.f plantations located in the central-south
region of Mato Grosso state, and ...
The use of linear mixed model theory for the genetic analysis of repeated measures from clonal tests of forest trees. I. A focus on spatially repeated data
(SPRINGER HEIDELBERG, 2008)
The paper reviews the linear mixed models (LMM) methodology that is suitable for the statistical and genetic analyses of spatially repeated measures collected from clonal progeny tests. For example, we consider a poplar ...
Identification and joint modeling of competition effects and environmental heterogeneity in three Douglas-fir (Pseudotsuga menziesii var. menziesii) trials
(2016-12)
(Co)variance matrices for the assumed model, and thus the specification of the dispersion parameters, should take into account both the negative competition and the positive spatial correlations. In this context, we applied ...
Tree age and bark thickness as traits linked to frost ring probability on Araucaria araucana trees in northern Patagonia
(Elsevier Gmbh, Urban & Fischer Verlag, 2016-03)
Frost events may damage the cambium and consequently the newly produced tracheids whose cell walls have not yet completed their lignifications, leading to the formation of frost rings. This study deals with the presence ...
Accounting for competition in multi-environment tree genetic evaluations: a case study with hybrid pines
(EDP Sciences, 2021-01-06)
Key message: A novel multi-environment competition individual-tree mixed model resulted in better fit, and greater individual narrow- and broad-sense heritabilities than the model without competition, notably for traits ...

The study is located at the Federal Technological University of Paraná, in the city of Two Neighbors / PR and intended to adjust mixed effect models for determination of the growth in diameter of Hovenia dulcis species and ...
Estimation of variance components and prediction of breeding values in rubber tree breeding using the REML/BLUP procedure
(2005-12-01)
The present paper deals with estimation of variance components, prediction of breeding values and selection in a population of rubber tree [Hevea brasiliensis (Willd. ex Adr. de Juss.) Müell.-Arg.] from Rio Branco, State ...

Restabelecimento de Araucaria angustifolia e Ocotea porosa após sete décadas da exploração florestal
(Universidade Federal de Santa MariaBRRecursos Florestais e Engenharia FlorestalUFSMPrograma de Pós-Graduação em Engenharia Florestal, 2015-03-31)
Research in the growth of tree species are very important for the management and conservation of forest remnants. Disturbances that occur in the forest are responsible for the dynamic formation of gaps, which directly ...
