Seeds dispersal, regeneration and regrowth of Pinus taeda in North Plateau of S...

Pinus plantations cover approximately 1.6 million ha in Brazil. Since pines are considered to be alien invaders with the potential to modify natural environments, the aim of this study was to evaluate seed dispersal, establishment and control of Pinus taeda L., in order to characterize its biological invasion potential under different situations. We studied the dispersal/viability of pine seeds at 25 m, 50 m, 7...

Survival and growth of Cedrela fissilis (Vell.) in mixed species forest plantat...

Repeatability and genetic dissimilarity using biometric traits of black wattle ...

Disinfection and in vitro establishment of Acacia mearnsii nodal segments

Due to low rates of rooting it is difficult to propagate selected clones of Acacia mearnsii by cuttings. The purpose of this study was to define a protocol for disinfection of nodal segments for in vitro introduction, aiming to improve the species genetically for forest plantation. Combination of different products concentration (70% ethyl alcohol, sodium hypochlorite, plant preservative mixture and mercuric ch...

Genetic diversity of Cedrela fissilis (Vell.): insights on conservation and pro...

Dendroecology of Cedrela fissilis from Araucaria Forest

Although the wood from Cedrela fissilis Vell. has great commercial interest, its use is limited due to the lack of information regarding forestry of the species. The aim of this study was to evaluate growth and its correlations with climate variables in six districts at the eastern border of Paraná and Santa Catarina states. Radial wood samples were collected from 42 individuals. Once dried and sanded the annua...

Prediction methods and heterogeneity effects of residual variances within genet...

The aim of this study was to compare, through simulation, the BLUP and BLUP-HET procedures for breeding values prediction under heterogeneity of residual variances. Random data were generated with spread sheet, considering a variance of 0,10 and variable residual variance, by number of clones, in order toprovide heterogeneity of variances. Actual and residual breeding values obtained were added to the mean 10, ...

Influence of soil physical characteristics on growth of Pinus taeda growth

The objective of this study was to assess variability of Pinus taeda L. growth in function of the soil physical characteristics. The soils data were obtained from a detailed mapping, in the scale 1:10,000, in two areas of the Forest Company – Battistella Florestal, located in the states of Santa Catarina and Parana. Data on forestry growth was collected from continuous forest inventory, obtained from a populati...

Methodology for sporulation and production of monoconidial isolates of Sphaerop...

Sphaeropsis sapinea is one of main pathogens that causes losses in commercial plantations of Pinusspp. Studies for control based on genetic resistance can be done by inoculating different monosporic isolates onpine populations and selectioning the resistant individuals. This work describes a methodology for pycnidia production in vitro and S. sapinea monoconidial cultures, using an agar-water medium with steril...

Eucalyptus badjensis Beuzev. & Welch Progenies Behavior in Two Sites of Souther...

This paper analyzes Eucalyptus badjensis Beuzev. & Welch half sib progenies planted in two areas of Southern Brazil. The species is considered potential for plantation in frost prone areas and for oil production (1,8 cineol). Height and DBH growth were fast on both areas, Vargem Bonita (SC) and Ponta Grossa(PR). In the colder area the species showed higher survival rate and no signal of frost damage. Herita...
