  1. 1. Pine production comparison : production potential of Loblolly pine (Pinus taeda) and Slash pine (Pinus elliottii) in the southeastern USA in relation to initial density and forest management

    University essay from SLU/Dept. of Forest Resource Management

    Author : Åsa Ramberg; [2019]
    Keywords : Loblolly pine; Slash pine; Scots pine; management intensity; planting density;

    Abstract : The southeastern (SE) United States (US) produces more industrial timber than any other region in the world. Pine plantations in the southern US have increased from 1.8 million acres (728,400 ha) in the beginning of the 1950’s to 32 million acres (13 million ha) in the beginning of the 21st century, and cover 17 % of the forest land.

  2. 2. Reduction of Set-recovery of Surface densified Scots Pine by Furfuryl Alcohol

    University essay from Luleå tekniska universitet/Träteknik

    Author : Lei Han; [2019]
    Keywords : surface densification; set-recovery; hardness; furfuryl alcohol;

    Abstract :  For wood products such as flooring and worktop, only one surface is normally exposed in their use, and the mechanical properties like hardness and wearing resistance of that surface is then important. Since mechanical properties are strongly related to the density, surface densification, i.e. READ MORE

  3. 3. Skattningar av ståndortsindex – med flygburen laserskanning, allmänt tillgänglig information eller skördarmätningar?

    University essay from SLU/Dept. of Forest Resource Management

    Author : Karl Larsson; [2019]
    Keywords : ståndortsindex; flygburen laserskanning; skördardata; fjärranalys;

    Abstract : Ståndortsindex är en viktig faktor i det moderna skogsbruket, främst för att en ståndorts produktionsförmåga skattas via ståndortsindex. I operativt skogsbruk i Sverige idag skattas ståndortsindex genom inventering av relevanta variabler vid fältbesök. READ MORE

  4. 4. Phenotypic differences between plus-tree progenies of Sitka spruce (Picea sitchensis) and a comparison with Norway spruce (Picea abies)

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Teresa López-Andújar Fustel; [2019]
    Keywords : Picea sitchensis; growth; heritability; phenotypic and genetic correlations;

    Abstract : Forest productivity and economic gains are two of the most important aspects to consider when managing forests these days. The performance of these depends on rotation periods and yields providing new opportunities to maximize earnings from the forest site and plant material. READ MORE

  5. 5. Genetic diversity and hardiness in Scots pine from Scandinavia to Russia

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Jenny Olsson; [2019]
    Keywords : Pinus sylvestris; recolonization history; genetic diversity; cold hardiness; clinal variation;

    Abstract : The postglacial recolonization of northern Europe supposedly originated from Western Europe and the Russian Plain, however, recent molecular and macrofossil-based investigations suggest that the history may be more complex than previously thought. This study aims to investigate the genetic diversity and population structure of Scots pine from Scandinavia to Russia to re-evaluate its recolonization history, and to examine whether the pattern of spatial genetic diversity has any adaptive significance.
