    Sammanfattning : The convergence of quantitative genetics of complex traits with genomic technologies is quickly becoming an innovative approach to explore fundamental genetic questions and also have practical consequences for implementations in tree breeding. In this thesis, I used genomic selection and genome-wide association studies (GWAS) to dissect the genetic basis of quantitative traits, i. LÄS MER

  3. 2. Applications of molecular characters to breeding of Eucalyptus urophylla in Vietnam

    Författare :Tran Ho Quang; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The aim of this study was to investigate how to incorporate molecular genetics into the tree breeding program for E. urophylla. The material was a combined provenance and progeny trial, initially including 144 families from open-pollinated trees of nine provenances. LÄS MER

  4. 3. Study on the structure and properties of xylan extracted from eucalyptus, sugarcane bagasse and sugarcane straw

    Författare :Danila Carvalho; Mikael Lindström; Åsa Emmer; Sverker Danielsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Lignocellulosic biomasses are an important source of chemical components such as cellulose, lignin and hemicelluloses, and can be used for a variety of purposes in both the pulp and paper and chemical conversion industries. Xylan, the main hemicellulose found in hardwood and grass plants, plays an important role during the pulping/pretreatment process reactions, including those used in 2nd generation bioethanol production.

  5. 4. Carbohydrate degradation and dissolution during Kraft cooking : Modelling of kinetic results

    Författare :Dan Johansson; Ulf Germgård; Pedro Fardim; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kraft cooking; softwood; hardwood; cellulose; xylan; glucomannan; degradation; dissolution; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : Chemical pulp fibres from wood are commonly used in products associated with packaging as well as with printing and writing. The prevalent way of liberating fibres is by subjecting wood chips to Kraft cooking. This process has a history of almost 130 years and should be both well described and well established. LÄS MER
