11. Analysis of plant growth regulating substances
Sammanfattning : Natural plant growth regulators (phytohormones) are a group of organic compounds which, in very small amounts, act as regulators of physiological processes in plants.Methods were developed for the analysis of phytohormones in samples from Norway spruce (Picea abies (L.) Karst.) and Scots pine (Pinus sylvestris (L. LÄS MER
12. Process development and environmental assessment within softwood based biorefineries
Sammanfattning : We urgently need to move from a fossil-based to a bio-based society. From a Swedish perspective, a promising way forward are biorefineries with an integrated production of materials, chemicals, and energy from the softwood species Scots pine (Pinus sylvestris) and Norway spruce (Picea abies).

13. Prediction of wood species and pulp brightness from roundwood measurements
Sammanfattning : This thesis presents a number of studies, where a multivariate approach was taken to construct models that predict wood species and thermo mechanical pulp brightness from roundwood of Norway spruce and Scots pine. The first and second studies produced multivariate prediction models for wood species from the bark of spruce and pine. LÄS MER
14. Holocene climate change and peatland dynamics in southern Sweden based on tree-ring analysis of subfossil wood from peat deposits
Sammanfattning : Dendrochronological analysis was applied to subfossil remains of Scots pine (Pinus sylvestris L.) buried in South Swedish peat deposits. LÄS MER
15. Game of crops : genetic composition and adaptation of seed orchard crops
Sammanfattning : Orchard populations are artificial and intensively managed populations of elite, best-performing trees that are established for mass production of genetically improved seeds. Seed orchards connect cycles of selection, breeding, and testing of plus-trees with the deployment of the improved seeds at the operational plantations. LÄS MER
