16. Abiotic stress and plant-microbe interactions in Norway spruce
Sammanfattning : Norway spruce (Picea abies) is a dominant tree species in boreal forests with extensive ecological and economic value. Climate change is threatening these ecosystems, with rising temperatures impacting cold hardening and increasing drought stress in regions experiencing lower precipitation. LÄS MER
17. The initial phase of the sodium bisulfite pulping of softwood dissolving pulp
Sammanfattning : The sulfite pulping process is today practised in only a small number of pulp mills around the globe and the number of sulfite mills that use sodium as the base (cation) is less than five. However, due to the increasing interest in the wood based biorefinery concept, the benefits of sulfite pulping and especially the sodium based variety, has recently gained a lot of interest. LÄS MER
18. Structural Modifications in Spruce Wood during Steam Explosion Pretreatment
Sammanfattning : The rising price of petroleum and environmental concerns regarding CO2 emissions have increased interest in alternative renewable resources. Biomass can be considered as an excellent alternative raw material. A biorefinery uses biomass and produces fuel, energy, and valueadded chemicals. LÄS MER

20. Chemical defence in Norway spruce
Sammanfattning : Norway spruce (Picea abies) responds to stress by biosynthesis of chemical substances, which can deter invading insects or pathogens. Some of these substances are volatile and can be emitted to the surroundings while others are accumulated within the tree. LÄS MER
