21. Effect of high-temperature drying on spruce and larch Shape stability, mechanical properties and mould growth
Abstract : Shape stability, the ability of the wood to retain its shape, is one of the most important parameters when using timber as a building material and for other applications. Generally, timber undergoes changes in dimensions and shape when its moisture content is changed. READ MORE

22. Population Genetics and Genome Organization of Norway Spruce
Abstract : Understanding the underlying genetic causes of adaptation to local conditions is one of the main goals of population genetics. A strong latitudinal cline in the phenotypic trait of bud set is observed in present day populations of Norway spruce (Picea abies (L.) Karst). READ MORE

23. Interactions between calcium and heavy metals in Norway spruce : Accumulation and binding of metals in wood and bark
Abstract : Waste products from the forest industry are to be spread in forests in Sweden to counteract nutrient depletion due to whole tree harvesting. This may increase the bioavailability of calcium (Ca) and heavy metals, such as cadmium (Cd), copper (Cu) and zinc (Zn) in forest soils. READ MORE

24. Genetics, breeding and deployment of Melaleuca and Norway spruce
Abstract : Additive effects of genes are cumulative over generations and are the main source of genetic variation exploited by most plant breeding programs. However, the relative importance of additive and non-additive genetic effects is critical information required to properly evaluate the potential for genetic gain from various breeding programs and deployment options used in the genetic improvement of forest trees.

25. Volatiles of Conifer Seedlings : Compositions and Resistance Markers
Abstract : Pine weevils cause major damage to newly planted conifer seedlings in reforestation areas. However, recent findings indicate that small (“mini”) seedlings, planted at the age of 7-10 weeks, are gnawed less by pine weevils than the larger, conventionally planted seedlings. READ MORE
