In the Nordic region, two thirds of a sawmill's turnover is being paid to the forestry sector to obtain adequate roundwood supply. As a consequence, an efficient use of each single log is mandatory for a profitable sawmill. This article discusses a few aspects of this task.

While the release of organic acids from plants may offer a protection against rhizotoxic Al, the efficiency of this mechanism will be reduced by the rhizosphere microbial community

DyDOC identifies three soil horizons with different properties. Within each horizon the transport of wter, metabolic transformations of organic matter, and sorption of potential DOC are simulated. The model is parameterised by fitting experimental laboratory and field data, including 14C signals. The outputs are quasi-steady state C pools, varying on long timescales (centuries) and daily DOC concentrations and fluxes.

Peroxidases constitute a large family of proteins found in all higher plants. Owing to the complexity of the peroxidase isoenzyme family it has been difficult to assess the precise function of individual peroxidase enzymes.In this work we have studied the effects of an endogenous peroxidase-like gene from Norway spruce [Picea abies (L.) Karst], spi 2, on the development and growth of Norway spruce somatic embryo plants.Embryogenic cells of Norway spruce transformed with spi 2 under control of the maize ubi-1 promoter showed up to 40 times higher total peroxidase activity than the control cells; regenerated plants overexpressing spi 2 showed an increased total peroxidase activity.Based on these results and the overall sequence similarity with cationic peroxidases we conclude that spi 2 encodes a peroxidase. Overexpression of spi 2 resulted in increased sensitivity to stress, leading to a reduction in epicotyl formation and in height growth compared with control plants. The plants overexpressing spi 2 also showed a deeper phloroglucinol staining but similar levels of Klason lignin.
