Picea abies; Pinus sylvestris; absorption; biodegradation; climate; desorption; dimensional stability; drying; environmental factors; fiber saturation; glulam; hydrophobicity; hygroscopicity; microbial growth; microorganisms; oils; relative humidity; temperature; water content; wood; wood moisture
Abstract:
... In order to survive, the wood degrading microbes need a moisture content of wood exceeding the fibre saturation point, i.e., 26%–32%, depending on the species. Maintaining wood moisture content below this level effectively prevents biodegradation. This can be achieved either by preventing wood's exposure to liquid water or increasing the hydrophobicity of wood by some impregnation or modification ...

Picea abies; Raman spectroscopy; biodegradation; branchwood; cell wall components; cell walls; cellulose; hemicellulose; lignin; solvents; sugars; transmission electron microscopy
Abstract:
... Wood is a naturally occurring composite, comprising cellulose, hemicellulose, and lignin. The tightly arranged cell wall components make the fibers resistant against chemical and microbial degradation. This natural resisting power of fibers is a technical obstacle during the degradation of cellulose into sugars. Therefore, removal of cell wall lignin is necessary in order to make the cellulose acc ...

Abstract:
... European larch (Larix decidua Mill.) and Norway spruce [Picea abies (L.) Karst.] synthesize chlorophyll (Chl) in darkness. This paper compares Chl accumulation in 14-d-old dark-grown seedlings of L. decidua and P. abies after shortterm (24 h) feeding with 5-aminolevulinic acid (ALA). We used two ALA concentrations (1 and 10 mM) fed to cotyledons of both species in darkness and in continuous light. ...

Abstract:
... Traditionally forest resources are estimated in each compartment or stand with ocular standwise forest inventory. However, this inventory technique has shortages with measurement accuracy. In the study the accuracy of the standwise forest inventory was estimated by comparing the growing stock volume of the standwise inventory with the accurate (instrumental) re-measurements. Comparison was done wi ...

Thinning of forest stands by selective tree removal is a common tool in forest management that increases light intensity. However, morphological and anatomical adaptations of individual shoots to the new environmental conditions created by thinning are still poorl ...

Abstract:
... The most efficient way to obtain stand inventory data with terrestrial laser systems (TLS) is with the single-scan mode, which involves taking one scan at a single point. With a single-scan setup, there will be a nondetection of trees in a plot and the representation of the individual trees will be incomplete. We explore how stand-level volume estimates, based on the single-scan mode, perform comp ...

Background and AimsWoody plants can suffer from winter embolism as gas bubbles are formed in the water-conducting conduits when freezing occurs: gases are not soluble in ice, and the bubbles may expand and fill the conduits with air during thawing. A major assumption usually made in studies of winter embolism formation is that all of the gas dissolved in the xylem sap is trapped within the conduit ...
