Multivariate NIR Studies of Seed-Water Interaction in Scots Pine Seeds (Pinus sylvestris L.)
Lestander, T. A. 2003. Multivariate NIR studies of seed-water interaction in Scots pine seeds (Pinus sylvestris L.). Doctoral dissertation. This thesis describes seed-water interaction using near infrared (NIR) spectroscopy, multivariate regression models and Scots pine seeds. The presented research covers classification of seed viability, prediction of seed moisture content, selection of NIR w...
متن کاملReversibility of Dimensional Changes in Birch (Betula Pubescens) and Scots Pine (Pinus Sylvestris L.) Wood
The reversibility of wood shrinkage through swelling of birch (Betula pubescens) and Scots pine (Pinus sylvestris L.) as a measure of their response to changing conditions of adsorption and desorption during service was determined. Virtually all dimensional changes that occurred in the form of shrinkage during drying at both conventional and high temperatures were recovered during swelling in b...
متن کاملChanges in the essential oil composition in the needles of Scots pine (Pinus sylvestris L.) under anthropogenic stress.
Unfavorable anthropogenic factors, such as air pollution, lead to biochemical responses in trees. Changes in the amounts of secondary metabolites may be early indicators of invisible injuries. The aim of this study was to evaluate composition of the essential oils in the needles of Scots pine (Pinus sylvestris L.) growing in the areas affected by pollutant emissions of main factories in Lithuan...
متن کاملFungal Infection Increases the Rate of Somatic Mutation in Scots Pine (Pinus sylvestris L.).
Somatic mutations are transmitted during mitosis in developing somatic tissue. Somatic cells bearing the mutations can develop into reproductive (germ) cells and the somatic mutations are then passed on to the next generation of plants. Somatic mutations are a source of variation essential to evolve new defense strategies and adapt to the environment. Stem rust disease in Scots pine has a negat...
متن کاملBiochemical and structural characteristics of Scots pine (Pinus sylvestris L.) in an alkaline environment
Investigations in a 7585-year-old Scots pine stand were performed on a territory influenced over 40 years by alkaline dust pollution (pH 12.312.7) emitted from a cement plant. Sample plots were located at distances of 2, 3, and 5 km E of the emission source and a control sample plot was selected on an unpolluted territory 38 km W of it. We studied soil properties and the anatomical structure,...
