15 صفحه اولChanges 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 کاملTensile test on pine needles and crack analysis of pine needles short fiber reinforced composites
Natural fibers are widely used as reinforcing material in composites. Pine needles can be used as natural fibers which are abundantly found in the hilly areas of India. A study on tensile test of pine needles and the crack analysis of pine needles short fiber reinforced composites has been presented in this paper.ASTM D638-10 standard is followed for tensile testing and a number of specimen is ...
متن کاملPartitioning of carbohydrates and biomass of needles in Scots pine canopy.
The study was aimed at the quantitative evaluation of the temporal and spatial partitioning of non-structural carbohydrates and needle biomass in a canopy of Scots pine (Pinus sylvestris L.) growing in a Myrtillus site type forest stand (predominant in Estonia). The tree canopy was divided into ten equal layers and the material for the spatial partitioning of the investigated characteristics wa...
