Ozone-Induced Defense Reactions in Birch (Betula pendula Roth)
1996We have studied the responses of ozone sensitive and insensitive birch (Betula pendula Roth) clones to ozone and analyzed cell death, changes in enzyme activities, metabolite concentrations and gene expression. Cell death, measured by vital stain Evan’s Blue permeability, increased in both clones similarly.

Characterization of a birch (Betula pendula Roth.) embryogenic gene, BP8
Plant Molecular Biology, 1993We have isolated the birch homologue (BP8) for the carrot embryogenic gene DC8 by heterologous hybridization. The birch BP8 gene encodes a putative protein of 53 kDa, showing 52% sequence identity with the DC8 gene at the amino acid level. The putative BP8 protein contains 20 repeats of 11 amino acids and thus belongs to the group of LEA proteins ...

Fibre Length and Microfibril Angle in Silver Birch (Betula pendula Roth)
Holzforschung, 2001Summary A comparative study was carried out on fibre length and microfibril angle in Betula pendula Roth. Fibre length increased and microfibril angle decreased from pith to bark. Microfibril angle remained constant from the 15th annual ring from the pith, to the outermost ring.

Reproductive effort of short shoots in silver birch (Betula pendula Roth)
Experientia, 1988The degree of autonomy was estimated for generative short shoots of silver birch by defoliating them after leaf flush. Defoliation reduced both final length (4%) and weight (18%) of female inflorescences. Short shoots are thus reproductively semi-autonomous modules of silver birch.

Somatic embryogenesis in birch (Betula pendula Roth.)
1995The genus Betula consists of 40–60 species of deciduous trees and shrubs, distributed in the cooler parts of Europe, Asia, and North America. Most species are extremely hardy, some grow at the far north around the Arctic Circle, where they form the northern treeline.

Phytoremediation of zinc contaminated soils using silver birch ( Betula pendula Roth)
Ecological Engineering, 2014Abstract The purpose of this study was to evaluate the usefulness of Betula pendula for the phytoremediation of soils contaminated with Zn. The trees grew on highly contaminated mounds of metallurgical waste under control conditions. The study demonstrated the ability of this species to accumulate high amounts of Zn in its leaves, in both the ...

Carbon budgets in fertile silver birch (Betula pendula Roth) chronosequence stands
Ecological Engineering, 2015Abstract Carbon (C) budgets were compiled for silver birch chronosequence stands by synthesizing the above- and belowground C pools and fluxes with the aim to assess the impact of age on stand C sequestration and cycling. The fine root (d Soil respiration (Rs) was measured during the two growing seasons of 2010 and 2011; the trenching method was ...
