Stem discoloration of planted silver birch

Scandinavian Journal of Forest Research, 1998
The spread of discoloration in planted silver birch (Betula pendula Roth.) stems was investigated in 137 stands in Finland and the role of microbes was investigated in 71 stands. The colour changes noted in the pith of planted silver birches (18–65 years old) were very common but restricted and did not show unacceptable quality or reduction in veneer ...

Differentiating Curly Birch from Silver Birch by Ultrasound

AIP Conference Proceedings, 2007
Curly birch (CB, Betula pendula var. carelica) commands a 10x higher price than silver birch. For thinning purposes it is crucial to differentiate between the two types as early as possible. We studied the possibility to use ultrasound for this differentiation. The propagation velocity of 4 MHz longitudinal ultrasonic 5‐cycle bursts transmitted through

Computerized ultrasound differentiation of curly birch from silver birch

Journal of Applied Physics, 2007
We report on computerized differentiation of two birch types. Curly birch (CB, Betula pendula var. carelica Sok) commands a higher price than a normal silver birch (SB, Betula pendula Roth). Hence it is crucial to differentiate the two wood types when the trees are young. We studied the possibility to use ultrasound for such differentiation.

Boron uptake by ectomycorrhizas of silver birch

Mycorrhiza, 2004
Boron (B) is an essential micronutrient for plants but it is thought not to be essential for fungi. We studied whether the extraradical mycelia of Paxillus involutus in symbiosis with silver birch (Betula pendula) take up B and transport it to the host plant.

Bacterial Diseases of Silver Birch (Betula pendula Roth.)

Mikrobiolohichnyi Zhurnal, 2020
A significant role in the pathogenesis of diseases of woody plants belongs to phytopathogenic bacteria and fungi. It has been scientifically confirmed that the organs and tissues of woody plants have a certain myco- and microbiota, the components of which are systematically interconnected both with each other and with the plant. The species composition

Silver birch telomeres shorten in tissue culture

Tree Genetics & Genomes, 2013
Shortening of telomeres has been connected with ageing and loss of cell replication or regeneration capacity. The aim of the present study was to examine potential variation in the length of telomeric repeats in silver birch (Betula pendula Roth) using clonal materials consisting of different-aged outdoor trees and tissue cultures of seven genotypes ...

Boron Fertilization Enhances the Induced Defense of Silver Birch

Journal of Chemical Ecology, 2011
Boron (B) deficiency is a common micronutrient deficiency that has been reported to affect the phenolic metabolism of plants. Thus, it may play a role in defense against herbivorous animals. However, the role of B in a plant's resistance to herbivores has not received any particular attention from researchers.

Allergic Contact Dermatitis from Silver Birch Pollen

1989
A 32-year-old housewife and schoolteacher presented annually from 1983 to 1986 with a seasonal April-to-September dermatitis of the exposed skin of her face, neck, and limbs, with extreme swelling of the eyelids. Her dermatitis was most severe at home, where it was not prevented by staying inside. It was improved by continuous rain, holidays by the sea,

Within-stand variation in silver birch (Betula pendula Roth) phenology

Trees, 2014
Within a local population genotypes differ in the timing of bud burst, but genotypes with early bud burst unfold their leaves slower, resulting in an equal period of carbon gain. The ability of local populations to cope with disturbances like adverse weather events or a changing climate depends on the genotypic richness of such ...
