EFFECT OF CADMIUM IONS ON THE GERMINATION OF KARELIAN BIRCH AND SILVER BIRCH SEEDS

Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2020
The effect of cadmium ions (from 10–6 to 10–3 M) on seed germination and early development of seedlings was studied in Karelian birch B. pendula Roth var. carelica (Mercklin) Hämet-Ahti and silver birch Betula pendula Roth.

Long-term wildfire effect on nutrient distribution in silver birch (Betula pendula Roth) biomass

Soil Science Annual, 2022
This study aimed to evaluate the long-term effects of wild fi re on nutrient distribution in a silver birch ( Betula pendula Roth) biomass. Two stands (post- fi re and control) of the same age (27 years) were studied in the Cierpiszewo Forest District ...

Characterization of the Volatile Compounds of the Hardwood Portion of Betula papyrifera Marshall From Quebec, Canada. [PDF]

Chem Biodivers
The volatile profile of Betula papyrifera hardwood has been characterized using both hydrodistillation and HS‐SPME coupled with GC‐MS/FID. Hydrodistillation yields a fatty acid‐rich essential oil, while HS‐SPME reveals a broader range of low‐molecular‐weight volatiles, including aromatics and terpenoids.

Nutrient fluxes via litterfall in silver birch (Betula pendula Roth) stands growing on post-arable soils

European Journal of Forest Research, 2023
The purpose of this study was to evaluate the importance of litterfall as a link in biogeochemical cycling of certain elements (C, N, P, K, Ca, Mg, Fe, Mn, Cu, and Zn) in silver birch stands growing on post-arable soils under temperate climatic ...

Gene regulatory network analysis of silver birch reveals the ancestral state of secondary cell wall biosynthesis in core eudicots. [PDF]

New Phytol
Summary The compact genome and lack of recent whole‐genome multiplication (WGM) events make the boreal pioneer tree silver birch (Betula pendula) a promising model for primary and secondary cell wall (PCW and SCW) regulation in forest trees. Here, we constructed regulatory networks through combined co‐expression and promoter motif analysis and carried ...

THE COMPOSITION OF TOTAL LIPID FRACTIONS AND FATTY ACIDS IN BUDS OF BIRCH SPECIES DURING BUD BREAK

Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2018
In the process of bud break in downy birch Betula pubescens Ehrh., silver birch Betula pendula Roth, and Karelian birch Betula pendula var. carelica Merckl., total lipid (TL) content in buds varied within 27–45 % of absolute dry weight (a. d. w.).
