We study the restoration of coal mining dumps through reforestation in forest-steppe zone Kuzbass. 3 main forest-forming species ( Betula pendula, Pinus sylvestris and Populus tremula ) 11 accompanying tree were involved formation forest stands. The was pendula . amount renewal found to be 10.7, 3.1 1.0 thousand pcs/ha sites with favourable, moderate favourable unfavourable environmental condit...

Background In the Romanian flora, several species of the Betula genus are present, especially European white birch (B. pendula, syn. B. verrucosa) and downy birch (B. pubescens, syn. B. alba). Rare species are B. nana and B. humilis. In Southern Romania, the sensitization to Betulaceae pollen in patients with allergic rhinitis is less frequent than that to Poaceae pollen. The flowering season o...

(1) Elevated atmospheric CO2 (eCO2) may affect organic inputs to woodland soils with potential consequences for C dynamics and associated aggregation; (2) The Bangor Free Air Concentration Enrichment experiment compared ambient (330 ppmv) and elevated (550 ppmv) CO2 regimes over four growing seasons (2005–2008) under Alnus glutinosa, Betula pendula and Fagus sylvatica. Litter from the experimen...

Variation of colour and selected physical and mechanical properties related to artificial drying of sawn silver birch (Betula pendula Roth) timber from plantations. ...

Quantitative and qualitative lignin analyses were carried out on material from the trunks of silver birch (Betula pendula Roth) trees. Two types of material were analyzed. First, whole birch trunk pieces were cryosectioned into cork cambium, non-conductive phloem, the cambial zone (conductive phloem, cambium and differentiating xylem), lignified xylem and the previous year's xylem; material tha...
