Abstract:
... This paper analyses long-term (1960–2015) onset of flowering in 16 native terrestrial plants (11 of them produce important allergens) recorded in different parts of the Czech Republic (southern, central and northern part) in relation to the North Atlantic Oscillation (NAO) index of the preceding winter and thermal data—growing degree-days (GDD) and soil temperature. Flowering occurred significantl ...

Abstract:
... PURPOSE: The aim of the study was to estimate how the deadwood of different tree species in various stages of decomposition affected nutrient dynamics. MATERIALS AND METHODS: The deadwood of eight species (common alder, common aspen, common ash, silver fir, pedunculate oak, Norway spruce, common hornbeam and silver birch) was selected. Three logs from each species in the third, fourth and fifth de ...

Subject:
Alnus; Betula pendula; aboveground biomass; afforestation; agricultural land; biomass production; hybrids; trees; Estonia
Abstract:
... Several studies about stands growing on abandoned agricultural lands are induced by extensive afforestation of agricultural lands and more intensive use of biomass. Overview of above-ground biomass production of grey alder, hybrid alder and silver birch young stands growing on former agricultural areas are presented in current paper. The results of 16- and 6-year period of alders and silver birch ...

Abstract:
... The ability of Frankia strains to grow in the rhizosphere of a nonactinorhizal plant, Betula pendula, in surrounding bulk soil and in soil amended with leaf litter was analyzed 6 weeks after inoculation of pure cultures by in situ hybridization. Growth responses were related to taxonomic position as determined by comparative sequence analysis of nifH gene fragments and of an actinomycetes-specific ...

Abstract:
... Many changes have occurred over the last 70 years: broadleaves no longer exceed conifers in area and coppice has declined markedly. While we see many neglected woods, especially on farms, the depressingly poor quality of much oak which Guillebaud laments is not now viewed so seriously. Today, broadleaves are grown for a wider variety of objectives and not just for fine timber. While excellent stem ...
