To evaluate the effects of nano priming on seed germination of Alnus subcordata (Caucasian alder) C.A. von Meyer under drought stress, the present research was conducted using multi-walled carbon nano...
The role of plant roots in stabilizing slopes is obvious, but the amount of the effect is varied in different species. The purpose of this study was to evaluate the effect of alder (Alnus subcordata) ...
Phytophthora alni is responsible for a devastating disease in alder and changes in the environment of riparian and alder carr ecosystems. One of the main approaches to solve this problem is to find na...
An experiment with seedlings of Alnus viridis was established on a clear-felled tract situated on a summit tableland of the Jizerské hory Mts. (central Europe, Czech Republic) at an altitude of 980 m ...
A young speckled alder (Alnus incana [L.] Moench) stand was planted on a tract clear-felled due to air pollution and located on a summit plateau of the Jizersk?hory Mts. (Central Europe, Czech Republi...
Variation of metric and qualitative characteristics of A. incana (L.) Moench. and A. glutinosa (L.) Gaertn. has been studied in 10 natural populations in West Siberia, Russia and the Czech Republic in...
The present study documents the effects of green alder [Alnus alnobetula (Ehrh.) C. Koch] on the uppermost forest soil layers in mountain areas, respectively in the summit part of the Jizerské hory Mt...
The objectives of this paper are to ascertain the main factors involved in the phenological mechanism of alder flowering in Central Europe by understanding the influence of the main meteorological par...
To examine the potential of Alnus faurei for use in revegetation of disturbed steep hillsides, its growth and tree form were compared to those of traditionally used species: A. maximowiczii and A. hir...
The objective of this study is to estimate the stem volume per single tree for Alnus glutinosa Gaertn subsp. barbata (C.A. Mey.)Yalt. stands of East The Blacksea Region. Double Entry Volume Table was ...
In this study, physical properties of Alder Wood [Alnus glutinose subsps. barbata (C.A.Mey.)Yalt.] were investigated. 10 trees used for experiments were obtained from Rize-Çayeli region and sam...
The objective of this study was to estimate biomass per tree for Alnus glutinosaGaertn. subsp. barbata(C. A. Mey.) Yalt. stands in the east Black Sea region of Turkey, Dry-weight tables constructed by...
In this study, some mechanical properties of Alder [Alnus glutinosa subsp. barbata (C. A. Mey.) Yalt.] wood were investigated. The experiments were carried out on test specimens obtained from 10 selec...
In this study, Alder (Alnus glutinosa subsp.Barbata) wood was used for particleboard manufacturing. The purpose of this study was to determine the effects of particle moisture content, shelling ratio ...
Daily average Alnus pollen counts (1996-2005) from Worcester (UK) and Poznań (Poland) were examined with the aim of assessing the regional importance of Alnus pollen as an aeroallergen.
