Silver fir is one of the longest living and tallest trees in Europe, it has major commercial importance and may be found in various communities predominantly connected with lower mountainous locations...
The simple sequence repeats (SSR) method of DNA analysis was used to determine genetic diversity within and among silver fir (Abies alba Mill.) populations. Total genomic DNA was extracted from 250 Ab...
In the second half of 20th century silver fir regeneration has been observed throughout all of the Europe, including the Czech Republic. The Bohemian Forest – Šumava Mts. is one of the regions wh...
The variation of the morphological characteristics and internal structure of silver fir (Abies alba Mill.) seeds from 4 stands growing at the altitude of 625?50 m in the Beskid S筪ecki and Beskid Niski...
The silver fir was planted under mountain conditions in order to reveal its response to the addition of finely ground rocks (limestone and amphibolite) mixed with soil into the planting holes. The res...
The main task of the study was to investigate the growth conditions of silver fir natural regeneration in the Karkonosze Mts. (Poland). The paper examines the quantity and quality of light reaching th...
Silver fir as a domestic species is an important tree in our forests. Unfortunately it has suffered from serious dieback in Central Europe in the last decades. Reintroduction of Silver fir is not an e...
The objectives of this study are to determine the progress of the development cycle of the forest taking into account untypical development periods caused by fir decline and recovery, and to compare t...
In the growing season 2001 changes were studied in the diameter increment of selected sample trees of silver fir and beech in a mixed stand using mechanical girth dendrometers. Within the selected set...
This paper reports the physico-chemical characteristics of the products derived from the thermolysis (thermolytic distillation) of waste silver fir (Abies alba Mill.) wood at different temperatures (4...
In 10 silver firs (Abies alba), the following was investigated: anatomical structure of phloem growth rings (FB) in relation to their width, ratio between number of cell-layers in FB and in xylem grow...
We analysed the characteristics of silver fir (Abies alba Mill.) occurrence and distribution in Slovenia using databases of the Slovenian Forest Service (SFS). Silver fir is the third most widely dist...
The dynamics of xylem and phloem growth ring formation in silver fir (Abies alba Mill.) was studied during the growing season 2003. Blocks of tissue, containing phloem, cambium and outer xylem, were t...
To examine the state of differentiation of the last tracheids formed in wood and the duration of cambial activity, samples of wood and cambium were taken from mature silver fir (Abies alba) trees havi...
Volatile profiles of lime tree (Tilia sp.), fir honeydew (Abies alba) and sage (Salvia officinalis) honey produced in Croatia have been studied by using headspace solid phase microextraction (HS-SPME)...
