“…The MOE result for Douglas fir does not achieve the values stated by Alden [30] at any of the sites. The value from the forest land only comes close to the data for the Douglas fir from the area of the Interior South: 10,300 MPa.…”

“…The evaluated Douglas fir wood does not achieve any of the values from the areas of the original expansion stated by Alden [30], regardless of site. Likewise, the spruce and pine exhibited lower values compared to the literature [32]: 78 MPa and 80 MPa.…”

“…Alden [30] specifies the highest value for coastal Douglas fir of 0.570 g·cm −3 for each area of the original extension. Our results correspond to this value (regardless of the site), and in terms of density, this is very high quality wood, and these are fairly young trees that have not yet reached rotation age, and we can assume that the density will increase.…”

This study compares the quality of wood from two distinct sites in the Czech Republic-from former afforested agricultural land and forest land. We compared the properties of Norway spruce wood (Picea abies Karst.) and Scots pine wood (Pinus sylvestris L.), the most important domestic tree species, to Douglas fir (Pseudotsuga menziesii (Mirbel) Franco), a North American tree species and a potential substitute for the domestic spruce. Wood density, modulus of elasticity (MOE), modulus of rupture (MOR) and impact bending strength were the properties tested that were used for comparing tree species. Without taking into consideration the site, the highest density values from the tested tree species were obtained for Douglas fir (0.568 g·cm −3 ), followed by the pine (0.508 g·cm −3 ) and the spruce (0.463 g·cm −3 ). The Douglas fir also dominated in the remaining assessed properties, whilst the influence of site was not confirmed, with the exception of MOE and MOR, and only for the Douglas fir wood, wherein higher values were obtained for forest land. In terms assessed Douglas fir properties, it exceeds the domestic softwoods and represents a possible suitable replacement for them. The site only plays a role in terms of the Douglas fir, and only for certain properties.

“…The natural habitat of Grand fi r is the Northwest coast of North America. The climatic conditions in its natural habitat range from mild maritime to downright continental climate (Foiles et al, 1991;Alden, 1997;Klinka, 2007). Grand fi r is considered in the Central European region to be a prospective introduced tree species.…”

“…Při opracování a lepení nevznikají vzhledem k chybějícím pryskyřičným kanálkům větší problémy (Vos & Kharazipour 2010). Hustota dřeva v rámci přirozeného areálu v Severní Americe dosahuje kolem 370 kg.m −3 (Alden 1997;Green et al 1999), zatímco v ČR je v průměru o něco vyšší, a to 405 kg.m −3 (Lukášek et al 2012). Objemová hmotnost je v důsledku rychlého růstu projevujícího se malým podílem pozdního dřeva a velkým (0,54 cm) tloušťkovým přírůstem nízká (Hofman 1963).…”

The grand fir (Abies grandis /Douglas ex D. Don/ Lindl.) is a promising species with a high potential to fulfil many forest functions, mainly production, site improvement and landscaping functions. The aim of the presented study is to summarise the research results concerning the silviculture of this species, production capacity and environmental effects in the conditions of the Czech Republic. Despite its relatively small reduced area, which was 1,208.59 ha in 2013 (http://eagri.cz), Grand fir shows quite high potential of producing timber convenient for specific purposes, and has a favourable effect on forest soils. At specific favourable sites it is superior also to Douglas-fir. It has a considerable potential for ornamental purposes and as a Christmas tree. Basic knowledge for its successful cultivation is available.Key words: Grand fir; production; silviculture; ecological effects; timber use abstrakt Jedle obrovská (Abies grandis /Douglas ex D. Don/ Lindl.) představuje dřevinu s potenciálním přínosem pro plnění řady funkcí v lesním hospodářství, zejména funkce produkční, meliorační, stabilizační a krajinářská. Cílem příspěvku je sumarizace výsledků týkajících se pěstování, produkčního a environmentálního významu této dřeviny v podmínkách České republiky. Přes poměrně malou redukovanou plochu, která v roce 2013 činila 1208,59 ha (http://eagri.cz), vykazuje tato dřevina značný produkční potenciál specificky využitelného dříví a příznivý meliorační vliv na vlastnosti lesních půd. Na pro ni příznivých stanovištích dokáže předstihnout i douglasku tisolistou. Nezanedbatelný není ani její význam z hlediska produkce ozdobného klestu a vánočních stromků. Pro její úspěšné pěstování jsou k dispozici základní podklady.
