| Description
| - Stem wood density (SWD) of young Norway spruce trees (Picea abies [L.] Karst.) growing at ambient (A variant, 350 mikromol(CO2)mol-1) and elevated (E variant, A+350 mikromol(CO2)mol-1) atmospheric CO2 concentration inside of the glass domes with adjustable windows was estimated after six and eight years of the cultivation. Stand density of two subvariants (s - sparse with ca 5.000 trees/ha and d - dense with ca 10.000 trees/ha) and thinning impact (intensity of 27%) on SWD and its variation along the stem vertical profile were investigated. After six years of CO2 fumigation, stems of sparse subvariant had about 10% lower values of SWD comparing to dense ones, although the difference was not statistically significant. In 2004 (two years after thinning), the SWD values were higher in all subvariants along the whole stem vertical profile. This increase was more obvious in E variant (about 6% in d subvariant and only 3% in s subvariant). The highest increase of SWD values was found in Ed subvariant, par

- Hustota dřeva kmene (SWD) byla stanovena u mladých jedinců smrku ztepilého (Picea abies [L.]) kultivovaných po dobu šesti a osmi let v přirozené (varianta A, 350 mikromol(CO2)mol-1) a zvýšené (varianta E, A+ 350 mikromol(CO2)mol-1) vzdušné koncentraci CO2 uvnitř lamelových komor. Zkoumán byl vliv rozdílných hustot porostu (sub-varianty: s- řídká 5tis. ks.ha-1 a d- hustá 10tis. ks.ha-1) a prořezávky (intenzita 27%) na SWD a jeho změny v podélném profilu kmene. Po šesti letech fumigace CO2 byly hodnoty SWD kmenů řídké sub-varianty v průměru o 10% nižší ve srovnání s hustou sub-variantou. V r. 2004 (dva roky po pro5ez8vce) byla SWD kmenů výší podél celého profilu kmene ve všech sub-variantách. Tento nárůst byl výrazný především ve variantě E (v průměru o 6% v husté sub-variantě a o 3% v řídké). K nejvyššímu nárůstu hodnot SWD kmenů husté sub-varianty E došlo ve střední části kmene (o 8%, statisticky průkazný rozdíl). (cs)
