Nutrient dynamic of Norway spruce (Picea abies (L) Karst) litter mixed with litter of Beech (Fagus orientalis lipsky), Alder (Alnus subcordata C.A.Meyer) and Maple (Acer velutinum Boiss.) in pure Norway spruce plantation of Lajim site [PDF]

open access: yesتحقیقات جنگل و صنوبر ایران, 2012
Plant litter decomposition plays an important role in forest soil fertility due to nutrient cycling and soil organic matter formation. Litter decomposition, results in return of leaves nutrient to soil and supply of necessary elements for plant growth ...

Effects of phenotypic selection on height-diameter ratio of Norway spruce and Scots pine in Sweden

open access: yesSilva Fennica, 2018
Genetically improved Norway spruce ( (L.) Karst.) and Scots pine ( L.) are extensively used in operational Swedish forestry plantations. However, relatively little is known about the stem slenderness (height-diameter ratio) of genetically improved ...

Ecological results of Norway spruce forests’ decline in main forest types of the Ukrainian Carpathians

open access: yesНаукові праці Лісівничої академії наук України, 2019
Stationary studies of the decline dynamics on the 21st Norway spruce forest stands in the Ukrainian Carpathians were conducted in 2010-2014. The analysis of the research results made it possible to assess the environmental impacts of their decline for ...

Dynamics of soil organic carbon (SOC) content in stands of Norway spruce (Picea abies) in central Europe

open access: yesiForest - Biogeosciences and Forestry, 2018
Norway spruce is the main forest tree species in the Czech Republic. Until now, little attention has been given in the literature to the dynamics of soil organic carbon (SOC) content under Norway spruce stands as a function of stand characteristics.

Norway spruce postglacial recolonization of Fennoscandia

open access: yesNature Communications, 2022
Contrasting theories exist regarding how Norway spruce recolonized Fennoscandia after the last glaciation. Here, the authors provide evidences from sedimentary ancient DNA and modern population genomics to support that Norway spruce was present in ...

Establishment of Heterobasidion annosum s.l. infections in young Norway spruce dominated stands [PDF]

open access: yes, 2013
One of the worst pathogens on Norway spruce, Heterobasidion annosum s.l., can establish in previously healthy trees by spores landing on freshly made stumps from where mycelia can grow via root grafts and contacts to the adjacent tree.

Transmittance of young Norway spruce stand canopy for photosynthetically active radiation during the growing season

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2013
Analysis of transmittance of young Norway spruce stand canopy for photosynthetically active radiation (PAR) was made at the study site of Bílý Kříž (the Moravian-Silesian Beskids Mts., the Czech Republic) at different sky conditions during the growing ...

The crown condition of Norway spruce and occurrence of symptoms caused by Armillaria spp. in mixed stands

open access: yesJournal of Forest Science, 2020
Mixed stands are currently supported as effective management options to reduce forest vulnerability to climate change. However, our issues about benefits of mixtures, mechanisms of their incidence and conditions for their effectiveness have yet been only
