Distinguishing root- and stem-wood of Picea Abies

IAWA Journal, 2011
In archaeology, palaeobotany and dendrochronology, it can be important to distinguish between root- and stem-wood. Although numerous studies have described the root-wood of various species in great detail, there is, as yet, no quick and generally accepted wood anatomy-based method to distinguish Norway spruce root- from stem-wood.

Rhizina undulata on Picea abies transplants

Forest Pathology, 1977
At least three quarters of the sites of brash fires in a mainly coniferous area on peat in Co Tyrone, Northern Ireland were clonised by Rhizina undulata. On each of these sites an average of eight newly planted Picea abies died within five years. No more deaths were recorded during a further three years.

Norway Spruce (Picea abies (L.) H.Karst.)

2013
Norway spruce (Picea abies (L.) Karst.) is one of the most important coniferous species in Europe both from an economic and ecological point of view. Solid wood products and pulp and paper products have the largest economic value. The patterns of variation observed in Norway spruce provenance trials show geographic variability on a large scale.

Norway Spruce Picea abies (L.) Karst

2018
The increasing use of wood as a source of bioenergy, bio-products and conservation of more natural (old) forests with high biodiversity, compel us to find means to increase forest productivity. Using the best quality regeneration material can increase the economic gain obtained from future silvicultured forests.

Izolacija protoplasta iz pupova Picea abies

1986
O izolaciji protoplasta četinjača nije objavljeno mnogo radova. U predstavljenom eksperimentu postupak izolacije protoplasts iz pupova vrste Picea abies uključivao je sakupljanje, površinsku sterilizaciju i izolaciju dostatnog broja pupova da bi se imalo dovoljno svježe tvari za enzimski tretman. Postupak izolacije protoplasta ponavljan je četiri puta.
