Pollen competition and seed-siring success in Picea abies
Theoretical and Applied Genetics, 2002The aim of the present work was to study pollen-tube competition in Picea abies. Controlled crossings were performed with pollen mixtures including pairs of pollen lots with fast and slowly elongating pollen-tubes. Paternity analysis using isozyme markers was performed on the progenies in order to study whether the in vitro pollen-germination vigour ...

Transformation of terpenes using a Picea abies suspension culture
Journal of Biotechnology, 2004When subjected to a Picea abies suspension cell culture, beta-pinene, either one of the pure enantiomers or the racemate, was transformed mainly to trans-pinocarveol along with the minor products myrtenol, alpha-terpineol, pinocarvone, myrtenal and cis-pinocarveol.

An acetylated galactoglucomannan from Picea abies L. Karst
Carbohydrate Research, 2002A water-soluble galactoglucomannan composed of D-galactose, D-glucose, and D-mannose in 1:3:17 mole proportion has been isolated from the secondary cell walls of Picea abies L. Karst. About 33% of the polysaccharide units were substituted by acetyl groups.

Rhizina undulata on Picea abies transplants
Forest Pathology, 1977At 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.

Fertility and viability of Picea abies (L.) Karst. pollen in the arboretum of the Donetsk Botanical Gardens were studied. In the low cone year (2004) for P. abies its pollen fertility made up 63% and its viability made up 56%. Various trees showed significant individual variability of the given indices. The length of the pollen tubes from various trees

Rapid yellowing of needles of Picea abies
European Journal of Forest Pathology, 1989AbstractSevere chlorosis developed in a 45 year old stand of Norway spruce over a period of three weeks in July and August 1986. The chlorosis was followed by needle necrosis and, eventually, shedding. The trees showing the most severe effects had all been damaged during timber extraction operations in 1985.
