Serbian spruce, a narrow endemic, contains much genetic variation

Canadian Journal of Forest Research, 1991
Serbian spruce (Piceaomorika (Pančić) Purk.) is reputedly a self-fertile and morphologically uniform species with a natural distribution restricted to a total area of less than 60 ha in central Yugoslavia. This has led to the conclusion that the species lacks genetic variation. In this study, genetic variation at 19 enzyme loci was investigated in two

Genetic structure of a rare European conifer, Serbian spruce (Picea omorika (Panč.) Purk.)

Plant Systematics and Evolution, 2006
Genetic variation in 13 populations of a Balkan endemic, Serbian spruce (Picea omorika (Pancˇ .) Purk.), was investigated using 16 isozyme loci. Serbian spruce is characterized by low levels of genetic variation (average proportion of polymorphic loci was 20.9% and average expected heterozygosity was 0.067).

Needle oil terpenes of Serbian spruce from three localities

Holz als Roh- und Werkstoff, 1993
The volatile oils from needles of Serbian spruce from two localities in Serbia outside of the native range and one locality from Germany (Hamburg) were determined to have the same terpene pattern, with bornyl acetate as the major component.

Variability of antioxidant enzyme activity and isoenzyme profile in needles of Serbian spruce (Picea omorika (Panč.) Purkinye)

Biochemical Systematics and Ecology, 2007
Abstract Variations were studied of the activity and isoenzyme patterns of soluble peroxidase, catalase, catechol oxidase and superoxide dismutase, in needles of the Balkan endemic conifer Serbian spruce, Picea omorika (Panc.) Purkinye. The samples were collected from the natural habitat of the species, Mt. Tara.

Relations of cell wall bound peroxidases, phenols and lignin in needles of Serbian spruce Picea omorika (Pančić) Purkynĕ in the natural habitat

Biochemical Systematics and Ecology, 2015
The habitat of Picea omorika (Pancic) Purkynĕ, Serbian spruce, is characterized by extremely variable environmental conditions. Relations between the activities of cell wall bound peroxidase (POD) and contents of lignin and cell wall bound phenols were studied in needles of Serbian spruce, in the natural habitat on Mountain Tara. We intended to see, by

Phenolic acids distribution in a peat of the relict community with Serbian spruce in the Tara Mt. forest reserve (Serbia)

European Journal of Soil Biology, 2003
Restoration of tertiary endemorelict Serbian spruce (Picea omorika Pancic) in forest-peat in Tara Mt., the only such finding in the world is rather poor. This could be partially ascribed to the presence of phenolics in peat soil. Content of total phenols and phenolic acids was determined in peat samples taken from: (1) knolls of forest-peat bog with ...

Serbian Spruce is as Vulnerable as Sitka Spruce to Damage by the Sitka Spruce Weevil

Western Journal of Applied Forestry, 1992
Abstract Serbian spruce (Picea omorika) was first damaged naturally by the Sitka spruce weevil (Pissodes strobi) at about 15 years of age in an area on Vancouver Island where this weevil commonly attacks Sitka spruce (Picea sitchensis).

Transversal stress wave velocity in the tree of Serbian spruce (Picea omorika (Pančić) Purkyně)

Sustainable Forestry: Collection, 2022
In this paper, transversal stress wave velocity was measured in 30 trees of Serbian spruce (Picea omorika /Pančić/ Purk.) using a 2D sonic tomograph. Tomograms were analyzed and speed loss and average speed for Serbian spruce were calculated. Since there is no reference value for this species, in this research the reference value for stress wave ...
