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).

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.

Individual Variability of Regularity, Abundance and Morphometric Properties of Serbian Spruce(Picea omorika/Panč./Purkyne)Microstrobiles

1998
In Serbian spruce seed orchard Bela Zemlja near Užice (Serbia), 25 test trees were selected as representative. The analysis of microstrobile regularity and abundance indicates the existence of individual variability, both between individuals during one year and between the same individuals in two years of research.

Cryopreservation of embryogenic tissues of Picea omorika (Serbian spruce)

Plant Cell, Tissue and Organ Culture (PCTOC), 2010
Two-year-old embryogenic tissues (ET) of Picea omorika (Pancic) Purk. were successfully cryopreserved after preculture with sucrose, air-drying for 2 h, and freezing in liquid nitrogen (LN). The preculture protocol consisted of passaging the ET onto standard Litvay medium containing increasing concentrations of sucrose (0.25 M sucrose for 24 h, 0.5 M ...

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 ...

Population genetic structure of the relict Serbian spruce, Picea omorika, inferred from plastid DNA

Plant Systematics and Evolution, 2007
We used paternally inherited chloroplast microsatellites (cpSSR) to study population genetic structure in the endemic and highly restricted Serbian spruce Picea omorika. Fragment size polymorphism at the five cpSSR regions that could be amplified out of the nine tested combined into only four different haplotypes in the seven populations studied.

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 ...
