The effect of pH on the activity of soluble peroxidase in needles of Serbian spruce (Picea omorika (Panč.) Purkinye): application of a mathematical model [PDF]
General Physiology and Biophysics, 2010 We studied the dependence of peroxidase (POD) activity on pH in crude extract of Picea omorika (Panc.) Purkinye needles and in its acidic and basic fractions, obtained by ion exchange chromatography. Nonlinear regression was applied on the activity data with pH as the explaining variable, using the Levenberg-Marquardt algorithm.

Cone and seed variability in Serbian spruce – indicators of population endangerment
Sumarski ListSerbian spruce (Picea omorika (Pančić) Purk., Pinaceae) is a tertiary relict and one of the rarest, most endangered, and protected conifer species in Europe. Alarmingly, many studies report a continuous decline in its population and vitality. In response to this concerning trend, the present research aims to better understand the reproductive potential

General Physiology and Biophysics, 2009 Thermal inactivation of peroxidase (POD) in an extract of Picea omorika (Pancić) Purkyne needles initiated by heat treatment was studied. This is the first study of this kind on a conifer species. Non-linear regression analysis was applied on the inactivation rate data, combining Mitscherlich and Arrhenius equations, treating time and temperature ...

AFRICAN JOURNAL OF BIOTECHNOLOGY, 2012 When considering the effect of heavy metals on trees generally and on forest ecosystems especially, importance is given to their influence on seed germination in metal polluted soil. There is insufficient data on this subject, especially when conifers are concerned. In this work, the influence of high cadmium concentrations on percentage germination,

Provenance Variation in Functional Traits of European Forest Trees: Meta-Analysis Reveals Effects of Taxa and Age Despite Critical Research Gaps. [PDF]
Ecol EvolThis meta‐analysis on intraspecific variation in European trees studied the frequency of provenance variation, provenance–environment interaction, clinal variation along the climate of origin or transfer distance. While identifying trait group specific patterns of variation, research gaps have been identified in terms of age and geographical ...

Is the double-spined bark beetle Ips duplicatus a new threat to Picea omorika in urban habitats?
Plant Protection Science, 2021 The double-spined bark beetle Ips duplicatus (Coleoptera: Curculionidae, Scolytinae) is an invasive forest pest having a broad range of coniferous hosts within Europe. We found this species to be also developing in the Serbian spruce Picea omorika.
