Antioxidative enzymes during germination of two lines of Serbian spruce [Picea omorika (Panč.) Purkyně] [PDF]
Archives of Biological Sciences, 2007 Two lines of Picea omorika (Panč.) Purkyně were compared with respect to germination percentage as well as specific activity and isoenzyme pattern of catalase, superoxide dismutase, and peroxidase (POD) during germination. Line A had a higher 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 ...

ClAPRT3-Mediated Adenine Salvage Pathway Enhances Purine Metabolites to Sustain Seed Vigour During Selfing in Cunninghamia lanceolata. [PDF]
Plant Biotechnol JABSTRACT Selfing often causes inbreeding depression, especially during seed and seedling stages. However, some selfed progeny show low inbreeding depression with enhanced vigour, differing from inbred counterparts. This study investigates the molecular mechanisms maintaining seed vigour during selfing in Cunninghamia lanceolata.

First automatic size measurements for the separation of dwarf birch and tree birch pollen in MIS 6 to MIS 1 records from Northern Germany. [PDF]
Ecol EvolUsing image recognition with a series of convolutional networks and machine learning, we automatically measure the size of fossil birch pollen from sediment samples. The measurements are useful for determining the presence of dwarf birches versus tree birches in the past.

Cell wall response to UV radiation in needles of Picea omorika [PDF]
Plant Physiology and Biochemistry, 2021 The UV-B represents the minor fraction of the solar spectrum, while UV-C is not contained in natural solar radiation, but both radiation types can cause damaging effects in plants. Cell walls (CWs) are one of the targets for external stressors. Juvenile P.

Variability of in vitro germination of Picea omorika pollen [PDF]
Dendrobiology, 2012 Serbian spruce (Picea omorika /Panc./Purkyne) is a Balkan endemic and Tertiary relict, therefore it has an exceptional significance from the historical-geographical aspect as well as from the aspect of tree im- provement and biodiversity conservation. Pollen was collected from 24 trees in two consecutive years and an- alyzed once a month.
