ClAPRT3-Mediated Adenine Salvage Pathway Enhances Purine Metabolites to Sustain Seed Vigour During Selfing in Cunninghamia lanceolata. [PDF]

Plant Biotechnol J
ABSTRACT 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.

Some traces of interlinguistic contacts in the central Balkan mountains [PDF]

Balcanica, 2003
The etymology of three Balkan tree names, S.-Cr. munika ‘Pinus leucodermis' molika ‘Pinus peuce' and omorika ‘Picea omorika' is discussed. The latter is supposed to go back, together with Bulg.

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 Evol
Using 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.

Commodity risk assessment of debarked conifer wood chips fumigated with sulfuryl fluoride from the US. [PDF]

EFSA J
Abstract The European Commission requested the EFSA Panel on Plant Health to deliver a risk assessment on the likelihood of pest freedom from regulated EU quarantine pests, with emphasis on Bursaphelenchus xylophilus and its vectors Monochamus spp. of debarked conifer wood chips fumigated with sulfuryl fluoride as proposed by the United States (US) and

Antioxidant enzymes in the needles of different omorika lines [PDF]

Archives of Biological Sciences, 2005
Picea omorika (Panč) Purkyně (Serbian spruce) is a Balkan endemic coniferous species. We studied soluble peroxidase, catalase, polyphenol oxidase, and superoxide-dismutase activity in the needles of five omorika lines grown in a generative seed orchard ...

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

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.

Multiple forms of superoxide dismutase in the apoplast and whole-needle extract of Serbian spruce [Picea omorika (Panč.) Purkyně] [PDF]

Archives of Biological Sciences, 2006
Activity and isoenzyme composition of superoxide dismutase in the apoplast and whole-needle extract of Picea omorika (Panč.) Purkyně, was studied. Total SOD activity of the soluble fraction of the needle extract exceeded markedly that of the apoplastic ...

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
