Seed germination of Pinus halepensis provenances under NaCl stress

Israel Journal of Plant Sciences, 2004
Pinus halepensis seeds from nine European provenances were germinated in NaCl solutions. Inhibition of germination was not due solely to osmotic effects, but also to ion toxicity, as observed by comparing germination in NaCl to germination in isotonic solutions of polyethylene glycol. The negative ion effect did not vary among provenances.

Resin is a secondary forestry product of significant economic value. Its individual components are used in several different sectors of craft and industry. Resin is produced from different species of conifer trees. In Greece, the resin producing species are Aleppo pine, Brutia and Black pine, with Aleppo pine being the most productive species.

‘Candidatus Phytoplasma pini’, a novel taxon from Pinus silvestris and Pinus halepensis

International Journal of Systematic and Evolutionary Microbiology, 2005
Pinus silvestris and Pinus halepensis trees grown in Germany and Spain, respectively, showing abnormal shoot branching, dwarfed needles and other symptoms were examined for the presence of plant-pathogenic mollicutes (phytoplasmas). While phytoplasmas could not be detected unambiguously with microscopical methods, PCR amplification ...

Chemical characterization ofPinus halepensissapwood and heartwood

Wood Material Science & Engineering, 2018
ABSTRACTThis paper describes the chemical composition of sapwood (SW) and heartwood (HW) of Pinus halepensis Mill stem. Extractives were first isolated by accelerated solvent extraction and then analysed by gas chromatography-mass spectrometry (GC-MS).

Genetic differences between Pinus halepensis, Pinus brutia and Pinus eldarica based on needle flavonoids

Biochemical Systematics and Ecology, 1997
A chemosystematic study based on needle flavonoids, was carried out on 324 trees from six populations of Pinus halepensis, six of Pinus brutia and one of Pinus eldarica. Two main flavonoid classes were identified and measured by HPLC: (pro)anthocyanins and flavonols.

Morphological and Physiological Damage by Surfactant-Polluted Seaspray on Pinus pinea and Pinus halepensis

Environmental Monitoring and Assessment, 2005
This paper reports morphological and physiological damage caused by polluted seaspray to coastal pine forests in Liguria (Northern Italy) and suggests the most reliable parameters for surfactant-pollution biomonitoring. Concentrations of surfactants in surface seawater, seaspray, and that deposited on Pinus halepensis and Pinus pinea needles were ...

Structure and ultrastructure of Pinus halepensis primary needles

Flora - Morphology, Distribution, Functional Ecology of Plants, 2002
Summary This study using light, transmission and scanning electron microscopy, describes the structure of Pinus halepensis primary needles collected from seedlings 22 and 24 weeks after emergence. P. halepensis is a circum-mediterranean pine of high importance for ecosystem maintenance and reforestation, in which primary needles are formed three ...

Allelopathic potential of Pinus halepensis needles

2016
The green and mature senescent needles of Pinus halepensis from the Tunisian pine forests of Bizerte, Tabarka, Seliana and Oueslatia were evaluated based on their phytochemicals contents for allelopathic potential on seed germination and seedling growth of radish (Raphanus sativus L.) and wheat (Triticum aestivum L.).
