Procyanidine in Zapfen Von Pinus Halepensis

International Journal of Pharmacognosy, 1991
AbstractFrom The Unripe Cones Of Pinus Halepensis (Pinaceae), (+)- Catechin, (-)- Epicatechin and (+)-Gallocatechin As Peracetate Derivatives and Procyanidin Bl, B3, B4, B6 and B7 As Decaacetates Were Isolated and Identified. The Major Components Were (+)- Catechin, Procyanidin B3 and Procyanidin B6. The Unripe Cones Contained 4.63% Total Procyanidins.

Natural recolonization of Pinus halepensis Mill, and Pinus pinaster Aitón in burnt forests of the Sierra de Al caraz-Segura mountain system (SE Spain)

Ecologia Mediterranea, 1996
The natural recolonization by Pinus halepensis Miller and Pinus pinaster Aiton after several fires between 1975 and 1985 has been studied, recording the density and cover of pines in relation to the cover of other species occurring in permanent plots.

Population Genetics and Genomics of Aleppo Pine (Pinus halepensis)

2021
Aleppo pine (Pinus halepensis Mill.) has been studied with genetic markers over the last 20 years, in order to decipher its evolutionary history at both full-distribution and local scales, incorporating new insights as molecular technologies evolve. In this process, knowledge has accumulated on population diversity and structure, demographic history ...

Aleppo pine Pinus halepensis Mill.

2018
Aleppo pine (Pinus halepensis Mill.) is a medium size tree (20–40 m) that can display a shrubby phenotype when growing on harsh conditions (Eckenwalder, 2009).

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).

Impacts of urban levels of ozone on Pinus halepensis foliage

Environmental and Experimental Botany, 2000
Between May and September, 1996, seedlings of Pinus halepensis were placed at a site adjacent to an automated air pollution monitoring station within the urban area of Florence. Additional 'control' plants were placed in chambers ventilated with charcoal/Purafil(R)-filtered air.

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 ...

Effects of chronic gamma-irradiation on Pinus pinea and Pinus halepensis

Radiation Botany, 1967
Abstract A histological analysis has been made on shoot apices of Pinus pinea and Pinus halepensis collected from plants chronically irradiated in the gamma field (60Co source) at exposure rates of 18·8, 9·0, 4·30 and 2·64 R/day up to 1513 days, from plants exposed to 36·2, 20·6, 5·02 and 2·10 R/day and allowed to recover after receiving 1000 and ...

Isozyme variation and heterozygosity in Pinus halepensis L.

Biochemical Genetics, 1983
The genetic polymorphism of a population of Pinus halepensis was studied using 12 electrophoretically detectable enzyme systems encoded by 7 monomorphic and 10 polymorphic loci. An estimation of population parameters revealed a relatively high average heterozygosity (H = 0.179).

Effect of high temperatures on seed germination of Pinus sylvestris and Pinus halepensis

Forest Ecology and Management, 2000
Abstract Fire is one of the most important ecological factors in the Mediterranean forest ecosystems. Most Mediterranean conifers are obligate seeders after fire. Seeds of two conifers species (Pinus sylvestris and Pinus halepensis) were heated to a range of temperatures similar to those registered on surface soil during natural fires (from 70° to ...
