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.).

Predicting postfire mortality of Pinus halepensis Mill. and Pinus pinea L.

Plant Ecology, 2004
The probability of mortality of Pinus halepensis and P. pinea trees after 6 separate wildfires (which took place from 1989 to 1991 in South Eastern France) was modelled with logistic regression analysis using data on tree size and fire-damage descriptors from 998 trees in 13 stands.

SALT STRESS RESPONSES IN PINUS HALEPENSIS

2011
Metapontum Forest Reserve is an artificial formation located between mouths of Bradano and Basento river, it is composed prevalently of Aleppo pine (Pinus halepensis). In recent years, the Metapontum coast is characterized by a strong erosive process which has really removed the dune behind the beach moving in the inland and causing the decline of the ...

Pinus halepensis mill. Architectural analysis for fuel modelling

2007
A fire behaviour model based on the complete physical and multiphase approach has been developed in order to study fuel treatment efficiency at the wildland urban interface. The fire behaviour model is currently running in 2 dimensions (x, z) and requires a complete description of the vegetation in a 25 cm x 25 cm grid.

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 ...
