“…The natural range of Cedrus atlantica Manetti is mainly limited to the Algerian and Moroccan mountains (Boudy 1950, Arbez et al 1978. In Morocco, the Atlas cedar covers an area of approximately 132000 hectares located mainly in the Middle Atlas.…”

The Atlas cedar, Cedrus atlantica is a resinous species of Pinaceae originated from North Africa and well known for its noble timber. This work was conducted to assess the natural durability of its wood, to study the chemical composition of essential oil extracted from its sawdust wood and to test the bioactivity of this essential oil against four wood decaying fungi: Gloeophyllum trabeum, Oligoporus placenta, Coniophora puteana and Trametes versicolor. The assessment of natural durability of wood was conducted according to the methods described in the European standards, CEN/TS 15083-1 and NF EN 350-1. Mass losses of wood specimens, after 16 weeks of exposure to fungi attack, in laboratory test, showed that Cedrus atlantica wood is very durable to durable against wood decay fungi attack. The extraction of essential oil from sawdust by hydro-distillation yielded about 3,35% and the chemical analysis of this essential oil by GC-MS showed that E-γ-Atlantone (19,73%); E-α-Atlantone (16,86%), 5-Isocedranol (11,68%); 9-iso-Thujopsanone (4,45%); Cedranone (4,13%) and Z α-Atlantone (4,02%) were the main major identified components. The antifungal activity tested by the direct contact technique on agar medium showed a strong inhibition of wood decaying fungi, especially Gloeophyllum trabeum inhibited at 1/1000 v/v concentration.

“…Studies carried out on the Cedrus genus have revealed some inter-and intra-species variability based on morphology (auxiblast and brachyblast length, number of needles per cluster, Arbez et al 1978) as well as physiology (changes in net photosynthesis as a function of water potential, Aussenac and Finkelstein 1983). In comparative plantations in Mediterranean France, growth differs significantly among cedar provenances from different geographic origins.…”

Three-and four-year-old potted, greenhousegrown cedar seedlings were subjected to two different watering regimes: half received full water supply and the other half was submitted to moderate drought (50% of the full water supply). Height growth was the greatest for C. atlantica and the most-limited for C. brevifolia in the well-watered set. However, in the dry set, height growth was less affected by drought conditions for C. brevifolia than for C. atlantica. Cedrus libani gave intermediate results for both watering regimes. Moderate drought provoked a decrease in osmotic potential at full leaf turgor and a long-lasting osmotic adjustment. When irrigation was withheld completely to induce severe soil drying, gas exchange decreased and then stopped at predawn water potentials of − 3.0 MPa for C. brevifolia, between − 2.6 and − 2.8 MPa for C. libani, and at − 2.4 MPa for C. atlantica, irrespective of watering regime. For all species, the dry set showed lower net photosynthesis (A) and stomatal conductance (g s ) than the plants in the wellwatered set. A and g s responded to variations in atmospheric water-vapour pressure deficit (VPD). As VPD increased, A and g s decreased, and this trend was proportionate to initial values at low VPD, but remained independent of previous watering treatments, plant water status or species. To conclude, C. brevifolia appears to be a species with limited growth potential but strong soil drought tolerance whereas C. atlantica has strong growth potential when an adequate water supply is available but is more sensitive to soil drought.

“…is a species with marked diversity. High variability in morphological and anatomical traits (Delevoy 1949;Wright and Bull 1962;Gellini 1968;Lee 1968;Arbez and Millier 1971) as well as the fact that geographic groups are regionally inter-fertile (Vidakovic 1991) burdened the systematics of this species in numerous classifications mostly based on the synthesis of phytocoenological, phytogeographical and morphological investigations. Corsica, Herault and the East Pyrenees are the western part of its broad and rather interrupted area (Regato-Pajares 1992).…”

The geographical variation of terpenes of Pinus nigra populations from southwestern Europe was studied. Terpenes from the foliage of 16 populations from Corsica, Herault (France) and the East Pyrenees (France and Spain) were analyzed. A total of 42 terpenes were detected, with α-pinene the dominant monoterpene and germacrene-d and caryophyllene the dominant sesquiterpenes. The differences in quantitative content of selected compounds clearly divide populations into two basic geographical groups: on one side the populations from Herault and the East Pyrenees and on the other the populations from Corsica. β-Phellandrene and δ-cadinene have the greatest influence on this global discrimination. Some trees and populations show a similarity although they belong to different geographic locations. The similarity of some trees S. Bojovic ( ) · P. Pavlovic · M. Mitrovic · L. Djurdjevic from Herault and the East Pyrenees and trees from Corsica points to their common origin (Corsica). Our results confirm the hypothesis that the afforestation of Herault and the East Pyrenees was also performed with black pine from Corsica.
