The objective of our study is to improve the growing medium, which has a direct effect on the quality of forest plants. The compost-based substrate in organic matter can be an alternative to potting soil. Two series of composts were studied, the first series with goat manure at 5%, and the second without manure. Each series consists of four types of composted forest residual materials : cedar cone residue ; leaves and twigs of Acacia mollissima ; leaves and twigs of holm oak and needles and twigs of Aleppo pine. They were tested on two forest species the cedar Cedrus atlantica and the oak Quercus ilex subsp. ballota. The physico-chemical analyzes of the various substrates clearly show differences in organic matter and mineral salts compared to the potting soil. The best substitutes for forest soil are compost substrates made from Acacia mollissima ; oak and Alep pine.

Four typ es of forest materials were composted (cones of Cedrus atlantica and green biomass residu es: leaves and branches of Quercus rotundifolia and Acacia mollissima as well as needled branches of Pinus halepensis). Net differen ces in the physico-chemical properties and temperat ure profiles were observed among the four types of compost. These differences are cl osely related to the nature of the material used fo r composting, the C/N ratio, the moisture content and the oxygen demand of the compost. Composting time was significantly reduced in comparison to previous studies. The physico-chemical properties of the compost are significantly better than to the forest soil. Withi n the context of the preliminary test, the results are strongly encouraging with respect t o the use of different composts to produce oak seed lings of high morpho-physiological quality.

Les résultats de l’étude de la toxicité font ressortir que la dose létale 50 des deux espèces est supérieure à 5 g/kg, ce qui implique que les deux plantes peuvent être classées dans la catégorie 5 selon le guideline de l’OCDE 423. En conséquence, Laurus nobilis et Vitex agnus-castus peuvent être considérées non toxiques. Les résultats des tests de Rota-Rod, de la planche à trous et de la chambre blanche/obscure ont démontré que les huiles essentielles de Laurus nobilis et de Vitex agnus-castus exercent un effet sédatif considérable chez la souris. Ces résultats suggèrent que Laurus nobilis et Vitex agnus-castus pourraient constituer une bonne alternative aux sédatifs de synthèse utilisés en industrie pharmaceutique.

Les huiles essentielles, obtenues par hydrodistillation des feuilles et jeunes rameaux du romarin, ont été analysées par CG/FID et CG/SM. Les huiles essentielles de ces trois provenances de romarin étudiées sont caractérisées par la présence des composés α et β- pinènes, camphène, 1,8-cinéole et camphre. La qualité des huiles essentielles étudiées respectent la Norme AFNOR NF ISO 4730 du romarin type Maroc (1,8-cinéole). L’évaluation de l’activité antimicrobienne des huiles essentielles du Rosmarinus officinalis des trois provenances a montré une faible efficacité contre les microorganismes testés qui ont été tous inhibés à partir de 1/100 v/v sauf pour Penicillium expansum dont la croissance a été arrêtée à la concentration 1/250 v/v.AbstractThis study is an assessment of the chemical quality and evaluation of antibacterial and antifungal activity of rosemary’s essential oils from three regions of Morocco (Rchida and Berkine/Eastern Morocco and Aknoul/North East of Morocco. The essential oils obtained by hydrodistillation of the leaves and young twigs of rosemary, were analyzed by GC / FID and GC/ MS. These essential oils are characterized by the presence of α and β-pinene, camphene, 1,8-cineole and camphor compounds. The quality of these essential oils met the AFNOR NF ISO 4730 rosemary Morocco kind (1,8-cineole). The evaluation of the antimicrobial activity of essential oils of Rosmarinus officinalis showed low efficacy against microorganisms tested which were all inhibited from 1/100 v/v except for Penicillium expansum whose growth was stopped at the concentration 1/250 v/v

The essential oils obtained from uncontaminated sawdust and contaminated by Trametes pini have sensibly identical chemical composition with himachalenes (α-, γ- and β-) and E-α-atlantone as major components, but this oils don't have antibacterial and antifungal activities. Those obtained from wood attacked by Ungulina officinalis, which have a different chemical composition, have a bacterial activity for a concentration of 2 μl/ml and a less antifungal activity.
