The objective of this work was to establish a cell suspension culture from Armeria maritima (Mill.) WilId., an halophyte so far only valuable for horticultural purposes, as a pre-requisite step towards the production of bioactives secondary metabolites in vitro. For the initiation of callogenesis, five types of explants were tested: leaves from mat...
L'étude phytochimique d'Armeria maritima et d'Helichrysum stoechas a permis d'isoler pour la première fois 31 molécules dans le genre Armeria dont 4 nouveaux flavonols diglycosylés, ainsi que le développement d'une stratégie de déréplication pour l'étude d'H. stoechas. Dans les deux espèces, nous avons relevé une richesse en polyphénols, qui pourra...

In the framework of an ecological risk assessment of seaport sediments for terrestrial ecosystems when deposited in quarries, we simulated the "ageing" of sediments exposed to rain. This experiment highlighted an inflection point at the solid/liquid ratio 1/25, after which the extraction of pollutants increases moderately. The raw sediments studied...

The filling of dry quarries in coastal areas with sediments dredged in seaports represents a potentially interesting method of recycling of these materials. However, this recycling requires the prior carrying out of an Environmental Risk Assessment of the scenario concerned. For this, the question arose as to the type of plants capable of developin...

Preliminary field studies were carried out at Dolfrwynog Bog in July 2000. Replicate samples of water, Armeria maritima plants and the soils adhering to its roots were collected and analysed for copper. Concentrations of up to 6486 mg kg−1 of copper in the soils were recorded. Accumulation of copper by the plant as expressed by concentration factor...
