The growth and water relations of a coastal halophyte, Salicornia bigelovii

Weeks, Jon Randall,1949- January 1986 (has links)
The succulent, annual euhalophyte, Salicornia bigelovii was grown in 1, 10, 35, 45 and 60 ppt Instant Ocean. This range represents approximately 1/35 to nearly twice the salinity of seawater. The plants in the 4 highest salinities had common final dry weights and seed yields of about 60 and 11 g, respectively, while the 1 ppt plants had 28 and nearly 5 g, respectively. The water relations data reflected the growth and seed production of the plants. The plants in the 4 higher salinities had water potentials sufficient to generate large import gradients and osmotic potentials which contributed to substantial turgors. The 1 ppt plants had a gradient like the rest, but a very low turgor of 0.11 MPa which was barely 23% of that of the lowest of the other treatments. Higher salinities resulted in slightly greater organic and inorganic osmotica contents. Overall, these results suggest a relatively fixed genetic response to a wide range of salinities, as well as an inability to function well at very low salinities. No plant grown at 0 ppt was ever able to reproduce. Therefore, this plant is an obligate halophyte. Experiments in the plant's native coastal estuary indicated meristem water potentials fluctuate with the tides, although they remain about 1.5 MPa below the corresponding soil water potentials. The plants occupy a discrete elevational range throughout the estuary, spending about 1/3 of their daylight hours submerged, and apparently never see dryness. Phenotype differences in the estuary suggest that, within the habitat, pacing and consequent resource domination may be important parameters affecting plant size and possibly fitness. Nitrogen, which is characteristically rare in this and other estuaries, may be critical in this regard. The plants produce large quantities of glycine-betaine, which may be for simultaneous osmoticum use and nitrogen storage. Most roots occur in the first 3 inches of soil. A mechanism is proposed, based on highly efficient compartmentation at the cellular level and the shuttling of organic osmoticum across the tonoplast, by which the tidally based cyclical water potentials could be explained.

Étude de l'agroraffinage de graines d'Apiaceae, Lamiaceae et Chenopodiaceae pour la production de molécules biosourcées en vue d'application en industrie cosmétique

Sayed Ahmad, Bouchra 15 January 2018 (has links) (PDF)
La croissance démographique, la consommation incontrôlée des ressources naturelles ainsi que l’activité industrielle jouent un rôle déterminant dans la dégradation de l'environnement mondial. A ce sujet et en se basant sur le concept que les consommateurs partagent la responsabilité de la pollution et de l'épuisement des ressources et leur coût, la mise en oeuvre des ressources renouvelables dans les processus industriels apparait comme une clé décisive. La renouvelabilité, la recyclabilité, la durabilité, la biodégradabilité sont les concepts de base sur lesquels nous pouvons compter pour protéger la nature et l’environnement. Dans ce contexte, une nouvelle approche de la bioraffinage a été développée dans cette thèse, elle a été appliquée à cinq espèces appartenant à 3 familles différentes (Foeniculum vulagre, Cuminum cyminum and Carum carvi (Apiaceae), Salvia hispania (Lamiaceae) et Amaranthus cruentus (Amaranthaceae)). Ces espèces partagent une caractéristique commune, elles peuvent être définies comme Aroma Tincto Oleo Crops (ATOC) puisqu’elles sont une source d'huile végétale et d'huile essentielle (ou de colorant). Notre objectif est donc de déterminer la faisabilité biologique et technologique de l'application du concept ATOC-bioraffinage basé sur le développement, l'optimisation et la production de nouveaux produits biologiques, des nouvelles molécules biosourcées et d'autres technologies innovantes. Notre étude met l'accent sur l'évaluation de divers paramètres influençant le rendement et la qualité de l’huile dans les graines d'ATOC, y compris leurs origines géographiques et le procédé d'extraction, et leur impact sur l'activité biologique des extraits de résidus. La valorisation des huiles pour des applications dans l’industrie cosmétique a été realisée en les utilisant comme (i) additifs dans des formulations de crème hydratante. De plus, l’utilité du tourteau d'extraction comme (ii) substrat pour la fabrication d'agromatériaux par thermopressage et comme (iii) un ingrédient dans des formulations de pain de blé entier a été examinée.
