Abstract:

Pinus brutia var. eldarica is often considered to possess photosynthetic characteristics that make it highly tolerant to drought conditions. However, very little is known about it's photosynthetic response to water stress under either laboratory or field imposed drought conditions. The purpose of this study was to utilize laboratory gas-exchange measurements to determine the effects of water stress and recovery from stress on photosynthetic capacity of potted Pinus brutia via. eldarica plants. Analysis of the rate assimilation (A) versus intercellular CO₂ (Cᵢ) data indicates that recovery of c

Abstract:

The working hypothesis for this dissertation was that the contrasting plant architecture, and the distinct native environments of Hesperaloe funifera and H. nocturna should be reflected in differences in their eco-physiological responses, and that these, in turn, would determine these species' adaptability limits and productivity under cultivation. The objective of this dissertation project was to evaluate plant morphological characteristics and their effect on physiological processes, and how environmental factors interact with these processes in H. funifera and H. nocturna.

Abstract:

Water availability is one of the biggest constraints limiting the plant growth and species distribution around the world. This is the case in the Mediterranean region where, moreover, the frequency and amount of rainfall will decrease due to global warming. This will provoke longer periods of drought and a general decrease of water availability. In this context, one of the most vulnerable crops is grapevine. This crop has been traditionally rain-feed, although in recent years it’s becoming an irrigated crop. This increases the demand to regulate the water use by more precise irrigation

Worldwide, agriculture production continues to be constrained by a number of abiotic and biotic stresses. In areas with Mediterranean climate, drought events are expected to strengthen in terms of intensity, frequency and duration in the near future. Thus, in this area, soil water deficit is considered the main environmental factor influencing grapevine growth. At the same time, grapevines are highly subjected to different viruses from which Grapevine leafroll associated virus-3 (GLRaV-3) is one of the most widespread ones, provoking considerable economic losses in many vineyards worldwide.

O Brasil produz cerca de 340 mil toneladas de óleo-de-palma. A maior parte provém do território paraense que representa cerca de 90% da produção nacional de óleo-de-palma, com 160 mil hectares plantados em função da aptidão edafoclimática da região que possui condições favoráveis para o desenvolvimento da cultura. Diante da relevância desta cultura, os estudos aqui realizados foram conduzidos com o objetivo de fornecer informações sobre os aspectos fisiológicos, quantificação de biomassa, estoque de carbono e balanço nutricional em plantios de palma-de-óleo com 3, 4, 5, 6 e 7 anos de idade.

Abstract:

The saltbush is an C4 species extremely tolerant to soils and saline waters and has good capacity to accumulate quantities of salts in their tissues, also serving as forage potential. Therefore, it is an excellent material for the identification of physiological and biochemical mechanisms involved in the resistance to salinity. The objective of this study was to evaluate the ecophysiological and biochemical responses of saltbush under increasing levels of NaCl. Plants were grown in pots kept in a greenhouse and irrigated every 2 days at concentrations of 0, 150, 300, 450 and 600 mM NaCl over t

Abstract:

L'arsenic et l'antimoine bien que n'étant pas recensés parmi les polluants majeurs de l'environnement sont souvent retrouvés associés à d'autres contaminants. En France, et plus particulièrement dans la région Auvergne, de nombreux sites miniers où s'effectuait l'extraction de l'antimoine sont désormais à l'abandon. Pouvant présenter des risques pour les populations avoisinantes, leur réhabilitation est donc une mission d'intérêt public. L'idée de ce travail de doctorat est de tester l'effet d'un catalyseur : le ver de terre sur l'efficacité des processus de phytoremédiation. En tant qu'" ingé

Les challenges posés par les missions d’exploration du système solaire sont très différents de ceux de la Station Spatiale Internationale, puisque les distances sont beaucoup plus importantes, limitant la possibilité de ravitaillements réguliers. Les systèmes support-vie basés sur des plantes supérieures et des micro-organismes, comme le projet de l’Agence Spatiale Européenne (ESA) MELiSSA (Micro Ecological Life Support System Alternative) permettront aux équipages d’être autonomes en termes de production de nourriture, revitalisation de l’air et de recyclage d’eau, tout en fermant les cycles
