Streszczenie:

"Artemisinin is a potent antimalarial drug produced in the plant Artemisia annua. Earlier reports suggested that the roots play a key role in artemisinin production; however, it was not clear if other factors actually affected production instead of roots. Here the role of roots and two phytohormones, NAA and BAP, were studied to determine what role each plays in artemisinin production in the plant. Rooted Artemisia annua shoots produced significantly more artemisinin, arteannuin B, and deoxyartemisinin, the end products in the pathway, than unrooted shoots. Although roots do not seem to affect

Streszczenie:

Artemisinin is a potent antimalarial sesquiterpene lactone produced and stored in the glandular trichomes (GLTs) of Artemisia annua. Although they produce no artemisinin, nor any of the precursor compounds, A. annua roots appear to have a regulatory effect on production of the terpene in leaves. However, more information is needed to define the role of the roots in artemisinin production in the plant. Grafting among three cultivars was used to measure phenotypic responses: SAM, and #15 cultivars both have GLTs, but produce artemisinin at 1.49% and 0.57% DW, respectively; GLS cultivar produces

Historical origins in mission endeavour shed light on the indigenous development of these Charismatic Brethren and Pentecostal Evangelicals. This new expression of faith is shown to be well ad

Toxic elements are present in polluted water from mines, industrial outlets, storm water etc. Wetland plants take up toxic elements and increase the pH of the medium.

The aim was to clarify the mechanisms by which these plants change the surrounding water pH in the presence of toxic ions.

Wheat (Triticum aestivum L.) is one of the most important cereal crops in the world. In order to meet the food requirements of the current trend in population growth, enhancement in wheat production and yield are urgently needed. Water and temperature stress are major constraints to wheat production and subsequently food security in the context of climate change. Plant growth is affected by both above- and belowground environmental conditions and increasing atmospheric CO2 concentrations have been reported to enhance growth and yield of most agricultural crops.

Three single-extraction procedures are evaluated for their usefulness for identifying the bioavailable fractions of trace metals in soil. Plant-available Zn, Cd, Pb, Ni, and Cu were estimated using elemental analysis, pH, organic matter, and soil texture. Specific geochemical factors such as oxidizing conditions and the presence of Fe-, Al-, and Mn-oxides suggest trace metal mobility in

In nutrient broth, as the growth rate declined, HHL synthesis increased rapidly. Up to 38% more HHL was produced compared to the increase in cell numbers indicating that transcription of the phenazine operon was auto induced.

Partial rootzone drying (PRD) is an irrigation management technique designed to reduce water use in grapevines without a decline in yield, thereby increasing water–use efficiency (measured as t/ML) (WUE). The principle of PRD is to keep part of the root system at a constant drying rate to produce soil-derived signals to above–ground plant organs to induce a physiological response. Major PRD effects include a reduced canopy size and greatly increased WUE with possible improvements in fruit quality. Although we have a good understanding of the hormonal physiology of PRD, little is known on the e

The climatic effects imprint dynamics specific to pasture ecosystems, which are generally referred as "seasonality of the pasture."

Streszczenie:

Fine roots constitute a large part of the primary production in northern (arctic and boreal) ecosystems, and are key players in ecosystem fluxes of water, nutrients and carbon. Data on root dynamics are generally rare, especially so in northern ecosystems. However, those ecosystems undergo the most rapid climatic changes on the planet and a profound understanding of form, function and dynamics of roots in such ecosystems is essential. This thesis aimed to advance our knowledge about fine root dynamics in northern ecosystems, with a focus on fine root phenology in natural plant communities and

As disponibilidades de fósforo e zinco afetam as características estruturais, fisiológicas, metabólicas e produtivas das plantas, com reflexos no estabelecimento e produção de forragem da gramínea forrageira. Objetivou-se identificar e quantificar as alterações nas concentrações foliares de fósforo e zinco, trocas gasosas, concentração do aminoácido triptofano, atividade da enzima fosfatase ácida, área foliar, números de folhas e de perfilhos, sistema radicular e massa de forragem da Brachiaria brizantha cv.

Le phytomanagement compte parmi les méthodes innovantes de gestion des sites et sols pollués en raison de son adéquation avec le développement durable. Pour répondre à la double exigence de performances environnementales et économiques, les phytotechnologies sont désormais combinées à la valorisation de la biomasse produite sur sols pollués. Parmi les filières éco-innovantes et non-alimentaires de valorisation de cette biomasse, la culture de plantes à parfums, aromatiques et médicinales (PPAM) pour la production d’huiles essentielles (HE), substances biosourcées à haute valeur ajoutée, a été

Originating from a disenfranchisement with the contemporary definition and realisation of Westernised architecture as a commodity and product, this thesis seeks to explore alternative examples of positive socio-spatial practice and agency. These alternative spatial practices and methodologies are drawn from participatory and grass-roots development agency in informal settlements and contexts of economic absence, most notably in the global South. This thesis explores whether such examples can be interpreted as practical realisations of key theoretical advocacies for positive social space that h

This item is only available electronically.<br>Short-term thinking is a dominant Western worldview and is reflected in many educational practices, many of which concentrate on the assessment of certain kinds of knowledges. Despite the assumption that education prepares students for their future, it often lacks a long-term vision of what that future may be. Furthermore, conventional education has overlooked fundamental questions of sustainability facing future generations. The future cannot be predicted with certainty; however, it can be said that the current and looming ecological crises will

博士<br>國立臺灣大學<br>農藝學研究所<br>103<br>Abstract Climate changes and environmental stresses become severe over the past few decades. In particular, different abiotic stresses reduce the yield and quality of crop, leading to the threaten of global food security. With the deciphering of rice genome and advancement of functional genomics technology, researchers were able to gradually reveal the mechanism of abiotic stress tolerance mechanisms in rice and to identify essential genes for breeding to improve stress tolerance. In this thesis, we used TNG67 (japonica) and TCN1 (indica) rice cultivars with c

In South Africa, clonal forestry of Eucalyptus and its hybrids has been implemented to increase the productivity on existing forestry lands and marginal sites and to facilitate the production of desired fibre types for timber processing operations. The cold-tolerant Eucalyptus grandis x E. nitens hybrids have produced consistently high yields, and are propagated clonally with limited success via a macro-cutting system currently in use for other hybrid species. The heart of vegetative propagation operations is the clonal hedge and its management, and nutrition in particular, is an important ele
