Abstract:
Breast cancer is a leading cause of cancer related mortality globally, and epidemiological studies suggest a link between healthy nutrition and cancer prevention. Members of the Brassicaceae family, including watercress, have been extensively studied for their anti-cancer and anti-genotoxic potential. Watercress has a complex phytonutrient profile characterised by high levels of carotenoids, flavonols and glucosinolates. Extracts of watercress exhibit strong antioxidant capacity in vitro. Watercress and its components have been associated with the inhibition of the three stages of carcinogenes

Abstract:
Epidemiological studies indicate that there is an inverse relationship between consumption of cruciferous vegetables and risk of cancer. As a result there is much interest in understanding the anticancer potential not only of cruciferous vegetables themselves but also of the key phytochemicals contained in them. This project focuses on the potential anticancer properties of watercress, a cruciferous vegetable which is cultivated around the world and eaten raw as a salad vegetable as well as in cooked dishes. Watercress is the most abundant source of gluconasturtiin, a precursor to the phytoche

Abstract:
Despite the increased prominence of ecological measurement in fresh waters within recent national regulatory and legislative instruments, their assessment is still almost exclusively based on taxonomic structure. Integrated metrics of structure and function, though widely advocated, to date have not been incorporated into these bioassessment programmes. We sought to address this, by assessing community structure (macroinvertebrate assemblage composition) and ecosystem functioning (decomposition, primary production, and herbivory rates), in a series of replicated field experiments, at watercres

Abstract:
Scholarly works on agricultural and food history, on cultural geography and on landscape have long informed and enriched geographical thinking. However few researchers have drawn from these extensive bodies of work in order to investigate the cultural landscapes of food. This thesis aims to address that. It proposes the notion that foods can and do have cultural landscapes; landscapes that exhibit temporal changes which reflect changes occurring in the wider society. It goes on to investigate this notion through an historical case study of one particular food: watercress. Watercress itself has

The plasmodiophorid organism, Spongospora subterranea f. sp. nasturtii, is the causal agent of crook root disease of watercress (Rorippa nasturtium-aquaticumy. The only current control measure is zinc, used such that levels do not exceed 0.07S~g mrl in effluent water. Laboratory results indicated that zinc acts by actively lysing zoospores of S. subterranea, but does not cause 100% mortality at field concentrations. At 8ug ml", around 20 % of zoospores were seen to survive compared to controls. Of other cations investigated as potential control agents, none were as effective as zinc at equival

Watercress (<i>Nasturtium officinale</i> R. Br.; Brassicaceae) has a long history of human use for medicine and consumption. In recent years, it has received a large deal of attention as one of the most nutrient-dense foods. Despite this, watercress remains largely underdeveloped with limited breeding resources through which to meet current and future intensifying market demands, such as for a more compact morphology, enhanced nutritional benefits and resource-use efficiency.

Purple nutsedge (Cyperus rotundus) is a troublesome weed that outcompetes crops and contributes to poor yields.

This study evaluated the effectiveness of several alternative purple nutsedge control techniques and compared them with results obtained from the application of Roundup.
