Water Conservation Through Drought-Resilient Landscape Plants And Deficit Irrigation, Ji-Jhong Chen
All Graduate Theses and Dissertations
Increases in urban population and inadequate rainfall result in imbalanced water budgets in urban and sub-urban regions. Water conservation becomes important in urban landscapes because of increased water demands. Modern landscape designs require drought-resistant plants to maintain urban landscape greenness during water scarcity. Irrigating plants at their irrigation requirements, which is the minimum irrigation rate that can achieve acceptable aesthetic quality, can also conserve water. However, the drought tolerance and irrigation requrements of most landscape plants have not been widely evaluated. Shepherdia ×utahensis ‘Torrey’ (‘Torrey’ buffaloberry) and Penstemon species (beardtongues) are low-water-use landscape plants, but their drought resistance mechanisms are …

Reintroducing Hemp (Rongony) In The Material Palette Of Madagascar: A Study On The Potential Of Hemp Clay Components And Its Impact On Social And Ecological Communities., Henintsoa Thierry Andrianambinina
Masters Theses
When mentioning the word hemp, especially in the local language of Madagascar, the literal translation does not set it apart from marijuana, as they are both called “rongony” - creating the stigma around hemp as the negative stereotype of marijuana. However, the material has been used by the ancestors of Madagascar, as well as across cultures, in its fibrous form to produce fabrication like textile goods and packaging. During colonization, the prohibition of hemp intensified, and since then, any activity related to either of these plants is prohibited and will end in severe punitive measures. This thesis explores the strengths …

Characterization Of Boreal-Arctic Vegetation Growth Phases And Active Soil Layer Dynamics In The High-Latitudes Of North America: A Study Combining Multi-Year In Situ And Satellite-Based Observations, Michael G. Brown
Dissertations, Theses, and Capstone Projects
This dissertation examined the seasonal freeze/thaw activity in boreal-Arctic soils and vegetation physiology in Alaska, USA and Alberta, Canada, using in situ environmental measurements and passive microwave satellite observations. The boreal-Arctic high-latitudes have been experiencing ecosystem changes more rapidly in comparison to the rest of Earth due to the presently warming climatic conditions having a magnified effect over Polar Regions. Currently, the boreal-Arctic is a carbon sink; however, recent studies indicate a shift over the next century to become a carbon source. High-latitude vegetation and cold soil dynamics are influenced by climatic shifts and are largely responsible for the regions …

Effect Of Condensed Tannins In Sainfoin On In Vitro Protein Solubility Of Lucerne, J. Aufrère, M. Dudilieu, C. Poncet, R. Baumont
International Grassland Congress Proceedings
Proteins of fresh legume forages such as lucerne are highly degraded in the rumen, resulting in their inefficient use by the animal. The condensed tannins (CT) present in some forages can improve the nutritional value of these forages and of associated feeds in the diet. Previous in vitro work (Waghorn & Shelton, 1997) showed that CT from Lotus corniculatus are able to bind with and precipitate protein from a ryegrass/clover pasture, but when these forages were fed to sheep, the CT effects on digestion and animal performance were weak. This revealed a need for a better understanding of the mechanism …

Lotus glaber (Lg) grows on clay, sandy and medium textured soils in central Chile (32º to 38º S). The diversity of environments where the species grows naturally supports the hypothesis that genetic variability would be found. The objectives of the experiment were to characterise accessions of Lg collected in the region for dry matter (DM) production, comparative capacity to fix atmospheric N and condensed tannins (CT) in Lg grown on clay soils used for cropping rice.

Condensed Tannins In Different Varieties Of Lotus Corniculatus, Christina L. Marley, Rhun Fychan, R. Jones
International Grassland Congress Proceedings
Research has shown that Lotus corniculatus may provide benefits as a grazing forage for ruminants, because of improved efficiency of protein utilisation in part due to the presence of condensed tannins (CT) in the forage. Lotus species have been found to contain different CT (Aerts et al., 1999). The aim of this experiment was to determine if differences exist in CT concentration among L. corniculatus varieties.

Ariation In Tannin Content And Morphological Traits In Lotus Corniculatus L. (Bird’S-Foot Trefoil), A. H. Marshall, F. Ribaimont, R. P. Collins, D. Bryant, M. T. Abberton
International Grassland Congress Proceedings
Lotus corniculatus L. (bird's-foot trefoil) is a potentially valuable species for UK grassland agriculture. The herbage contains proanthocyanidins, or condensed tannins (CT's), which help to reduce bloat, have anthelmintic properties, can protect protein in the rumen, and thus potentially reduce N losses to the environment. It is currently a relatively minor species within UK grassland, as available varieties lack persistence in mixed swards (Hopkins et al., 1996). The seed used is of foreign bred varieties with no varieties bred specifically for the UK environment. To explore the feasibility of breeding L. corniculatus for the UK, variation in morphological traits, …

Light Intensity Is Positively Correlated With The Synthesis Of Condensed Tannins In Lotus Corniculatus, Sergio Arcioni, T. Bovone, F. Damiani, F. Paolocci
International Grassland Congress Proceedings
The importance of Condensed Tannins (CT) in forage legumes has been well documented in several studies. The role of plant genetics in this field is the acquisition of competences in order to be able to modulate CT synthesis in leaves of these species. The role of light has been investigated in this work on the increase of condensed tannin levels in leaves of two contrasting genotypes of birdsfoot trefoil (Lotus corniculatus).

Condensed Tannin Concentration And Herbage Accumulation Of A White Clover Bred For Increased Floral Condensed Tannin, V. T. Burggraaf, S. L. Woodward, D. R. Woodfield, E. R. Thom, G. C. Waghorn, P. D. Kemp
International Grassland Congress Proceedings
White clover is a high quality feed for ruminants, however, its high protein content results in excessive urea excretion in urine and can cause bloat, reducing its potential value for animal production. The condensed tannins (CT) in some forages can reduce these problems, but plants may have poor agronomic performance. White clover produces CT in its flower heads, but herbage CT concentrations are normally too low to benefit animals. This paper reports CT concentrations and herbage accumulation over 2 years of an experimental line of white clover (HT) selected for increased flowering and floral CT concentrations.

Effects Of Simulated High-Sugar Forages On Grazing Behaviour Of Sheep, Gerald P. Cosgrove, A. J. Parsons
International Grassland Congress Proceedings
Sustaining an optimum composition in mixed-species pasture and in the diet of grazing animals is constrained by many factors. Altering the concentration of water soluble carbohydrate (WSC) of one species to improve its nutritional value for animals may not deliver the benefits in the assumed manner if it also affects preference and the balance of species in the pasture. Furthermore, associated changes in other constituents (e.g. fibre, protein) make it difficult to attribute animal responses solely to the manipulated trait (e.g. Lee et al. 2000). The objective of this study was to simulate changes in the concentration of water soluble …

High Floral Tannin White Clover Reduces Rumen Ammonia Concentrations In Dairy Cows, V. T. Burggraaf, G. C. Waghorn, S. L. Woodward, D. R. Woodfield, E. R. Thom, P. D. Kemp
International Grassland Congress Proceedings
White clover produces high quality forage for ruminant production, but it results in high rumen ammonia concentrations, indicating extensive protein degradation. The excess ammonia is absorbed through the rumen and excreted as urea in urine, at a cost to the animal and the environment. Condensed tannins (CT) contained in some forages reduce proteolysis in the rumen, which can lead to increased amino acid absorption and therefore improved animal performance. White clover produces CT in its flower heads, but concentrations are normally too low to benefit animals. This paper reports on comparisons of rumen ammonia concentrations in dairy cows grazing HT …

Substrate-Dependent Activation Of Polyphenol Oxidase In Red Clover, Ana L. Winters, F. R. Minchin, P. Morris
International Grassland Congress Proceedings
Polyphenol oxidases (PPO) are copper metaloproteins that catalyse the oxidation of o-diphenols to quinones, highly reactive molecules which readily bind to nucleophilic sites on cellular components and proteins. Red clover protein, due to this enzyme is resistant to protease degradation during. Theses enzymes (circa. 60-65 kDa) are located in the thylakoid lumen and can be converted to a 40-45 kDa form by proteolysis both in vitro and in vivo (Gelder et al., 1997). Conversion to the smaller form has been demonstrated to confer activity at neutral pH. Other treatments, such as the presence of lipids or detergents …

Variation In Protein Quality Of Forage Legumes During Spring Growth, M. Gierus, J. Kleen, F. Taube
International Grassland Congress Proceedings
The utilisation of forage legumes in combination with reduced N inputs as fertilisers is an alternative for the production of high quality forage. Although white clover (WC) is widely used in grassland and has a high content of crude protein (CP), a combination of this high CP content with a high proportion of rapidly-available proteins and fast degradation rate in the rumen may reduce the efficiency of N use by ruminants in comparison with other forage legumes. The objective of the present study was to investigate the variation in content of CP fractions A, B and C in different forage …

Effects Of Particle Size In Forage Samples For Protein Breakdown Studies, G. Pichard, C. Tapia
International Grassland Congress Proceedings
Coupling ruminal processes of hydrolysis and synthesis continues to be a research issue where more progress is needed. This requires the development of good protein assessment methods, particularly when representing the breakdown processes that occur in fresh pastures eaten by herbivores. Laboratory analyses need to deal with small and homogeneous samples, but the mechanical reduction of particle size may not reflect the actual digestion kinetics occurring when the original fresh forage is consumed. Such physical traits may alter the release of non-structural compounds and the penetration of microbial enzymes (Boudon et al., 2002). The objective of this work was …

Ruminal Dry Matter, Neutral Detergent Fibre And Acid Detergent Fiber Degradation Kinetics Of Dominant Pasture Forages In Kurdestan Province Of Iran, A. A. Sadeghi, P. Shawrang, A. Nikkhah
International Grassland Congress Proceedings
Neutral detergent fiber (NDF) is a major chemical component of forages and its degradability (dNDF) is an essential parameter in predicting their energetic value. Moreover, dNDF has been used in models to estimate the physical fill of fibrous feeds in the rumen and, therefore, the intake capacity of animals. As the available information on the nutritive value of pastoral forages is limited a study was undertaken to measure chemical composition and cell wall degradation kinetics of eight pasture forages in the rumen.

International Grassland Congress Proceedings
Ammoniation has a high potential to increase the nutritive value (NV) of mature tropical grasses hays. Urea utilisation, like ammonia, seems to be a promising alternative for on-farm treatment of low quality forage in Brazil. Urea has the advantages over anhydrous ammonia of being widely available, easier to handle and, in some countries, less expensive. The aim of this work was to study the effects on the efficiency of urea treatment of palisade grass (Brachiaria brizantha cv. Marandu) hay of the moisture level, and the urease source.
