Thesis (MScAgric)--Stellenbosch University, 2011.<br>ENGLISH ABSTRACT: Glyphosate remains an important herbicide in weed control. This is due to several positive attributes it has including sytemicity, wide spectrum of weed control and environmental friendliness. Its efficacy and lack of residual activity are therefore important to ensure adequate weed control without imposing hazards to the environment. Despite these favourable attributes for weed control glyphosate has its shortcomings. Evolution of resistance to glyphosate has been a major concern from 1996. However, there are other f

Abstract:

The dynamics of root carbon have been studied on a limited number of plants under a limited range of environmental conditions. This is particularly true of temperate pasture grasses. It was proposed to investigate rhizosphere carbon flow within Lolium perenne, to determine environmental factors affecting root exudation and root respiration. A number of microcosms were designed in which ryegrass could be pulse labelled with 14C-CO2, and the fate of the label determined within a plant-soil system. A wide range of factors were found to affect the distribution of carbon within the plant and soil u

The overall aim of this thesis was, to evaluate the potential of molecular markers, specifically SNPs and microsatellites, within DUS (Distinct, Uniform and Stable) testing of Lolium species.

As candidates pass, they become part of the reference collection. The reference collection is reaching an unmanageable size; therefore alternative testing methods are being sought.

Abstract:

Self-incompatibility (SI) prevents pollination by “self” pollen and promotes outbreeding. SI is a widespread mechanism among angiosperms. Grass SI is known to be controlled by two loci, S and Z, mapped in linkage group 1 and 2 respectively but the mechanism remains elusive. SI in perennial ryegrass (Lolium perenne L.) is studied at the gene level for the S-locus. Using a fine-mapping approach, followed by the sequencing of the genomic S-locus region and the transcripts from pollen and stigma, the project identified four stigma S-candidate genes and potentially six pollen S-candidate genes.

In addition a study of perennial ryegrass revealed that this resistance was independent of endophyte viability.

Perennial ryegrass (Lolium perenne L.) is one of the most economically and environmentally important grass species for the temperate zone. It maintains effective self-incompatibility (SI), which promotes outbreeding as well as limits the efficient production of inbred lines and hybrids. SI in L. perenne is controlled by the S and Z loci, mapping to linkage groups 1 and 2, respectively. None of the gene products has been identified so far. Comparative mapping has identified regions on rice chromosomes 5 (R5) and 4 with synteny to regions of L. perenne genome containing the S and Z loci, respect

Abstract:

O objetivo deste trabalho foi desenvolver e aplicar um modelo de Análise de Risco Ecológico (ARE) com vistas a classificar os riscos associados às emissões atmosféricas em áreas industriais a partir da utilização do bioindicador vegetal Lolium multiflorum e da aplicação dos princípios de análise de risco ecológico utilizado em ambientes aquáticos e solos contaminados. O trabalho foi desenvolvido no período de janeiro de 2005 a abril de 2008 no entorno da refinaria de petróleo, Alberto Pasqualini, através de duas estações amostrais situadas nos municípios de Canoas (29°55'07" S 51°10'54" O) e E

Abstract:

Production and consumption of ruminant products is partly being held accountable for the increasing global challenges of human health and climate change. Also, increasing demand for food, feed and fuel is placing growing pressure on land availability. One area under investigation in response to these challenges is fatty acid content of forages. This thesis sets out to investigate the variation and relationships between fatty acids, lipids, chlorophyll and other nutritional aspects of perennial ryegrass. Additionally, it will investigate alternative methods to predict fatty acids in forage. The
