Marcele Vermeulen, a graduate from the Department of Plant Sciences, explores possible threats to crop production; contributing to food security in South Africa.
Global food security is currently threatened both by climate change and the low diversity of crops relied on by humankind to feed a growing world population. Marcele Vermeulen, a graduate in the Department of Plant Sciences who will receive her PhD at the December graduation ceremonies at the University of the Free State (UFS), is part of a team that is working hard to add to the diversity of staple foods in South Africa.

In the drive to focus on alternative crops, Marcele is researching the crop, Amaranthus cruentus, (grain amaranth). It is more tolerant to environmental stress for large-scale production, thereby also diversifying staple crops.

Relatively new development

“Amaranthus cruentus is an excellent candidate due to its high nutritional value and tolerance to drought and high temperatures. It can be mixed with conventional maize meal, to increase the protein intake of its consumers,” said Marcele.

The production of A. cruentus as a grain crop in South Africa is a relatively new development.

In her research, exploring the possible threats to crop production and paying particular attention to dominant plant pathogens in the Amaranthus cruentus, Marcele found a correlation between fungal pathogens and insect pests. 

Insect pests can influence plant diseases

Although reports on fungal pathogens and pests specific to A. cruentus are limited to and information for South Africa is limited to this study, there is a possibility that by controlling insect pests such as weevils, one might also be able to control fungal pathogens of Amaranthus cruentus.

Marcele believes that control of weevil pests should thus be the focus of future pest and pathogen management strategies and breeding programmes in A. cruentus.  

“Knowledge gained in my thesis will hopefully aid in the development of future cultivation practices, integrated pest/pathogen management programmes, as well as for the registration of crop protection products for A. cruentus,” Marcele added.

Odeion String Quartet receives international acclaim
2014-12-22

 

The Odeion String Quartet (OSQ) is a flagship of the UFS and symbolises the university’s commitment to the arts. Most recently, the OSQ walked away with the award for Best Classical Music Performance at the 2014 Kanna ceremony.

It was established in 1991 as a permanent full-time resident string quartet –   at present the only resident string quartet at a South African university – and functions as an independent academic department at the UFS.

The members of the quartet are Samson Diamond (leader and first violin), Sharon de Kock (violin), Jeanne-Louise Moolman (viola) and Anmari van der Westhuizen (cello). They have an extensive national and international background and are highly regarded in music circles as soloists and chamber musicians. The members of the quartet play an important strategic role in the development of symphony orchestra music and in classical music training in the Free State. They are exemplary teachers and attract students from all over the country. The Junior Odeion String Quartet and Odeion Sinfonia provide a unique chamber music training experience to selected students.

They regularly perform to critical acclaim in all the major music centres in South Africa, as well as in SADC countries such as Zimbabwe and Zambia. During 2013 they performed at concerts in Belgium, Germany and Switzerland, where they received standing ovations and very positive reviews.

The quartet is also set on giving back to musical communities around the country, with workshops offering guidance on playing techniques and life-skills that are essential for young people who intend to pursue a career in the music sector.
