Characterisation of Microseris lanceolate – tuber and daisy

Microseris lanceolate, also referred to as yam daisy, is an Australian native perennial plant that consists of a yellow daisy and a tuber. It is reported to grow in a range of habitats, including very low nutrient soil, and has a low water requirement. The tuber has a history of use as a staple food for indigenous people and anecdotal evidence suggests that the daisy contains anti-herbivory compounds, effective on native species.
It is proposed that the yam could provide a local source of starch. While the focus is on the starch content, other components of the tuber will be assessed, also as potential resources.
Plant defence mechanisms can involve the production of secondary metabolites including alkaloids. If the daisy contains appreciable levels of these compounds, there may be an application for natural crop protection.
Project objectives
The objectives of the project are;
1. Complete a desk top analysis of the composition and uses of the yam tuber and daisy.
2. Evaluate the chemical properties of the tuber.
3. Evaluate the alkaloid content of the daisy.
4. Based on 1 to 3, recommend potential use options and requirements for proof of concept.
