Honours projects currently being offered:
Physiological responses of grapevine berries to high temperature
Supervisors
Acting Professor Victor Sadras
Dr Chris Soar
Background
We are working with a Grape and Wine Research Development Corporation (GWRDC) funded project aiming at measuring the effects of high temperature on phenology, yield components and quality attributes of berries in grapevines. In 2006–07 we devised and tested three methods for temperature control in the field, including closed chambers, open 'under vine tents', and bunch blowers. Following these successful tests the systems are now being further developed and will be ready for use in the 2007–08 season. Photographs of the three methods (.PDF 197.8KB)
Aim
To determine the effects of timing and intensity of heat stress on yield components and berry composition in field-grown grapevines.
Techniques
You will acquire skills in environmental monitoring (devices, software), field grapevine physiology and laboratory analysis (eg acidity, sugars).
Stipend
SARDI will contribute 1 to 2 scholarships ($3000).
