National Wine and Grape Industry Centre
Dr Bruno Holzapfel
Senior Research Fellow – Vine Nutrition
Expertise
Vine nutrition, carbohydrate physiology, vine environment and development.
Current projects
- Management of carbohydrate reserve accumulation as a tool for regulating vine productivity and fruit quality.
- Interactions between nutrient uptake and carbohydrate metabolism in vines
Grape and wine composition influenced by vine resources under different environmental conditions.
Question(s)/Topics to explore in the future
- Understanding the restriction of different soil and atmosphere environments (particularly water and temperature) on vine partitioning, nutrient uptake and productivity.
- Investigate the adaptability of grapevines (varieties, rootstocks) to suboptimal environmental conditions and the scope vineyard management to counteract vine performance limitations.
