Dr Dennis Greer

BSc(Hons), PhD

Dr Dennis Greer completed his PhD at the University of Otago in 1979 and commenced a research career in horticulture at the Horticulture and Food Research Institute and carried much research at the National Climate Laboratory.  Whilst there, Dr Greer had a Visiting Investigator grant at the Department of Plant Biology, Carnegie Institute of Washington in Palo Alto California in 1984 and was also awarded an OECD Scholarship in Photosynthesis in 1989 to work at the Department of Plant Physiology, University of Umea, Umea Sweden.

In 2002, Dr Greer was appointed to the School of Wine and Food Sciences, Charles Sturt University to teach viticulture and wine science students and in 2005 was involved in the successful 'Winegrowing Futures' grant to the National Wine and Grape Industry Centre (2006-2011).

In 2012, Dr Greer went on Special Studies leave to the Department of Speciality Crops, University of Hohenheim in Stuttgart, Germany and spent 5 months there researching the effects of nitrogen and source-sink effects on the photosynthetic processes of apple tree leaves.

Specialisation: Grapevine physiology

Focus Area: Abiotic stresses, berry ripening, vine carbon balance

High light intensities and high temperatures can interact to influence vine performance and berry ripening as well as reduce the acquisition of carbon through photosynthesis impairment. Research has been conducted with covering vines with shade cloth or spraying with water to control leaf temperature and as methods to investigate how extreme light and temperature conditions impact on the mechanisms of supply and demand between vegetative and reproductive growth. The use of controlled environment conditions are an essential tool to uncouple temperature and light effects on vine and investigate the mechanisms underpinning growth and development of vines and berries.
