  • Fruit development
  • Drought tolerance and heat stress
  • Plant nutrition

Background

Suzy Rogiers is a principal research scientist with the NSW Department of Primary Industries and she is located at the National Wine and Grape Industry Centre in Wagga Wagga. Her research is focussed on the impacts of heat, drought and unpredictable weather on crop productivity. She has researched water-use efficiency, nutrition and carbon acquisition in horticultural crops with a focus on wine grapes. She has a particular interest in fruit colour, flavour, aroma and nutritional profile in response to environmental conditions (light, temperature, water) and cultural practices (canopy management, orchard floor management, irrigation, nutrition, clonal selection and rootstocks). She is also interested in developing simple, cost-effective and accessible tools to aid in rapid management and harvest decisions.

Qualifications

  • BSc (Honours Botany) – University of Alberta (Canada)
  • PhD in Plant Physiology – University of Alberta (Canada)

Current projects

  • Managing wine pH in a changing climate
  • Nutritional disorders in grapevines
  • Organic berry production
  • Pistillate flower abortion in walnuts
  • Transport and function of potassium in grape berries
