The psychology of drought stress response in crops

QAAFI Science Seminar (29 April 2014) Dr Scott Chapman Senior Principal Research Scientist, CSIRO QAAFI Adjunct Professor ABSTRACT To develop yield in heat or drought stress conditions, crops must manage water use to both 'keep their cool' and to 'save water for later'. This applies over both short-term (hours) and long-term (weeks) time periods. Some of the ways that plants respond can be described in 'psychology' terms - hare vs tortoise at the crop level, greed vs collaboration at the plant level. Sometimes it is better to just 'go all out' and use the water available. But it's hard to measure the subtle differences between genotypes. New methods to measure these responses include wireless sensors and robots (including RC helicopters) to measure characteristics which inform simulation models in the prediction of new selectable phenotypes. Genetic and environment effects on growth of field crops, particularly where drought dominates.
