Abstract

Future space crop production systems will require that plant health and food safety is determined with minimal crew intervention. A prototype hyperspectral and chlorophyll fluorescence imaging system was designed for early symptom detection of abiotic plant stress in crop production systems. A watering system was developed for imposing water stress treatments (mild or severe drought, flooding) on candidate leafy green crops to be grown on the International Space Station. Daily images recorded changes in crop reflectance and chlorophyll fluorescence during 28-day growouts. Harvest data recorded leaf area, fresh weight, dry weight, plant height and leaf number. The imaging and harvest data were used to evaluate the ability of the prototype imaging system to differentiate between the water stress treatments.
