A series of experiments to determine the effects of microgravity on growth and development of wheat were conducted during a 73-day period onboard the International Space Station. The experiment relied upon telescience for the remote operation, monitoring, and management of the experiment. Growth and development of wheat was measured directly by the ISS crew, estimated from analysis of telemetry data, and quantified with digital image analysis. On-orbit germination rates of stowed root modules containing seed cassettes were greater than 95%. Absolute growth rates of ~4.25 cm per day were observed in both the flight and ground control plants. Final height of plants on orbit was approximately 10% greater than comparable ground controls. The results suggest that early growth and development of wheat can be consistently achieved in long-duration space experiments.
