Growth and Development of Higher Plants Under Hypobaric Conditions 2002-01-2439
Plant growth experiments were conducted to study the feasibility of growing plants under hypobaric condition. Seeds of rice and Arabidopsis thaliana germinated at 25 kPa total pressure with 5 or 10 kPa O2 partial pressures. Rice plants in vegetative stage grew normally at 50 kPa of total pressure with suitable O2 and CO2 partial pressures, however, their development in reproductive stage was delayed at 50 kPa total pressure. Seed production of Arabidopsis at 23 kPa total pressure with 21 kPa O2 partial pressure was almost the same as that at atmospheric pressure.
