Dwarf plants are useful in research because multiple plants or plant communities can be grown in small growth chambers. We have studied a gibberellic acid (GA) mutant of rice (Oryza sativa japonica cv. 'Shiokari' line N-71) that is extremely dwarf (20-cm tall). Unfortunately, this GA mutation is associated with poor germination (70%) under aerobic conditions. Neither exogenous GA, nor a dormancy-breaking heat treatment improved germination. However, excellent germination (95%) was achieved by germinating the seeds anaerobically, either in a pure N2 environment or submerged in unstirred tap water.
