Propagation Processing/Propagule Characteristics:

Pre-Planting Propagule Treatments:
Mechanical injury of the caryopis or covering layers resulted in 67% germination.
Pretreatment with potassium nitrate resulted in 47% germination.
Seeds are placed in cold moist stratification for 28 days. Germination occurs at 35D/20N C alternating temperature cycle.
In another study, germination occurs at 30D/15.5N C alternating temperature cycle. Germination was greater in light than dark; and light was equal to dark. Physiological dormancy of seed is overcome by 28 day cold moist stratification treament and germination tempertures of 35D/20N.
