Oryza barthii
Safety & Hazards
None known
Cultivation Details
Requires an open, sunny position. Prefers clay or black cotton soils. Succeeds in deep water, but grows best in shallow water[1]. The plant is often considered to be a weed within its native range, where it is often found growing amongst rice[2].
Propagation
Seed. The seed of wild rice less than 12 months old often exhibits strong dormancy, which implies (though this has not been established) that the seed retains its viability for a considerable period[1]. Heat treatment is generally effective in breaking dormancy - alternating temperatures between 34°c for 16 hours then 11°c for 8 hours is usually effective, though the time taken varies between species[1]. Surface sow the seed in light shade and do not allow to dry out. Seed should germinate within 7 days at 30°c[1]. Prick out 2 - 3 seedlings into individual pots when large enough to handle and, after a few days, move to a sunny position. Grow on until large enough to plant out.
