Oryza longistaminata
Oryza longistaminata
Safety & Hazards
None known
Cultivation Details
Requires a sunny position[1]. Prefers black cotton soils, Kalahari sand, and alluvium. Plants can succeed in water up to 4 metres deep, but generally it is less than 1 metre[1, 2]. The plant can become a noxious weed in rice paddy fields, suppressing cultivated-rice strains[1]. Plants can flower at any time of the year[2]. The plant does not always set seed well, propagating itself mainly by means of its extensive rhizomes[3].
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[2]. 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[2]. Surface sow the seed in light shade and do not allow to dry out. Seed should germinate within 7 days at 30°c[2]. 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. Division.
