Other claims from this paper (6)
- Observation Seeds were dormant at maturity in September and became non-dormant during winter.
- Observation Seeds buried in non-flooded soil retained the ability to germinate in light at high temperatures under flooded conditions throughout the summer.
- Observation Seeds can potentially germinate at any time during the growing season whenever rice fields are flooded.
- Recommendation Flooding fields in winter and/or sowing rice early may help establish rice before H. limosa seeds germinate.
- Observation The water regime associated with rice culture is optimal for germination of H. limosa seeds.
- Observation A portion of buried seeds exhibited an annual dormancy/non-dormancy cycle, while others had a conditional dormancy/non-dormancy cycle.
