Oryza sativa is a semi-aquatic cereal grass native to Southeast Asia. Unlike other crops, rice can germinate under hypoxic (low oxygen) conditions and is traditionally grown in flooded fields. It is a staple food for more than one-third of the world population.
Before sowing
Pre-soaking for 24h or seed priming (24-48h soaking followed by drying) improves seedling establishment under stress

What to expect
Tips
Rice germinates readily at 20-30°C; germination at 30°C optimal with 85% germination rate. Red light enhances germination (98%) compared to other light colors. Seeds can tolerate flooded conditions during germination. Intact seeds may show better germination than dehusked seeds depending on cultivar.
