Germination in rice occurs when the first shoots and roots start to emerge from the seed and the rice plant begins to grow. To germinate, rice seeds need to absorb a certain amount of water and be exposed to a temperature range of 10–40 °C. This breaks the dormancy stage of the seed. When planted into flooded soil, the shoot is the first to emerge from the seed, with the roots developing when the first shoot has reached the air. If the seed is planted in non-flooded soil, the root is the first to emerge from the seed and then the shoot.
