What are the 6 stages of germination?
- Step 1: Imbibition: water fills the seed.
- Step 2: The water activates enzymes that begin the plant's growth.
- Step 3: The seed grows a root to access water underground.
- Step 4: The seed grows shoots that grow towards the sun.
- Step 5: The shoots grow leaves and begin photmorphogenesis.
How much water do you need to germinate a seed?
Seeds require water for germination. There is no set water requirement, and they need enough moisture to break down the seed coat and allow the embryo to start germinating. The ideal moisture content of seeds is at least 85%, which means that if you keep your seeds in a container with 95% humidity, it would be perfect.

Some seeds, such as morning glory, nasturtium or locust seeds, have a hard seed coat that is slow to break down. Soak these seeds overnight in warm water to soften the seed coat. Drain and plant them for faster germination. Many people soak bean seeds, which is not necessary and may cause the seeds to rot and crack.
What Causes Seed Germination?
The process of germination is when a seed comes out of dormancy, the time during which its metabolic activity is very slow. Germination begins with imbibition, a big word for taking in water. This is the major trigger to start the period of waking up from dormancy.
What are the factors that determine seed germination?
Of all the factors that determine seed germination, water is the first and most important. Without water it cannot happen and a seed will stay dormant. But too much water and a seed will rot. Soil should be moist but not soaked. Drainage is essential.
How does soil depth affect seed?
Soil depth also varies, depending on seed size. A seed has a set amount of energy stored, and if it uses it all up before the cotyledons reach the surface and can access light, the seed will fail. Larger seeds need more depth to get rooted. Seed packets will provide the depth information.
What are the requirements for germination?
Specific seed germination requirements vary depending on the plant species. But they generally include water, air, temperature, and ultimately access to light.
