How Does Temperature Affect Seed Germination?

Answer

Seed germination depends on the temperature for the plant to sprout. Temperature affects seed germination in several ways including if the plant will spout and how long it will take the plant to come through the soil surface. If the soil temperature is too cold, it can delay germination or even stop it. Cooler soil temperatures can cause the seed to rot because of the moisture surrounding them. If the temperature is too hot, seeds will not grow because of moisture loss.
