What Happens When A Seed Germinates by Beate Schwirtlich
The whole purpose of starting seeds indoors is to cheat winter a little.
Ironically, even as we cheat nature, we must imitate her. Light, soil, water, air, and a basic understanding of the process of germination are all you need. Once you know the simple things a seed requires, starting them indoors won’t seem half as complicated.
Seeds are their own energy source, a plant in embryo form. They store energy in a form that is released and used only when water, oxygen, soil, and a close-to-ideal temperature are a part of their surroundings.
Until then, they remain dormant. Germination inhibitors are part of the make-up of every seed. They actually prevent a seed from germinating until its chances of survival are good. Usually chemical in nature (five per cent of seeds are simply waterproof, dormant until their seed coat cracks), germination inhibitors put a seed into dormancy. Without these, a tomato seed, for example, would spout right inside the fruit of the plant that formed it, where there is moisture and warmth, good conditions for germination. Inhibitors give a seed time to travel away from the parent plant, and allow it to overwinter, or be stored, giving that seed the best possible chance to reproduce successfully and to spread. Germination inhibitors `wear off’ over time, allowing a seed to sprout the next year.
