How does radiation affect seed growth?

Answer

This depends largely on the type of radiation that the seed is exposed to, how much it is exposed to, and for how long. It also depends on if the seed, water, or soil receives the radiation. Ultraviolet rays from the sun are a type of radiation. There have been numerous experiments with radiation and seeds, with microwave ovens being the most commonly used source of radiation. The results generally show that some radiation will cause the seeds to germinate and grow faster while a high dose of radiation will cause no growth at all. Mid-range radiation may cause faster germination, but overall growth is shorter than seeds that germinated naturally.

Seeds are covered by a hard seed coat, which must be softened by water before germination can occur. If the seed is too dry, it will never germinate and may eventually die. However,

In order to determine how radiation affects the growth of seeds, first you need to determine how much radiation is involved. Everything on earth is exposed to minimal amounts of radiation, which has no direct affect on seeds. However the higher the dosage could cause various affects from slow seed growth to none at all. But in order to have this type of affect, the seed must be exposed to a very high dose of radiation. You can perform your own test. Take seeds of the same time, place each amounts on a wet paper towel and place towel on paper plant. Place the test seeds in the microwave on different intervals such as 10 sec, 20 sec, and so on to a minute. Make sure to keep the paper towel wet. One set will not be microwaved at all. Cover each set with a plastic wrap and place in a lighted area. Uncover a few minutes a day to allow the circulation of fresh air. Watch over the next few days to see which seeds sprout first of the microwave seeds. Compare the growth of seeds exposed at different levels to the seeds without exposure.
