Effect Of Oxygen Deficiency On Seed Germination
Place some moist soil in each of two one-gallon glass jugs and drop fast-growing seeds, such as radish or squash seed, upon the moist soil. Add a little more soil to just cover the seeds and shake the jug gently so that the surface becomes level.
Unroll a strip of steel wool, moisten it, and suspend it inside one of the jugs by means of a string. Close this experimental jug and the chondral jug with corks or stoppers. The moist steel wool should take up most of the oxygen from the experimental jug.
Keep both jugs under the same conditions of light and temperature. Observe both jugs at regular intervals and make notes of any differences in the germination of the seeds.
