Extract

In a recent herbicide development program for control of wild oats (Avena fatua), methods of breaking the dormancy of wild oat seed were studied, since it is difficult to obtain seed with a high rate of germination. One of the theories advanced to explain seed dormancy is that the seed coat acts as a barrier to oxygen penetration. If the seed coat prevents oxygen penetration, then it should be possible to break dormancy by placing seed under high gaseous pressure to force gas through the seed coat, and then rupture the seed coat with a rapid release of pressure.
