Abstract
NUMEROUS investigators have reported that when seeds are soaked there is a parallel increase in their water content and sensitivity to X-rays1. These studies have been taken as strong support for the postulate that much radiation injury results ‘indirectly’ from the decomposition and/or ionization of water. Therefore, it was of some concern to us when it was shown there was actually an inverse relationship between the water content of dormant barley seeds and their sensitivity to X-rays2. For this reason it seemed desirable to re-investigate the relation between radiosensitivity and the water content of soaked seeds.
