Abstract
Since ionizing radiation has been shown to produce free-radicals in dry seeds, effect peroxidation of lipids in model systems, and cause changes in membrane permeability, it was decided to subject dry seeds of lettuce to gamma irradiation to determine whether the cytological changes which occurred on subsequent imbition are similar in any way to those occurring during natural ageing in dry storage. Seeds of 3% moisture content were radiated with gamma rays from a Cobalt 60 source at doses between 3,4 kGy and 23,8 kGy and the root tips prepared for TEM after 5 and 12 hours imbition. The cytological changes which occurred are shortly discussed.
