Sporelings of the fern Osmunda regalis became increasingly resistant to killing using 60 Co γ rays delivered continuously at 0.96 Gy/h, when the accumulated dose was greater than about 20 Gy. The induced resistance was also demonstrated by subsequently exposing the cells to acute doses, which were less efficient in killing these cells than cells not previously irradiated by a factor of about three. These studies and others now indicate that induced resistance to ionizing radiation is a feature of all photosynthesizing cell types which have been tested.
