Radiosensitivity of Jack Pine Seed to Cobalt-60
Abstract:Following exposure of Pinus banksiana Lamb. seeds to varying doses of Co60, germination counts, seedling measurements and morphological effects were recorded. Percentage and rate of germination of the seed was reduced following irradiation with Co60, particularly with dosages exceeding 9,000 r/hr. At the higher dosages, morphological effects included: inhibited growth, thickening of the hypocotyl, and a swelling of the seed contents.
