Resumo
The degree of radiosensitivity depends mostly on the species, the stage of the embryo at
irradiation, the doses employed and the criteria used to measure the effect. One of the most
common criteria to evaluate radiosensitivity in seeds is to measure the average plant
production. Dry soya seeds were exposed to low doses of gamma radiation from source of
Cobalt-60, type Gammecell-220, at 0.210 kGy dose rate. In order to study stimulation effects of
radiation on germination, plant growth and production. A treatment with four radiation doses
was applied as follows: 0 (control); 12.5; 25.0 and 50.0 Gy. Seed germination and harvested of
number of seeds and total production were assessed to identify occurrence of stimulation. Soya
seeds number and plants were handled as for usual seed production in Brazil. The low doses of
gamma radiation in the seeds that stimulate the production were the doses of 12.5 and 50.0 Gy.
The results show that the use of low doses of gamma radiation can stimulate germination and
plant production.
