Resumo
The degree of radio sensitivity depends mainly on the species, the stage of the embryo in the irradiation, the doses used and
the criteria used to measure the effect. One of the most common criteria for evaluating seed radio sensitivity is to measure
the plant's average yield. The dried soybean seeds were exposed to low doses of gamma radiation from Cobalt-60,
Gammacell-220 type source, at a dose rate of 0.245 kGy. In the first stage the objective was to study the effects of radiation
stimulation on germination, growth and plant production. Four doses of radiation were applied as follows: 0 (control); 25;
50; 75 and 100 Gy. Seed germination harvested seed number and total yield were evaluated to identify the occurrence of
stimulation. The low doses of gamma radiation in the seeds that stimulate the production were doses of 25, 50 and 75 Gy. In
the second stage the objective was also to study the effects of radiation stimulation on germination, growth and plant
production. In this case, a treatment with three doses of radiation was applied as follows: 0 (control); 12.5; 25.0 and 50.0 Gy.
Seed germination harvested seed number and total yield were evaluated to identify the occurrence of stimulation. The
number of soybean seeds and plants were handled following the standard seed production in Brazil. There is evidence in the
results showing that the use of low doses of gamma radiation can stimulate the germination and the production of plants.
