abstract：:Many reports discuss plant growth stimulation by exposure of seeds or plants to low doses of ionizing radiation. The reported effects include increased height, weight, growth rate, flowering and yield. The magnitude of the effect(s) is usually small, being about 10% of control values; and the effects often are not rep...
