Abstract
In glasshouse trials, soyabeans were grown from seeds irradiated with X-rays at intensities of 250, 500, 1000 or 2000 rad under continuous light, or after the first 3 weeks were exposed to 7 short-day cycles (8-h light/16-h darkness) and were then returned to continuous light. X-ray irradiation stimulated floral initiation only under short-day conditions. In a 2nd trial, seeds of 2 sorghum cv. and their hybrid were irradiated with X-rays at the same intensities as the soyabeans and were grown under natural daylength conditions in summer. Flowering was accelerated at all rates of irradiation in the hybrid, but was retarded except at 250 rad in 1 parent and at 2000 rad in the other. Irradiation at 250 and 1000 rad, but not at 500 and 2000 rad, increased plant height of the hybrid.
