Abstract
Maize seeds of the single cross WF 9 x 38-11 were irradiated with pile neutrons with doses ranging from 1 x 1012 Np to 5 x 1014 Np and then treated with gibberellic acid (GA). In 1 set of experiments the seeds were soaked in GA for 24 hours and raised in sand. In another set they were sprouted in water, and seedlings with a 2-3 cm root-length were from then grown on in GA solution. It was evident from both these experiments that GA can reverse the stunting of seedlings caused by radiation.
