Small doses of X-ray may stimulate cellular activities and growth while higher doses may cause higher aberrations. Seeds of Arachis hypogaea cv Kampala were exposed singly to X-ray radiations (6 mA-77 mA) X-ray significantly decreased seed germination above 6 mA, reduced root and shoot growth as X-ray exposure increased. X-ray radiation causes chromosomal aberration. Therefore, higher X-ray radiation affects the plant germination negatively by retarding the growth
