Studies on the Effects of  Intermittent  Irradiation on  Nuclear  Aberrations  of Root Tip Cells in Vicia faba

Abstract

Abstract: This experiment aims to compare the effect of intermittent irradiationand that of continuous irradiation on dry seeds of Vicia faba by 60Co-γ-rays. Experimental results show that intermittent irradiation possess lower damage, higher frequency of chromosomal exchange than continual irradiation. It implied that, living cellsstill have some ability to repair radiant damage, when exposed intermittently to radiation in 0.5-2 hours. The repair ability declines as the dosage increases and tile interval of radiation shortened.

Key words: Intermittent irradiation, Nuclear aberrations, Vicia faba
