Abstract

                                High, medium and low vigour seeds of bajra ev. CO 7 were subjected to hydration- dehydration (H-DH) and halogenation treatments to prolong storability under ambient conditions. H-DH exerted excellent effects on medium and low vigour seeds while halogenation treatments conferred best effect on medium and low vigour seeds and to a certain extent or high vigour seeds. The improvement in germination for H-DH was 3. 33 and 50 per cent for high, medium and low vigour seeds and 89, 24 and 40 per cent for halogenation treatments, respectively. The invigoration effect was significantly evident from vigour index value, dehydrogenase enzyme activity and field emergence percentage as compared to control in all seed vigour groups.
