Abstract
Activity of Cu2+-diamine oxidase (DAO; E.C.1.4.3.6.) was measured in Vigna radiata (L.) Wilczek cultivars K851, MH8320 and Pusa Baisakhi in light and in dark during ontogeny of seedlings. DAO activity was always the highest in cv. K851. In both light and dark grown seedlings maximum DAO activity was detected on day 2 after germination. Thereafter, in light grown seedlings it declined consistently upto non-detectable levels. In dark, DAO activity was higher than in light and it had the second maximum on day 7 following a similar declining pattern as observed for the light grown seedlings. The DAO activity was higher in a shoot apex alongwith leaves than in roots and shoot axis.
