The metabolism of gibberelline (GAs) in intact plants of Raphanus sativus was investigated. With [2H]GA feeds, [2H]GA1 from [2H]GA4, and [2H]GA4 and [2H]GA20 from [2H]GA9 were metabolized. Since [2H]GA20 was not converted into [2H]GA1, endogenous GA1 may have been biosynthesized form GA9 via GA4 rather than from GA20. The radioactivity of [3H]GA9 and [3H]GA20 was much more strongly transported among the plant organs than that of [3H]GA1 and [3H]GA4
