Abstract

The biosynthesis of gibberellins in sunflower roots was examined. Exudate from roots of decapitated sunflower (Helianthus annuus) plants continued to show gibberellin-like activity four days after decapitation. Also, incubation of root apices in 2-¹⁴C mevalonate yielded labeled (-)-kauren-19-ol, an intermediate in gibberellin synthesis. The findings are consistent with the premise that roots synthesize gibberellins.
