Abstract

Crystalline abscisin II, with a tentative molecular formula of C₁₅H₂₀O₄, has been isolated from young cotton fruit. It accelerates abscission when applied in amounts as low as 0.01 µg per abscission zone. It inhibits indoleacetic acid-induced straight growth of Avena coleoptiles but has no gibberellin activity on dwarf maize.
