Abstract

Mangiferin, a natural phenolic host metabolite was isolated from the leaves of mango cv. Amrapali. Malformation was reproduced by lowering the concentration of mangiferin through defoliation when it was in the range of 38.0 to 41.0 mg g⁻¹ f.w. In vitro growth of fungus Fusarium subglutinanswas inhibited by mangiferin and maximum inhibition was recorded at 10⁻² M. The plant which had maximum number of malformed buds (268) and lowest mangiferin content (9.8 mg g⁻¹ f.w.) contained higher fusarial population and died at later stage.
