Effect of lunularic acid on auxin-oxidase activity

  • M. C. Mato

Brief Communication


Lunulario aoid was isolated from fresh thalli ofTargionia hypophylla L. This acid was found to enhanoe the destruction of IAA by auxin-oxidase from lentil roots. Such action can explain, at least partially, its inhibitory effect on IAA-induced plant growth.
