Answer 2

Answer:

Hey Buddy here's ur answer

Any substance that inhibits auxin by competing for the same receptors.

An anti-auxin such as PCIB (p-chlorophenoxyisobutyric acid) is a substance that competes with auxin (growth regulating hormone) for binding sites. It inhibits the function of auxin but does not cause any growth response.

TIBA (tri-iodobenzoic acid) is an inhibitor that blocks permease and the transport of auxin.
