Effect of auxins
• [IAA] stimulates shoot growth but inhibits buds opening.
• IAA is produced at the tip of the plant and is transported
downward.
• The high concentrations near the apex inhibit lateral buds
opening.
• As the concentration decreases it frees the buds from the
inhibition and they develop. (growth response in low
concentration).
