| Plant Biology Applications | Auxins are used in plant tissue culture to modulate general root and shoot architecture, organ patterning, vascular development and growth in tissue culture and tropic responses to light and gravity. IBA is typically used to induce rooting when propagating plants by striking or cutting. In addition, IBA has proven to facilitate fruit ripening after absorption into the plant. In one study, IBA was shown to promote adventitious rooting (roots forming in atypical locations) in Arabidopsis stem segments (Town, 2005). |
