Abstract
Polar indole-3-acetic acid movement was observed in killed plant segments and in artificial model systems. The polar diffusion of indole-3-acetic acid was observed in tissue killed by chemical or physical means in an agar-plant system and in a multicelled Plexiglas dialysis chamber containing hypocotyl tissue gradients or gradients of anion exchange material.
It was suggested that polar indole-3-acetic acid movement in excised segments may be a reflection of the diffusion of indole-3-acetic acid through asymmetric gradients of materials with binding characteristics somewhat similar to ion exchange.
