Action of Auxin on Protoplasmic Streaming


STUDIES on the mechanism by which auxin exerts its growth-promoting action on plant cells have indicated that, although ultimately detectable on the cell-wall, the effect is exerted in the first instance on the protoplasm. The results of Bonner1 established a close connexion between growth and respiration, although pure auxin was not found, either by him or by van Hulssen2, to increase respiration appreciably.
