“…Therefore, they concluded that the cell wall was the primary barrier to water uptake. Burstrom and Fransson (1957) decided from studies of water-saturated Avena coleoptiles that permeability could not limit auxin induced elongation even if there were no restriction on water uptake. It appears from the work of Burstrom The possible effects of auxins on the synthesis of wall components have also been studied extensively.…”
