Indoleacetic acid, tryptophan and indole promote growth of pith tissues of tumorous Nicotiana glauca × N. langsdorffii amphidiploïd hybrid, but only indoleacetic acid gives the potentiality of continuous development to the tumorous tissues after some days of contact on a medium without growth substances. In combination with 6‐benzylaminopurine, tryptophan and especially indole are promoting substances like auxin for the non‐tumorous pith tissues of tobacco, and allow a considerable organogenesis.
