Abstract

The direct addition of indole-3-acetic acid and sucrose into sterile-cultured segments of tobacco pith via micropipettes has induced cell division and vascularization in a specific arrangement below the tip of the micropipette. The histology of this vascularization is described and it is shown that the orientation of the explant on the basal medium influences callus and bud formation.
