Abstract
SKOOG and his co-workers1,2 have demonstrated that tobacco pith sections cultured on nutrient agar containing indolylacetic acid undergo considerable cell enlargement. Many mitotic divisions occur which are unaccompanied by cytokinesis, and thus give rise to multinucleate cells. If kinetin (6-furfurylaminopurine) is added to the medium, rapid cell division occurs. For tobacco pith, the gross effect of kinetin is as a cell division hormone and of indolylacetic acid as a cell enlargement hormone.
