The size, activity and maintenance of the shoot apical meristem (SAM) are defined by a balanced rate of mitotic cell divisions and functional cell differentiation that are controlled by cytokinins. In order to investigate the effect of exogenous cytokinin on SAM, morpho-anatomical changes in the shoot apices of tobacco treated with benzyladenine (BA) were compared to those of untreated control plants. %K Benzyladenine %K histology %K shoot apical meristem %K tobacco %U http://www.doiserbia.nb.rs/img/doi/0354-4664/2012/0354-46641202511U.pdf
