comparisons with zeatin , 6-benzylaminopurine and kinetin indicated that , although the maximum growth rates obtained with relatively high concentrations ( 0.1-1 mum ) were similar , the naturally occurring cytokinins , 2ip and zeatin , promoted faster rates at lower concentrations ( 10 ( -3 ) -10 ( -2 ) mum ) than did 6-benzylaminopurine and kinetin .
