Cytokinin responses of L. japonicus. Cytokinin-induced inhibition of root elongation of L. japonicus seedlings. Seedlings were grown on vertically oriented MS agar-plates containing cytokinin (BA, 6-benzylaminopurine) at varied concentrations, as indicated. After being incubated for 9 days, the average lengths of their primary roots (n ≥ 20) were measured. Photographs were taken for each representative (upper panel), and the resulting lengths of root were plotted against the cytokinin concentrations tested. As a reference, essentially the same experiments were carried out with A. thaliana seedlings.
