Summary

The efficiency of caffeine at different concentration on the induction of binucleate cells in onion root-tip was studied. The drug effect is strongly depressed in the Ca++ and/or Mg++ presence at half-rate of maximum efficiency (0.04%), about 2 mM). We therefore conclude that both cations must play a role in plant cytokinesis.
