Effect of Peganum harmala extract on root tips of Allium cepa.
Treatment with Peganum harmala extract remarkably increased the mitotic index in Allium cepa root tips with increasing treatment duration at all exposure times used and with almost all concentrations. The extract caused a relatively high increase in the mitotic index after a long period of treatment with some low concentrations.
