rosemary extract (Rosmarinus officinalis). It was proved that the treatment with this extract upon the barley caryopses had
as effect the stimulation of the mitotic division in the radicle apex of the species and did not lead to important
cytogenetic changes (chromosome aberrations) in the ana-thelophase of the radicle mitoses
