Abstract
The treatments of barley seeds with plant growth regulators induced effects whose amplitude, analyzed in the dynamics of the three quantitative determinations, was in relation with the type and concentration of tested compound and also with the seedlings age. Auxin slightly stimulated seedlings growth, kinetin and 2,4-D+Kin mixture inhibited their elongation in all tested concentrations, while the treatment with gibberellic acid generally expressed in increase of barley seedlings lenght. Mitotic index had no significant variations comparatively to control. Ana-teophase chromosome aberrations were present in a percentage that surpassed the control average in several variants subjected to the treatment with growth regulators: 10 mg l-1 and 25 mg l-1 2,4-D; 1 mg l-1 gibberellic acid; 1 mg l-1 2,4-D+ 1 mg l-1 kinetin.
