Abstract
Differences in the barley varieties have been revealed from tolerance to iron (Fe) and aluminum (Al) ions as well as to their combined effect. Received results allowed to separate barley variety into some (three) groups: the first —Al-toler ant varieties, the second — Al-sensitive ones and third —moderately resistant variety. The increased concentration of Fe had practically no effect on biometric (seed germination energy) and cytogenetics (frequency of chromosome aberra tions and mitotic index) parameters as compared to the reference values. At the same time , iron ion significantly reduces the phytotoxic effect for Al-tolerant varieties in case of these elements jointly present ed in solution.
