Цитогенетические изменения в апикальной меристеме корня кукурузы при действии ионов никеля
Cytotoxic effects in maize root’s apical meristem under the nickel ions influence

Summary/Abstract: Effect of different concentrations of nickel ions (10 - 4, 10 - 5 and 3.4 × 10 - 6 М × l - 1) on the root growth and apical meristem cell division in the seedling of Zea mays L. has been studied. Peculiarities of the nickel ions cytotoxic effect was estimated by the mitotic index, index of aberrations and pycnotic nuclei changes. Toxicity of the nickel ions for the maize meristematic tissues is ascertained.
