[Peculiarities of the influence of chemical and physical factors on cytogenetic indices of root meristem in Pisum sativum L].
The results of comparative analysis of cytogenetic effects of various chemical and physical factors on meristemic cells of field pea (Pisum sativum L.) are presented. Cytogenetic effects of aluminum, cadmium and selenium compounds as well as X-ray irradiation were studied. Cytogenetic indices were investigated for different doses of the above factors and peculiarities of their influence on the ratio of mitotic phases were analyzed. The increasing in the proportion of cells at the specific mitotic stage was revealed. There were anaphase stage for aluminum chloride, prophase stage for cadmium chloride, meta- and anaphase stages for sodium selenate, and telophase stage for X-rays. Investigated chemical elements may be ranged according to their ability to induce the aberrant anaphase frequency in the row: Se (from 3.75 x 10(-6) M) > A1 (from 3.86 x 10(-5) M) > Cd (from 8.44 x 10(-5) M). Maximal experimental dose of X-ray irradiation (9.03 x 10(-3) C/kg) induces the frequency of chromosome aberration similar to those induced by maximal experimental doses of aluminum and selenium (3.86 x 10(-4) M and 8.34 x 10(-6) M).
