Cytogenetic effects induced by hexanitrogen-cobaltiat III of sodium on mitotic division at Triticum aestivum L.

Abstract

The paper presents the influence of hexanitrogen-cobaltiat III of sodium upon the cellular division at Triticum aestivum L. The treatment with hexanitrogen-cobaltiat III of sodium in three concentrations: 5%, 1%, 0.1% for 4 hours and 2 hours of on wheat radicular meristems were expressed by chromosomial mutations, especially in ana-telophase: chromosomal bridges, little chromosomal fragments and retardatary chromosomes, multi-polar ana-telophases, many micronuclei, whose rate was differentiated depending on the concentration function and time of action of respective chemical agent. Frequently chromosomial aberrations induced by hexanitrogen cobaltiat III of sodium are bridges very thick who determine citomixia phenomenon. Also, hexanitrogen-cobaltiat III of sodium induced many micronuclei and picnotic nuclei non-functional. Hexanitrogen-cobaltiat III of sodium has a strong inhibitory effect on mitotic division of Triticum aestivum L. Particularly metaphase and anaphase are inhibition. The experiment proved that hexanitrogen-cobaltiat III of sodium, known as a polluting agent has a mutagenic potential on the plants.
