The Genotoxic Effects of Logran on Hordeum vulgare L. and Triticum aestivum L.

In the present study, the cytogenetic effects of the herbicide Logran on root tip cells of Triticum aestivum L. and Hordeum vulgare L. and changes of total protein content in root tip meristems were studied. The seeds of plants were treated with various concentrations of Logran (125, 250, 500 µg/ml) for 3 and 6 h. The percentages of abnormal cells were seen to increase with increasing treatment period and concentrations. The most dominant types of observed abnormalities were C-mitosis, distributed metaphase and anaphase, stickiness. All the used concentrations of Logran significantly induced a number of chromosomal aberrations in root tip cells of Hordeum vulgare L. and Triticum aestivum L. Logran also decreased mitotic index. The decrease of protein content in root tips of Triticum aestivum L. is significant at all the treated concentrations and treatment periods when compared with control.
