In this study, whether lycopene has preventive effect on chromosome aberrations or not was investigated. For this purpose, 2 different concentrations (0.02 and 0.03 M) of Ethyl Methane Sulfonate (EMS) which is known to induce chromosomal damage were treated on Allium cepa for 2 h. Afterwards, plant roots were treated with lycopene extracts in 4 different concentrations (1, 3, 5 and 10 μM) for 24 h. 0.02 and 0.03 M EMS were used as positive control and tap water was used as negative control. Root tip meristematic cells were observed under the microscope. Mitotic index (MI) and chromosomal aberrations (fragments, bridges, stickness, polar deviation) and micronucleus formation were evaluated and statistically analyzed. As a result; it was determined that depending on applied lycopene concentrations both in MI and chromosomal aberrations lycopene-caused some changes. It was seen that lycopene had preventive effect on chromosome aberrations particularly at 1 and 3 μM concentrations, but this effect decreased at 5 and 10 μM concentrations. |
