摘要:The genotoxicity of the pesticide Folpan was evalua ted in meristematic root cells of Tulipa gesneriana cv. 'Leen van der Mark'. The statistical analyses of the results showed that the pesticide studied has a concentration-dependent toxicity and indu ces chromosomal aberrations. The lowest mitotic index (2,69%) was related with the highest tested concentration of Folpan (900 ppm). Various types of chromosomal and mitotic abnorm alities such as binucleated cells, laggards, and disturbed ana-telophase with multiple chromosomal bridges revealed the clastogenic potential of pesticide tested
