A.cepa seeds were used as test material. Germination percentage, root lenght and weight gain was used as physiological indicators and chromosomal damage, micronucleus (MN) frequency, mitotoc index (MI) was used as cytotoxicity indicators and these datas were correlated with statistical parameters. The seeds of A.cepa were divided into three groups: control (Group I) and 1,4 Dioxane treatment groups. Group II and Group III were treated with 50 ppm and 100 ppm 1,4 Dioxane, respectively for 72 hours. As a result, it was determined that Dioxane fairly decreased the germination percentage, root length and weight gain depending on dose in seeds all treatment groups, whereas chromosomal damage and MN rate was increased. In conclusion, data obtained in this study indicated that 1,4 Dioxane has a dose dependent cytotoxic effects on root tip cells of A.cepa.</p></abstract>
