镉·硒单一及联合作用对大蒜根尖细胞微核的影响
Individual and Combined Effects of Cadmium and Selenium on Micronuclei of Allium sativum
摘要
Abstract
[Objective] The aim was to study the individual and combined effects of cadmium and selenium on the micronuclei of Allium sativum. [Method] We determined the root growth rate and the micronucleus rate. [Result] The Cd (1. 0-200. 0 mg/L) had toxic effect on garlic root. The root growth was inhibited and the cell micronucleus formed after Cd treatment. The degree of Cd poisoning on root increased as Cd concentra-tion increased. Under the combined treatment of Se and Cd, the micronucleus rates of combined treatments with a low concentration (<0. 5 mg/L) of Se were lower than the sole Cd treatment. However,the high levels of Se (>0. 5 mg/L) could increase the damage of Cd on root tip of garlic. [ Conclusion] Se can relieve the toxic effect of Cd on garlic root under low concentration and aggravate the toxic effect under high concentration.关键词
