Assessment of Nanotoxicity (Cadmium Sulphide and Copper Oxide) Using Cytogenetical Parameters in Coriandrum sativum L. (Apiaceae)

Abstract

Present investigation deals with cytogenetical consequences (using attributes namely, seed germination, seedling length, mitotic index, mitotic and meiotic abnormalities and pollen grain sterilities) of cadmium sulphide (CdS) and copper oxide (CuO) nanoparticles (NPs) treatment in Coriandrum sativum L. (Family: Apiaceae, spice of commerce). Ethyl methanesulphonate (EMS), a conventional mutagen is used as positive control. Results suggest that both CdS- and CuO-NPs can induce growth inhibition and cause cytological aberrations in both mitotic and meiotic cells in the studied species. EMS also responds similarly as that of NPs. Study highlights that rooted plant species can be effectively used as model for assessment of nanotoxicity considering cytogenetical parameters.
