ABSTRACT

In this study, seeds of Triticum aestivum L. (Poaceae) were exposed to 0-100 microg/mL chromium oxide nanoparticles (Cr2O3, Nps) to study the phytotoxic effects on seed germination and seedling growth. It has been observed that 25-100 microg/mL Cr2O3, Nps inhibited the seed germination and seedling growth in concentration dependent manner. The present study suggests that release of Cr2O3, Nps in environment may adversely affect the wheat production.
