Abstract


Higher plants strongly interact with their atmospheric and terrestrial environments and are expected to be affected as a results of their exposure to nanoparticles. In this study, the effects of different concentrations of nanized CuO on seed germination , seedling growth and photosynthetic pigments of chicory were investigated in a randomized completely design with four replications.The experimental treatments included four concentrations of nanized CuO (10, 50 ,100 and 500ppm ) and control without any Cu. Results indicated that among the chicory germination indices, only germination percentage and weighted germination index was affected by nano CuO treatments. All of nano CuO treatments increased chlorophyll and carotenoids contents but had no significant difference. It is concluded that treatment with nano CuO treatments have no effects on germination indices and photosynthetic pigments of chicory in comparison to the control.
