The average median tail moments in leaf nuclei of N. tabacum plants cultivated for 8 weeks in soil polluted with aqueous solutions of AgNPs and AuNPs (size AgNPs1 12–15 nm and AgNPs2 22–25 nm, AuNPs1 12–15 nm and AuNPs2 22–25 nm). The plants were cultivated at 22–28 °C in a plant growth room with a 16 h photoperiod. The error bars represent the standard error of the mean. (*) Significantly (p < 0.05) different values comparing to the control.
