چکیده مقاله :

In this study, the effects of different concentrations of bulk and nano-sized Ag on seed germination and seedling growth of canola were investigated in a randomized completely design with four replications. The experimental treatments included four concentrations of bulk AgNO3 (10, 100, 500 and 1000 ppm), four concentrations of nanosized Ag (10, 100, 500 and 1000 ppm), and the control without Ag. Results indicated that among the canola germination indices only mean germination time and germination index were not affected by treatments. The TTC tests showed all root tips were colored red. It is concluded that bulk AgNO3 treatments inhibited germination indices of canola more than nano sized Ag.
