In order to investigate the effect of nano fertilizers on germination of experimental Linum usitatissimum oil in a factorial design with completely randomized design with three levels of titanium dioxide (۱۰, ۵۰ and ۷۵ mg /L), three levels of iron nano oxide (۲۵, ۵۰ and ۷۵ mg/L) and nano silicon dioxide at three levels (۱۰, ۵۰ and ۷۵ mg/L) in ۳ replications in ۲۰۲۰. The results showed that treatments had significant effect on germination percentage, germination diameter and number of germs at ۱% probability level but no significant effect on germination rate, germination index, seed vigor index and germination length. The highest germination percentage, number of bud and diameter of shoot were observed in titanium dioxide treatment. Overall, among the nanotreatments used, titanium dioxide nanoparticles at ۱۰ mg/L increased the properties studied. According to the results of this experiment, application of titanium dioxide on flaxseed can provide faster germination and stronger seedlings.
