To Effect of seed priming with fertilizer elements on germination duration of quinoa (Chenopodium quinoa willd) seedlings under drought stress, factorial experiment with completely randomized design with four replications was conducted in Seed Physiology and Technology Laboratory of Shahed University, Shahed University in 2017 year . Experimental factors include: drought stress (0, -3, -6, -9, - 12) times and seed priming with 8 elements (control, hydro, Fe, Zn, Fe + Zn, Nano-Fe, Nano- Zn, Nano- Fe +Nano-Zn), Drought stress levels were calculated using PEG 6000. For seed priming with nutrients used: Fe from Fe sulfate amount of 4 in 1000, and nano form, from Fe - nano oxide amount of 1 in 1000 , and for Zn from Zn sulfate amount of 3 in 1000 and nano form, from Zn- nano oxide amount of 1 in 1000 . And to apply hydropriming treatment , seeds were immersed in distilled water at 25 ° C for 24 hours and subjected to drought stress for two weeks. The results showed that the effect of seed priming treatment with nutrients significant differences were found for all traits at 1 level. Maximum mean of germination duration in pre-treatment nano-Fe fertilizer under -12 bar conditions and also the lowest mean of germination duration was observed in control fertilizer pretreatment under drought stress conditions - 12 bar.
