To effect of Seed Priming with Nutrients and Drought on Growth Characteristics of quinoa (Chenopodium quinoa willd) seedlings, 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 and dry Significant differences were found for all traits at 1% level. The highest dry weight of seedling in the nutritional pretreatment of the combination of Fe+ Zn under drought stress -3 and the lowest dry weight in the control pretreatment In dry conditions it was -12 bar.. was obtained.
