The purpose of this research was to investigate pistachio seed priming and seedling spraying using the organic amino compound "Cheshmgir" on the germination and growth characteristics of pistachio seedlings. The first experiment was to investigate the effect of seed priming treatment (organic amino compound 5 per thousand) on germination in laboratory conditions. In the second experiment, the effect of spraying organic amino compounds was investigated on 3 and 5-month-old seedlings. This experiment was conducted in a completely random statistical design with 6 treatments and 6 replications. In the third experiment, the combined effect of priming and spraying of this combination was evaluated on the growth traits of seedlings in hydroponic culture under greenhouse conditions. This experiment was conducted as a factorial in a completely randomized design with 6 treatments and 6 replications. In this experiment, the growth characteristics of seedlings were evaluated, The results of the first experiment showed that the highest germination speed and the length and weight vigour index of seed were in Qazvini seeds, which were increased by 10, 273 and 230%, respectively, in comparison with Badami-e-Zarand seeds. Seed priming with organic amino compound 5 per thousand significantly increased the average rate of germination (44.8%) and root growth (54.7%). The results of the second experiment showed that the concentration of 5 per thousand in 3-month-old seedlings had a significant effect on increasing the number of leaves (50.9%), increasing the root volume (3%) and reducing the number of damaged leaves (100%) compared to the control. The results of the third test based on the DOE experimental plan showed that the best level of response with the highest efficiency and efficiency was related to the application of 5 per thousand foliar spraying of amino organic compound (during 3 times with intervals of 25 days) along with seed priming.
