Abstract

In order to investigate the effect of foliar application of selenium nanoparticles on reducing the negative effect of drought stress on Echinacea pupurea cultivar Rose Carmine, a split-plot research was conducted in the form of a completely randomized design with three replications in the greenhouse of Urmia University's Faculty of Agriculture. Drought stress treatments (main treatment) were applied based on the agricultural capacity of the soil and at four levels of 20, 40, 60 and 100% of the field capacity by measuring soil moisture at the root depth and using TDR device. Selenium nanoparticles treatment (sub-treatment) also simultaneously with the application of different levels of drought stress, in the form of foliar spraying and at four levels of zero (control), 5, 10 and 20 mg/liter and with two-week intervals and in one The three-month period was applied. The results showed that the maximum fresh weight of the shoot in the stress treatment of 40% of the agricultural capacity with 10 mg/liter of selenium nanoparticles,the lowest amount of malondialdehyde accumulation in the treatment of 20% of the agricultural capacity with foliar spraying of 5 ml g/l without spraying was observed. According to the general results of the study and examination of other traits, it was found that nano-selenium foliar application has been able to increase the resistance of the plant in stress conditions and has a positive application, and as a result, the performance and vegetative growth traits are significantly affected by the levels Irrigation and foliar treatment have been placed.
