Plants absorb Se element from the soil and enter it into the food chain as the best source of selenium for humans and animals. In the current research, the effects of selenium (bulk and nano forms) were investigated on the absorption of macro and micro elements and growth characteristics of spinach under greenhouse conditions. The experiment was carried out in a completely randomized design. The factors were foliar spraying of nano selenium (5, 10 and 20 ppm), sodium selenate (5, 10 and 20 ppm) and distilled water (control plants). Based on the findings, an improvement was observed in root dry matter, shoot length, leaf number, and Ca and Se contents with increasing the levels of treatments, in contrast, high levels of both treatments declined the content of leaf nitrate, Na and Mn. Leaf dry matter and P and Mg contents were boosted at the level of 10 ppm of both treatments, and lessened at higher levels. The highest root length and Fe and Zn contents were observed at 5 ppm of nano-Se. This indicates the additive effects of low Se concentrations on root tip meristem cell division as well as plant water relations via transport of essential elements. However, the reduction of the mentioned traits occurred at higher levels of both treatments (20 ppm). Eventually, among the different levels of both Se treatments, the best one was 10 ppm Nano-Se. However, it can be stated that selecting the best treatment depends on the type of plant species, the type of utilized treatment, and the effective level on studied traits.
