Abstract: (7 Views)
Black seed (Nigella sativa L.) is one of the best sources of natural antioxidants with compounds such as alkaloids, flavonoids and tannin. Black seed plant seeds are used in traditional medicine of many countries to prevent and treat disorders and diseases. Since the production of medicinal plants can be affected by environmental factors such as water limitation, an experiment was conducted to investigate the effect of folic acid and titanium dioxide nanoparticles under drought stress conditions on phytochemical characteristics including the percentage of essential oil, oil content, leaf protein, glucose, fructose, sucrose, proline, superoxide dismutase, catalase and peroxidase of black seed medicinal plants. It was carried out during two crop years of 2018 and 2019 in the research farm of Shahrood University of Technology. This experiment was conducted as a split factorial in the form of a randomized complete block design with three treatments in three replications. The main plot consisted of three levels of irrigation (50, 75, and 100% of available water) and sub-plots included folic acid (0, 250 and 500 mg/l) and titanium dioxide nanoparticles (0, 1, and 2 mg/l). The results showed that the effect of irrigation treatments, folic acid and titanium dioxide nanoparticles on the content of catalase, superoxide dismutase, glucose and peroxidase, the effect of irrigation treatments on proline content and the effect of irrigation treatments and folic acid on the content of sucrose and fructose were significant. In the treatment of 50% drought stress, the amount of catalase (4.84 Unit/mg pro), peroxidase (61.2 Unit/mg pro), superoxide dismutase (61.3 Unit/mg pro), proline (16.85 mg/gr), glucose (52.61 mg/gr), fructose (31.08 mg/gr) and sucrose (9.80 mg/gr) went up. In the treatment of 50% drought stress with 500 mg per liter of folic acid and 2 mg per liter of titanium dioxide nanoparticles, the highest amounts of glucose (58.26 mg/gr), fructose (36.09 mg/gr) and sucrose (12.11 mg/gr) were obtained. Also, the results showed that drought stress led to a decrease in essential oil, oil percentage and leaf protein. The highest percentage of essential oil, percentage of leaf oil, and protein was observed with the use of 500 mg/L of folic acid and 2 mg/l of titanium dioxide nanoparticles with 100% water. Overall, based on the results of this experiment, it is recommended to use folic acid fertilizer (500 mg/l) and titanium dioxide nanoparticles (2 mg/l) in order to reduce the effects of drought stress on black cumin.
