Abstract
Nanoparticles, atoms or molecules with a size of 1 to 100 nanometers with the ability to drastically change the physical and chemical properties are larger than other materials. Different nanoparticles have been used as fertilizers for plants and the positive effects of different types of nanoparticles have been reported in different plants and there are also reports of negative effects of nanoparticles at high concentrations. Basil (Ocimum basilicum L) is an annual and aromatic herbaceous plant. Since plants need a number of nutrients for their proper growth, the lack of nutrients in the soil is always compensated by the use of various fertilizers. But the necessity of Cobalt for plants has not yet been proven, although it is beneficial for the growth of some plants. In this study, the effect of cobalt-barium nanoparticles in different concentrations (0-100-200-200 ppm) on growth characteristics and some physiological characteristics of basil was investigated. Particle synthesis was performed using sol-gel method. Also, phenol content was measured using Foline-ciocalteu method and flavonoid content by calorimetric aluminum. The results of cobalt-barium nanoparticles treatments in different concentrations showed that nanoparticles at 0.2 ppm increased root and stem fresh weight, root and stem dry weight, germination percentage and phenol and flavonoid content. While increasing the concentration to 0.5 ppm, all traits showed a significant decrease, Therefore, in concluded, the high concentrations of cobalt-barium nanoparticles have negative effects on the plant.
