Abstract:
Silicon is the second most common element in soil that has beneficial effects on living and non-living increase stress tolerance in plants. It can lead to increased production and product quality, reduce evaporation of perspiration, increased stimulation of some antioxidant enzymes and decreased sensitivity to some of the fungus. The effects of silicon on seed germination and growth of the bean (Vicia faba L.) were investigated. The seeds of plant were treated by 0 (as control), 1.5 and 3 mM of sodium silicate and silica nanoparticles. There were three repeats for all treatments. The test results showed that seeds treated with sodium silicate concentration of 3 mM significant difference in the percentage of germination than the control no significant difference in the rate of germination of seeds treated compared to control was observed. Hypocotyl length and the flowering of all treated plants were significantly different compared to control. The highest flowering in plants treated silica nanoparticles was observed at a concentration of 1.5 mM. Only plants treated silica nanoparticles with a concentration of 3 mM significant difference in diameter than the control plants. According to the test results can be deduced the effect of silicon nanoparticles in the form of sodium silicate and silica increases the percentage of germination and growth of broad bean.
