- Abstract
Selenium with antioxidant properties has positive effects on growth and development of biological activities of many plants, although its excessive levels in soil causes physiological problems. This study was conducted to investigate the effect of selenium (bulk) and nano-selenium on some physiological and biochemical properties of Vasha, in a completely randomized experiment. Selenium was applied in nutrient solution as sodium selenate (0, 2.5, 5, and 10 mg L
–1 concentrations) and as nanoselenium (0, 2.5, 5, 10, and 20 mg L–1 concentrations). Results showed that application of both bulk and nano-Se treatments significantly increased plant growth parameters, i.e. root and shoot lengths and fresh and dry weights as well as the content of photosynthetic pigments, total flavonoids, total phenols, anthocyanins, and carbohydrate contents under 2.5 mg L–1 and 10 mg L–1 of selenium and nano-selenium, respectively. In addition, these concentrations were associated with a significant increase in plant antioxidant activity. Moreover, all treatments reduced malondialdehyde contents of the plants under study. The maximum increase in chlorophyll a was observed in the treatment with10 mg L-1 nano-Se, which decreased with increasing selenium concentration compared to the control treatment. The results also showed that the positive effects of selenium on the growth and increasing phenolic compounds depend on the type and concentration of selenium application.
