Abstract
Abstract In order to explore the influence of selenium (Se) on the development of rice, various levels of sodium selenite (Na2SeO3) were treated on rice in the present study. The results showed that under the condition of 13-104 μmol/L Na2SeO3 treatment in comparison with the control group (0 μmol/L Na2SeO3 treatment), the plant height of rice in the experimental group decreased by 8.72%-47.36%; fresh weight and dry weight decreased by 67.5%-88.35% and 64.52%-87.82%, respectively. In addition, high selenium treatment also significantly increased the antioxidant activity of rice, and the enzyme activities of CAT, SOD and POD were up-regulated by 16.07%-48.21%, 20.94%-73.00%, and 34.65%-53.65%, respectively. Rice might regulate the stress response system in vivo through those reactions, so as to resist the adverse environmental stress. The findings of this research could establish theoretical basis for the cultivation of Se-rich rice.
