Abstract
In this study,effects of 0 μmol /L,0. 5 μmol /L,1. 0 μmol /L,1. 5 μmol /L and 2. 0 μmol /L Na2SeO3 on physiological characteristics of rice seed germination under PEG stress were explored. The results showed that 0. 5 μmol /L and 1. 0 μmol /L Na2SeO3treatment significantly improved seed germination rate compared with the control. α-Amylase activity,soluble sugar and soluble protein content in germinating seeds were increased,but free amino acid content was reduced. Also,radical root activity and root length were increased.In contrast,2. 0 μmol /L Na2SeO3 exerted opposite effects on seed germination. Obviously,low concentrations of Na2SeO3 treatment can alleviate PEG stress,but high concentrations aggravated the adverse effects of PEG stress on seed germination.
