Abstract

To obtain both optimal germination rate and organic- selenium content,germination conditions such as sodium- selenite concentration in soaking solution,cultivation time and cultivation temperature were investigated by Box- Behnken central composite design( CCD) combined with response surface methodology.The results showed that the optimal parameters were as follows: sodium selenite solution 68 mg / L,cultivation temperature 30 ℃,cultivation time 31 h. Under these conditions,germination rate reached 81.9% and the contents of Se reached0.870 mg / kg.
