Abstract:
The a im of th is study w as to investig ate the effects o f d ifferent concentrations of selen ium in m edium on grow th and antiox idative system in protocorm- like bod ies o fD. officinale. The results showed tha t low concentration of se len ium ( ≤ 0.2 mg /L) could prom ote the grow th o f pro to co rm- like bod ies, how ever, h igh concentra tion of se lenium ( 0. 2 mg / L) showed the oppos ite e ffect. Furtherm ore, them ost appropr ia te selen ium concentration for the g row th o f pro toco rm- like bod ies was 0.05m g /L. Low concentration o f se lenium could sign ificantly increase the activations o f SOD, CAT and GSH - PX, however, inh ibite the activation of POD, the rate o f O-.2 gene ration and the leve l o fMDA. Oppos ite effects were seen a t high concentra tion o f selen ium. Therefore, itw as ind ica ted that proper se len ium concentra tion cou ld increase the y ield and antiox idative activ ity o f protocorm- like bodies o fD. off icinale.
