Abstract:
Festuca arundinacea cv.Barlexas seeds were taken as test material,the effects of Zn2+ stress on its seed and physiological and biochemical of seedling that were cultured in different concentrations (12.5,25.0,50.0,100.0 mg?L-1) of ZnSO4 were discussed.The results showed that Zn2+ stress exhibited high inhibitory effects on Festuca arundinacea cv.Barlexas.The plant seeds germination rate was decreased with the Zn2+ concentration increased,but there was no obvious change.With the increasing of Zn2+ concentration,the root length,the biomass of seedlings and contents of chlorophyll and carotenoid decreased obviously.The results of physiological and biochemical characteristics indicated that the activities of SOD and POD tended to firstly decrease then increase with the increasing of Zn2+ concentration;the content of MDA tended to increase;the content of proline tended to firstly increase then decrease with the increasing of Zn2+ concentration.The root vigor showed to decrease gradually with the increasing of Zn2+ concentration.
