Effect of combined treatment of 60Coy-ray and EMS on antioxidase activity and ODAP content in Lathyrus sativus

Abstract

Abstract: Lathyrus sativus seeds were treated with ⁶⁰Coγ-ray and EMS(ethyl methane sulfonate), and their emergence rate and SOD,POD and CAT activities were determined. The result indicated that the treatment decreased the emergence rate. The activities of SOD and POD were changed in accordance with the increase of irradiation dose and EMS concentration, while that of CAT had no obvious change. After treatment, the ODAP content in Lathyrus sativus decreased. Amutant was developed, with toxin content of 0.1%, compared to 0.2% in control.

Key words: Lathyrus sativus, EMS, ⁶⁰Coy-ray(unit.Krad), ODAP(β-N-Oxalyl-α,β-diamino propionic acid)
