摘要：
Enhanced somatic embryogenesis and plant regeneration have been obtained using young leaf bases of naked oat (Avena nuda) as explants by including salicylic acid (SA) and carrot embryogenic callus extracts (CECE) in media. A 5- and 4-fold improvement was achieved in somatic embryogenesis and plant regeneration on the corresponding media supplemented with 0.5 mM SA and CECE as compared to control, respectively. Some physiological and biochemical changes were assayed in both embryogenic callus (EC) and non-embryogenic callus (NEC). The results indicated that superoxide dismutase activity was stimulated and catalases and ascorbate peroxidase activities were inhibited, while the 02 (superoxide anion) content was reduced and the hydrogen peroxide level was promoted in EC compared with NEC. Reduced malondialdehyde content and relative electrolyte leakage were also detected in EC.
