| Abstract: | Activities of activated oxygen scavenger enzyme and contents of malondialdehyde (MDA) of flower buds and anthers in the genic cytoplasm double male sterile (GCDMS) line DCDA 2 ( Brassica napus L.) were studied. Compared with cytoplasm male sterile (CMS) line L17A and genic male sterile (GMS) line L18A (the parents of GCDMS), GCDA 2BA plants of GCDA 2 were similar to CMS, expressed higher activities of superoxide dismutase (SOD) and catalase (CAT), higher contents of malondialdehyde (MDA). GCDA 2HA plants of GCDA 2 were similar to GMS; GMS had lower MDA and higher SOD, POD and CAT in buds, and higher MDA, SOD, POD and CAT in anthers; The results also showed CMS and GMS were different types in activated oxygen metabolism mechanics. |
