Abstract
The sterile line 8Aand maintainer line 8Bof pepper were chosen as experimental material, the changes of the content of proline and soluble protein,and activity of peroxidase(POD)and catalase(CAT)were determined at different development stage.The results showed that the content of proline and soluble protein in sterile line 8Awas significantly lower than that of in maintainer line 8B.The activity of POD in sterile line 8Awas significantly higher than that of in maintainer line 8B;however,the activity of CAT in sterile line 8A was significantly lower than that of in maintainer line 8B.The activity of POD in sterile line 8Akept rising,while in maintainer line 8Bdecreased.The activity of CAT in sterile line 8Akept decreasing,while in maintainer line 8Brose.It is suggested that the content of proline and soluble protein, and the activity of POD and CAT may be related with the occurrence of male sterile flax.
