Abstract:

Abstract: The experiment were studied on the change law of soluble protein content, peroxidase and phenylalanine ammonia-lyase of witches broom of jujube branches between Changhong and Yuanhong. The changes of Na2CO3 or NaCl will get an auxin mass fraction of soluble SP content of Y, all could made significant differences on POD. There is a significant difference at 0.01 level on PAL by the change of Na2CO3 . The results showed that peroxidase and phenylalanine ammonia-lyase could be seen as the important physiologic index while resistant variety selecting.
