Effects of putrescine and ethephon on some oxidative stress enzyme activities and proline content in salt stressed spinach leaves
Özet
The effects of putrescine and ethephon on peroxidase (POD; EC 1.11.1.7), polyphenol oxidase (PPO; EC 1.14.18.1), catalase (CAT; EC 1.11.1.6) activities and proline content in spinach leaves under saline stress were investigated. In control conditions, putrescine increased PPO and CAT activities and proline content, but decreased POD activity. Ethephon increased these three enzyme activities but did not affect proline content. In saline conditions, putrescine increased POD and CAT activities and proline content, while it decreased PPO activity. Ethephon increased both PPO and CAT activities and proline content, but decreased POD activity. Putrescine and ethephon have opposite effects on the enzyme activities and proline accumulation because they acts as antagonists.
