Effect of insect pest on activated oxygen metabolism in lanceolate leaves of Populus euphratica under different water condition

Abstract

Abstract: This paper studied the effect of insect pest on the activities of protective enzymes SOD and CAT and the contents of H₂O₂ and H₂O₂ in lanceolate leaves of Populus euphratica under different soil water conditions.The results showed that soil water deficiency did not increase SOD and CAT activities and H₂O₂ and H₂O₂ contents in lanceolate leaves,but under this condition,insect pest increased them.When soil water was abundance,insect pest couldn't increase the activities of SOD and CAT and the contents of H₂O₂ and H₂O₂ in lanceolate leaves.It's concluded that insect pest had an important role in death of Populus euphratica under soil water deficiency.

Key words: Water stress, Insect pest, Active oxygen species, Antioxidant enzyme
