Abstract

Cucumber seedlings were treated with SA at two leave stage with one real leave expanded and the other real leave unexpanded.The activity of POD,PPO and PAL changed in different level after treatment.The activity of POD changed obviously at 24 h after treatment,and increased steadily,till 144 h after treatment it increased 193% as compared with control.However the changes of PPO activity were less than that of POD.The activity of PPO increased by 61.7% 144 h after treatment.The PAL activity reached a little peak 72 h after treatment and then declined,another peak appeared in 120 h after treatment.Inoculation with Pseudoperonospora cubensis 4 d after treatment,the results show that the disease index of the first and the second real leaves were reduced by 8.9% and 22.1% respectively.
