- Abstract:
- For the purpose of discussing the mechanism of resistance to aphid of different soybean materials,the dynamics of MDA content and the activities of protective enzymes in the leaves of soybean materials with different resistance to Aphis glycines Matsumura were preliminarily studied.The results showed that MDA content and the SOD，POD，PPO and PAL activities in soybean materials with different aphid resistance were all increased in 24 h after inoculation of the Aphis glycines Matsumura.Soybean with higher aphid resistance showed lower increment of MDA content and higher increment of SOD，POD，PPO and PAL activity.Therefore，under the stress of aphid，the variation degree of SOD，POD，PPO and PAL activity were closely related with the resistant mechanism of soybean to aphid.
