用FPLC方法分析了抗小麦赤霉病程度不同的8个小麦品种种子的水溶性组分。结果表明,所有小麦品种都有1个保留时间为9min的吸收峰(P9),且抗病品种中该吸收峰的高度明显高于感病品种。种子水溶液经过氧化氢温育处理后,P9明显升高,表明有大量的P9生成。因此,推测P9可能是1种与小麦抗赤霉病性相关的生化成分,在小麦抗赤霉病的过程中起作用。
The water soluble components of eight wheat cultivars with different degrees of resistance to FHB were analyzed by FPLC method. The results showed that all the wheat cultivars had one peak (P9) with a retention time of 9 min, and the height of the absorption peak in resistant cultivars was significantly higher than that in susceptible cultivars. Seed water solution after hydrogen peroxide incubation, P9 was significantly increased, indicating that a large number of P9 generation. Therefore, it is speculated that P9 may be a biochemical component related to the resistance to scab in wheat and plays a role in the process of scab resistance in wheat.
