Since 80s,the infected area by head blight of wheat (Fusarium gramin-earum,Schw,) has been developing and the degree of development increasing gradually year after year,because of the change of cuhivating system and the availabe irrigation condition, which formed a farmland- ecologic environmet there was adventageous to outbreack of the disease.

宁夏引黄灌区自80年代中期以来，由于耕作制度的改变，又有灌溉条件，构成了有利于小麦赤霉病发生和流行的农田生态环境，发病面积逐年扩大，发病程度不断加重。

After non-inoculated samples were treated with H2O2, peaks of protein had the trend of left-moving in resistant varieties, but trend of right-moving in susceptible varieties. So, when H2O2 existed, enchancement of POD activity impelled low-weight substance to polymerize high-weight protein in resistant varieties, but no difference in susceptible varieties.Samples from callus of five wheat varieties with varying degrees of resistance against wheat head blight were examined by FPLC.

对照样品在过氧化氢水浴(35℃)处理后，抗性品种的蛋白峰有&左移&现象，P_0峰有所提高，表现与赤霉病菌接种处理一致的趋势，因而，在H_2O_2存在的前提下，抗性品种中POD活力的提高促使小分子量物质聚合成大分子量的蛋白，而在感性品种中没有这些变化的出现。
