叶枯唑防治水稻白叶枯病的作用方式研究
Action Mode of Bismerthiazol against Rice Leaf Blight
-
摘要: 叶枯唑具有诱导受体植物水稻产生抗病性的作用 ,能使水稻体内脂质过氧化程度加强 ,刺激水稻体内产生 O-2 ,阻止白叶枯病菌侵入。O-2 清除剂 (甘露醇、抗坏血酸 )处理水稻能显著降低叶枯唑的保护作用。叶枯唑也能直接作用于水稻白叶枯病菌 ,抑制菌体生长 ,表现出治疗作用。Abstract: Bismerthiazol bactericide showed its protective and curative efficacy on controlling rice leaf blight caused by Xanthomonas oryzae pv. oryzae . The fact that bismerthiazol has effect on induction of rice resistance to X . oryzae has been proved. Lipid peroxidation and superoxide anion have increased in the leaves that were treated with the bactericide. O - 2 scavengers, mannotol and ascorbic acid have decreased obviously the protective efficacy of bismerthiazol. Bismerthiazol also has direct effect on inhibiting growth of the bacteria and showed its curative efficacy.
