摘要:
生物防治已经被广泛应用于小麦病害防治中,木霉菌代谢产物生防挖掘是小麦病害防治的热点之一。分离并鉴定出棘孢木霉CBS433.97的代谢产物哈茨二酮,通过对接种赤霉病致病菌禾谷镰刀菌PH-1的小麦施加不同浓度哈茨二酮,研究其对小麦根数、根长和株高的影响,分析哈茨二酮对小麦赤霉病致病菌禾谷镰刀菌PH-1的防效,探究哈茨二酮防治小麦赤霉病的潜力。结果表明,哈茨二酮对小麦根长生长具有促进作用,当哈茨二酮浓度为0.25 mg/L时,促进小麦根长增长20.5%。此外,哈茨二酮具有防治小麦赤霉病的潜能,在小麦赤霉病致病菌禾谷镰刀菌PH-1的胁迫下,哈茨二酮浓度为0.25 mg/L时,多酚氧化酶(PPO)和过氧化物酶(POD)等小麦叶片防御酶活性分别提高60.8%和21.2%,同时抗病相关基因Glu1、Chi1、PR4和PR1.1的表达量分别是CK的2.83、4.62、1165、199.91倍。综上所述,本研究从棘孢木霉CBS433.97代谢物中分离的哈茨二酮能够促进小麦生长并诱导小麦对赤霉病的抗性,具备生物农药开发的潜力,同时可为利用木霉菌代谢产物哈茨二酮防控小麦赤霉病提供理论依据。
