摘要

摘要通过室内和室外试验，测定了小麦内生真菌单孢霉（Simplicillium lamellicola）和绞股蓝（Clonostachys rosea）对禾谷镰刀菌（Fusarium graminearum Schwabe）致病性的诱导能力。内生菌的琼脂接种物在禾谷镰刀菌琼脂接种物施用于相邻叶片之前4天施用。在病原体接种后11天的生长室测试中，在一片叶子上施用片状单孢菌或玫瑰C.rosea处理显著降低了另一片叶子的疾病68%至70%，在接种后9天的室外测试中，与没有生物控制的病原体接种对照相比，显著降低了43%至49%。单孢霉是一种很有前途的生物防治剂，因为它能系统地诱导小麦对禾谷镰刀菌的抗病性。未来需要研究防御反应的作用模式以及这种生物控制剂的正确配方和应用。

Systemically induced resistance against disease of wheat caused by Fusarium graminearum

Abstract The endophytic fungi Simplicillium lamellicola and Clonostachys rosea were assayed for their ability to induce resistance in wheat against disease caused by Fusarium graminearum Schwabe in growth room and outdoor tests. Agar inoculum of the endophytes was applied 4 days before agar inoculum of F. graminearum was applied to adjacent leaves. Simplicillium lamellicola or C. rosea treatments applied on one leaf significantly reduced the disease on another leaf by between 68 and 70% in growth room tests at 11 days post pathogen inoculation and by between 43 and 49% in outdoor tests at 9 days after inoculation compared to pathogen-inoculated controls with no biocontrols. Simplicillium lamellicola is a promising biocontrol agent since it systemically induced disease resistance in wheat against Fusarium graminearum. Future work is needed to investigate the mode of action of the defence responses and the proper formulation and application of this biocontrol agent.

期刊介绍： Canadian Journal of Plant Pathology is an international journal which publishes the results of scientific research and other information relevant to the discipline of plant pathology as review papers, research articles, notes and disease reports. Papers may be submitted in English or French and are subject to peer review. Research articles and notes include original research that contributes to the science of plant pathology or to the practice of plant pathology, including the diagnosis, estimation, prevention, and control of plant diseases. Notes are generally shorter in length and include more concise research results. Disease reports are brief, previously unpublished accounts of diseases occurring on a new host or geographic region. Review papers include mini-reviews, descriptions of emerging technologies, and full reviews on a topic of interest to readers, including symposium papers. These papers will be highlighted in each issue of the journal and require prior discussion with the Editor-in-Chief prior to submission.
