摘要
[目的]研究球毛壳DN35对植物生长的影响及其生防效果,为该菌的推广应用提供依据。[方法]以植物内生真菌球毛壳(Chaetomium globosum)ND35为供试菌株,在温室和大田条件下测定其对植物生长的影响及其对5种植物病害的防治效果。[结果]ND35对杨树侧根和胸径生长有一定的促进作用。接种ND35能诱导杨树对腐烂病菌和叶锈病菌产生抗性;也能诱导番茄和菜豆对灰霉病菌产生系统抗病性;还可有效防治菜豆立枯病。[结论]内生真菌球毛壳ND35引起的诱导系统抗病性在植物病害的生物防治中有重要作用。
[ Objective ] The aim was to study effect of Chaetomium globosum ND35 on plant growth and preliminary study of its biocontrol efficacy, and provide basis for popularization and application of this strain. [ Method ] With endophytic fungus C. globosum ND35 as a tested strain, effect of C. globosum ND35 on plant growth and its biocontrol on five plant diseases were investigated in the greenhouse and field. [ Resuit] The results showed that ND35 promoted growth of lateral root and diameter of breast height of poplar. ND35 can induce poplar to resist poplar canker caused by Valsa sordida and poplar leaf rust caused by Melampsora puplicola. ND35 was also able to induce tomato and bean to resist Botrytis cinera. Biocontrul of bean damping-off by ND35 was effective as well. [ Conclusion ] Induced systemic resistance by endophytic C. globosum ND35 plays an important role in biocontrul of plant diseases.
