摘要

木霉因其对多种植物病害的生物防治作用而闻名。一种特殊的木霉分离株具有抑制苹果黑斑病病菌的生长的能力。本研究采用显微镜观察法(40X)研究了atroviride与马里Alternaria mali菌丝体的相互作用。从一棵苹果树的层球中分离到木霉。引物(ITS 1和ITS 4)鉴定该生物制剂为阿托维绿木霉分离物TV3。序列提交给NCBI，登记号为0L694002。严重的分枝寄生以盘绕和牢固附着的形式出现，偶有附着胞样结构的产生。生物防治剂大量繁殖，形成密集的菌丝体，具有一些附着胞样结构，可穿透病原体菌丝体。

MICROSCOPIC INTERACTION BETWEEN TRICHODERMA ATROVIRIDE STRAIN TV3 AND PATHOGEN ALTERNARIA MALI

Trichoderma spp. is well-known for their biocontrol efficacy against a variety of plant diseases. A particular isolate of Trichoderma spp. has the capacity to limit the growth of Alternaria mali , which causes Alternaria leaf spot of apple. In this study, the interaction between T. atroviride and mycelia of Alternaria mali was studied (microscopy 40X). Trichoderma spp. was isolated from the phyllosphere of an apple tree. Primers (ITS 1 and ITS 4) identified this putative bioagent as Trichoderma atroviride isolate TV3. Sequence were submitted to the NCBI and assigned the accession number 0L694002. A severe mycoparasitism was noticed in the form of coiling and firmly attaching, with the occasional production of appressoria-like structures. The biocontrol agent multiplied abundantly, forming a dense mycelium with some appressorium like structures that penetrated the mycelium of pathogen.
