| Abstract: | A strain of Trichoderma spp. LT19 was isolated from soil in Shandong Province, which showed a broad inhibition spectrum against various soil -borne plant phytopathogenic fungi. It also exhibited some plant growth - promoting attributes such as phosphate solubilization, indol - 3 - acetic （IAA） productivi- ty, 1 - aminocyclopropane - 1 - carboxylate The pot experiments showed that inoculation （ACC） deaminase activity and siderophore （S） synthesis ability. with the strain could increase the biomass of cucumber Based on its morphology and ITS gene sequences, the strain LT19 was identified seedlings as Trichoderma asperellum. |
