- Abstract
In a microcosm experiment, soils were treated with selected cucumber root exudates components (glucose, succinic acid, p-hydroxybenzoic acid, p-coumaric acid and glutamic acid) at 20 μg C/g soil. The Soil Trichoderma spp. community structure and abundance were estimated by PCR-denaturing gradient gel electrophoresis and quantitative PCR, respectively. Results showed that all exogenously added organic compounds changed the structure and increased the diversity indices of soil Trichoderma spp. community. Among all tested organic compounds, glucose had the strongest, while, p-hydroxybenzoic acid had the weakest influence on soil Trichoderma spp. community structure. p-Hydroxy benzoic acid, glucose, succinic acid and glutamic acid increased the soil Trichoderma spp. community abundance with glucose being the best.
