Abstract
Effects of arbuscular mycorrhizal fungus (AMF) Glomus mosseae on plant growth, soil microbial populations and enzymes activities of soils were studied in red clover ( Trifolium pratense L.) grown in pots at different cultivated densities. Seeds of red clover were sown with 50 g inoculums of G. mosseae per pot. After a week, the plants were thinned to 20, 30, 40, 50 and 60 seedlings per pot. Three months after treatment, AMF inoculation significantly stimulated plant growth. Quantities of vesicles and spores, arbuscules and hyphae were the highest when 30 and 50 seedlings were grown per pot, respectively. However, no root was infected in control plants. In all the soil sites, the numbers of fungi and bacteria were followed in the order: root > root surface > rhizospheric. It was indicated that arbuscular mycorrhizal fungus decreased the numbers of fungi and bacteria but improved growth of actinomycetes. Compared to control plants, AMF stimulated activities of phosphatase and urease but decreased invertase.
