Abstract

A study on soil fungal diversity of Solanum rostratum-invaded and non-invaded areas in Liaoning province.

Abstract

Soil fungal diversity and numbers were analysed in Solanum rostratum-invaded and non-invaded areas in Liaoning province from 2008 to 2009. One hundred and fifty soil samples were collected and cultured with the soil plate method. All the species were identified and divided into 30 genera, of which Penicillium, Aspergillus, Trichoderma, Mucor, Rhizopus and Fusarium were the dominant groups of the S. rostratum-invaded areas. According to the Jaccard index of similarity theory, the similarity level of the soil fungal communities was medium between the invaded and non-invaded areas. Cj values were between 0.50 and 0.75. Soil fungal diversity was not significantly different between invaded and non-invaded areas. From the soil fungal flora, it is probable that S. rostratum spread to non-invaded areas.
