Survey of fungi associated with grass roots in virgin soils on the Springbok Flats


, : Survey of fungi associated with grass roots in virgin soils on the Springbok Flats. South African Journal of Botany 60(1): 67-72

Root- and soil-inhabiting fungi were isolated from various grass species in virgin soil at nine localities on the Springbok Flats with the initial purpose of detecting natural hosts of the crater disease pathogen of wheat, viz. Rhizoctonia solani Kuhn. Although Rhizoctonia spp. were found at four localities, all isolates were binucleate, and therefore not R. solani. Nevertheless, the survey provided qualitative and quantitative information on the indigenous soilborne mycoflora of the region. Periconia macrospinosa Levebvre and A.G. Johns-on and Fusarium nygamai Burgess and Trimboli were the dominant colonizers of grass roots. Other fungi which occurred relatively commonly in roots included Fusarium oxysporum Schlecht. emend. Snyd. and Hans., F. solani (Mart.) Appel and Wollenw. emend. Snyd and Hans., F. equiseti (Corda) Sacc., F. moniliforme Sheldon, Phialophora spp., Stachybotrys elegans (Pidopl.) W. Gams, Gliocladium catenulatum Gilm. and Abbott, Acremonium strictum W. Gams, and Phoma sorghina (Sacc.) Boerema, Dorenbosch and van Kesteren.
