Arbuscular mycorrhizas of Trewia nudiflora

The arbuscular mycorrrhzal status of 10 plant roots of Trewia nudiflora were investigated by means of acid fuchsin stain after the roots were lysised in alkaline solution.The results showed that intensitive infection(above 75%)was observed in all of the 10 plant root samples.five-hundred and thirty nine arbuscular mycorrhizal fungal spores were obtained from the rhzosphere soils of the 10 plants by wet-sieving,and the results showed that the average spore density is 270 per 100 g soil.Acaulospora,Glomus were the Predominant genera,and Acaulospora spinosa,Acaulospora scrobiculata and Glomus monosporum were the common species.
