| 摘 要： | 用碱解离-酸性品红染色法对10株盆栽滑桃木的根样进行了调查研究,结果表明,10个根样中均有丛枝菌根真菌侵染,且侵染比率较高,平均侵染率75%以上,达到深度侵染.用湿筛-沉淀法对盆栽植物根际土壤分别进行处理,结果表明,根际土壤中平均每100g土中有孢子270个,无梗囊霉属(Acaulospora)和球囊霉属(Glomus)为优势属,其中,刺状无梗囊霉(Acaulospora spinosa)、细凹无梗囊霉(Acaulospora scrobiculata)和单孢球囊霉(Glomus monosporum)是常见种.

| Abstract: | 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. |
