| 摘 要： | 对海南霸王岭热带雨林的12科16种常见植物的丛枝菌根状况进行了调查,用碱解离-酸性品红染色法进行了真菌鉴定。结果表明,13种植物形成典型的丛枝菌根,占所调查植物的81%;3种植物没有形成丛枝菌根,占所调查植物的19%。用湿筛沉淀法从这些植物根际土壤中共分离鉴定出了3属11种丛枝菌根真菌(AMF),即无梗囊霉属(Acaulos-pora)3种,球囊霉属(Glomus)7种,巨孢囊霉属(Gigaspora)1种;其中,球囊霉属是样地的优势属。在AMF中,孔窝无梗囊霉(A.foveata)分离频率最高,在14种植物的根际土中都有发现;此外,大果球囊霉(G.macrocarpum)的相对多度最大,为59%,具有最强的产孢能力。同时,在11种植物的根中发现了深色有隔内生真菌(DSE),占调查植物的69%;其中,11种植物同时被DSE和AMF感染。

| Abstract: | An investigation was made on the arbuscular mycorrhiza (AM) and dark septate endophytes (DSE) associated with 16 common plant species belonging to 12 families in a tropical rain forest in Bawangling of Hainan Island,China. The fungi were identified by alkaline lysising and acid fuchsin staining. Among the surveyed plant species,13 of them (occupying 81% of the total) were typically colonized by arbuscular mycorrhizal fungi (AMF),while 3 species (about 19%) did not form AM. Eleven AMF species in 3 genera wer... |
