Hevea brasiliensis is one of the important economic trees with a great economic value for natural rubber production. Symbiosis between roots of H. brasiliensis and arbuscular mycorrhizal fungi (AMF) is widely recognized, and can provide a range of benefits for both of them. Hainan Island harbors is one of the largest plantations of H. brasiliensis in China, whereas the information regarding the diversity of AMF in the rhizosphere of H. brasiliensis on this island is scarce. The diversity of AMF species in the rhizosphere of rubber tree plantations in Hainan was investigated in this study. A total of 72 soil samples from the rhizosphere of H. brasiliensis RY7-33-97 were collected. These included 48 samples from plantations in 11 cities or counties that had been planted for 15–25 years, and 24 samples from a demonstrating plantation site of the China National Rubber Tree Germplasm Repository representing plantations with tree plantation ages from one to 40 year-old. Collectively, a total of 68 morphotypes of AMF, belonging to the genera of Archaeospora (1), Glomus (43), Acaulospora (18), Entrophospora (3), Scutellospora (2), and Gigaspora (1) were isolated and identified, as per morphological characteristics of spores presented in the collected soil samples. Glomus (Frequency, F = 100%) and Acaulospora (F = 100%) were the predominant genera, and A. mellea (F = 63.9%) and A. scrobiculata (F = 63.9%) were the predominant species. AMF species differed significantly among collected sites in spore density (SD, 290.7–2,186.7 spores per 100 g dry soil), species richness (SR, 4.3–12.3), and Shannon-Weiner index of diversity (H, 1.24–2.24). SD was negatively correlated with available phosphorus level in the soil; SR was positively correlated with soil total phosphorus content; and H was positively correlated with levels of soil organic matter and total phosphorus. Similarly, SD, SR, and H were also correlated with H. brasiliensis plantation age, and an increasing trend was observed up to 40 years. These results suggest that the AMF community was complex and ubiquitous in the island plantation ecosystems of H. brasiliensis, with high species abundance and diversity. Soil factors and plantation age dramatically affected AMF diversity at species level.
