主 题：Arbuscular mycorrhizal fungi rubber tree species diversity influence factors plantation age
摘 要：Hevea brasiliensis is one of the important economic trees with a great economic value for natural rubber *** between roots of *** and arbuscular mycorrhizal fungi(AMF)is widely recognized,and can provide a range of benefits for both of *** Island harbors is one of the largest plantations of *** in China,whereas the information regarding the diversity of AMF in the rhizosphere of *** on this island is *** 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 *** RY7-33-97 were *** 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 ***,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 ***(Frequency,F=100%)and Acaulospora(F=100%)were the predominant genera,and ***(F=63.9%)and ***(F=63.9%)were the predominant *** 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 ***,SD,SR,and H were also correlated with *** plantation age,and an increasing trend was observed up to 40 *** results suggest that the AMF community was
