The 8-year-old field-cultivated Lane Late navel orange was inoculated with three arbuscular mycorrhizal fungi （Acaulospora scrobiculata，Diversispora spurca，and D. versiformis） and an endophytic fungus （Piriformospora indica） and the fruit quality and root/rhizosphere soil properties of lane late navel orange were analyzed to study the effects of the inoculation with arbuscular mycorrhizal fungi and endophytic fungi on the fruit quality and root/rhizosphere soil properties of lane late navel orange.The results showed that the root fungal colonization rate of inocualted trees was from 23.3% to 27.4%，which was significantly increased by 17%-38% compared with that of uninoculated trees.Inoculation of symbiotic fungi significantly increased fruit set，flesh weight and fruit weight per fruit by 65%-152%，20%-36%，and 13%-34%，respectively，along with reduced fruit hardness by 22%-39%.These symbiotic fungi also increased fruit coloration value，polar and equatorial diameter，the content of glucose，fructose and sucrose to varying degrees，but it was different due to fungal species.In addition，the symbiotic fungi significantly increased soil aggregate stability （MWD），the content of organic carbon （SOC），Olsen-phosphorus，and glomalin-related soil protein （GRSP） by 23%-31%，4%-26%，53%-147%，and 10%-138%，respectively，but inhibited the content of available potassium.The results of correlation analysis showed that root fungal colonization was significantly or significantly positively correlated with fruit sugar components，soluble solids，easy-to-extract GRSP，MWD，SOC and available phosphorus.It is indicated that D. spurca has the most prominent effect on fruit appearance quality，sugar composition，soil structure and fertility.
