Abstract 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 endophyt⁃
ic 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%，respec⁃
tively，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 sta⁃
bility（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.
