Abstract: To explore effective methods for inoculating blueberry with endophytic fungiꎬ a pot experiment was conducted
using one ̄year ̄old tissue ̄cultured blueberry seedlings and a strain of endophytic fungus (Talaromyces aculeatus). Five
inoculation methods were designedꎬ as root immersion in fungal suspension(F1)ꎬ mixing fungal suspension with substrate
(F2)ꎬ inoculating with solid fungal blocks (F3)ꎬ root immersion in fungal suspension after root pruning (F4)ꎬ and
irrigation with fungal suspension (F5). Seedlings immersed in sterile water without inoculation served as the control
(CK). Root infection situation after inoculation was statistically analyzedꎬ and determined some indexes that relate to growth
and physiology. The results were as follow: (1) The root infection rates of blueberry were significantly different among the
inoculation methodsꎬ the seedlings inoculated by F2 showed a higher root infection rate than those by other methodsꎬ and
the root infection rate by F5 was the second highest. The root infection rates of treatments F1ꎬ F2ꎬ F3ꎬ F4 and F5 were 2.6ꎬ
3.7ꎬ 3.4ꎬ 3.2 and 3.6 times that of CKꎬ respectively. (2) Except for leaf biomass and root biomassꎬ all other growth
parameters of blueberry seedlings inoculated with endophytic fungi were significantly higher than those of CK. Compared to
the CKꎬ the height incrementꎬ ground diameter incrementꎬ and total biomass of seedlings treated by five inoculation
methods increased by 3.21%-30.47%ꎬ 16.37%-37.43%ꎬ and 9.69%-39.79%ꎬ respectively. The total root lengthꎬ total root
surface areaꎬ total root volume and root tip number increased by 38.63%-118.43%ꎬ 5.08%-94.89%ꎬ 11.97%-65.14%ꎬ and
28.90%-92.44%. (3) The physiological characteristics of blueberry seedlings by different inoculation methods showed
significant differencesꎬ the maximum electron transport rateꎬ minimum saturated light intensityꎬ chlorophyll b contentꎬ and
total chlorophyll content under the F3 were higher than other treatments ꎬ the chlorophyll a content and root activity showed
higher with F2ꎬ while the CK had a higher initial slope than inoculation with endophytic fungi. (4) Based on the
membership function analysisꎬ the comprehensive evaluation result was F3 > F2 > F5 > F4 > F1 > CK. The inoculation
method significantly affects the impact on the growth ̄promoting effect of endophytic fungi. The suitable inoculation methods
are solid fungal blocksꎬ mixing fungal suspension with substrateꎬ and fungal suspension irrigationꎬ which provide important
insights for the efficient cultivation of endophytic blueberry seedlings.
