Eight AMF inocula were tested, including monocultures of Claroideoglomus claroideum, Funneliformis caledonium, and F. mosseae plus two isolates of Rhizophagus irregularis, all applied as 4% (v) of the substrate, or their mixture in 1%, 4% and 8% (v) doses. Their infectivity was monitored for 56 weeks at 8-week intervals as measured by mycorrhizal root colonization of bioassay plants. In general, infectivity significantly decreased with time, but in three regimes including periods of cold (5 °C, shade and sunlight), cold stratification probably broke spore dormancy and led to temporal stimulation of AMF infectivity. Except for storage at 5 °C, where a wider AMF spectrum maintained sufficient long-term viability, infectivity became very low after 1 year. Temperature fluctuations in direct sunlight were less negative than expected, whereas infectivity decline was surprisingly strong also in mild storage conditions (20 °C). Higher inoculum dose lengthened AMF infectivity. R. irregularis isolates were found most resistant among the tested AMF. We ascribe the general decline of infectivity to unfavorable properties inherent to peat.
