The universally positive effects of arbuscular mycorrhiza on plants suggest that fully developed mycorrhizal hyphae could potentially induce faster germination in seeds. This study presents data indicating that the inoculation of full grown hyphae in seeds of Lolium perenne inhibits speed of germination, independent of level of available soil nutrients. Daily measurements of seedling height between in- fected and non-infected plants at different starter fertilization rates in a sand profile showed that abuscular mycor- hiza influenced seeds emerged later at higher germination success rates. Measurements in shoot biomass height and weight conversely showed that, once emerged, AM plants grew at a faster rate than NM plants. This supports the indication that inoculation of developed AM fungal mycelium, instead of AM spores, cannot further expedite rates of seedling emergence, but could possibly improve rates of seed germination.
