EnglishWe evaluated mycorrhizal responses of two container-grown ornamental shrubs, Photinia × fraseri and Lantana camara cultivated in soilless substrate with two fertilization regimes and inoculated with two mycorrhizal inocula, a commercial one (Symb) and an experimental one (MicroLab). Fertilization rate, inoculum type and plant genotype differentially affected mycorrhizal colonization, plant growth and mineral nutrition. At high fertility levels a significant reduction of mycorrhizal colonization occurred in both shrubs inoculated with Symb, while MicroLab successfully colonized L. camara roots. In P. fraseri MicroLab increased shoot dry weight at low fertility by 44.3% and 78.6% compared with control and Symb, respectively. In L. camara Symb increased plant height and shoot fresh weight at both fertility levels, compared with MicroLab and Control. Our work shows that host plant/mycorrhizal symbionts compatibility and fertilization may modulate the establishment and performance of mycorrhizal symbioses in container-grown woody ornamentals
