A series of two greenhouse experiments aimed on this question. In the first experiment, we tested the effect of inoculation with AMF, applied as a commercial inoculum, on various biometric parameters including the flowering of eight ornamental plant species. Capsicum annuum, Dimorphoteca sinuata, Gazania splendens, Impatiens hawkerii, Pelargonium peltatum, Pelargonium zonale, Sanvitalia procumbens and Verbena x hybrida were planted in pots with a peat-based substrate. AMF were naturally absent in this substrate. The plant species differed in their mycorrhizal growth response (MGR) evaluated as the effect of inoculation on shoot biomass. The MGR was positively correlated with the level of root colonization, which ranged from 17% to 68% depending on the plant species. Inoculation with AMF also significantly increased other growth parameters important for ornamental plants, namely the number of flowers (S. procumbens, Verbena x hybrida), flower size (I. hawkerii), shoot dry weight (P. peltatum, P. zonale and S. procumbens), root dry weight (G. splendens, P. peltatum and S. procumbens), the number of leaves (C. annuum, G. splendens, P. peltatum and P. zonale), plant length (C. annuum, P. zonale and S. procumbens), the number of branches (P. zonale and S. procumbens) and the total length of branches (S. procumbens). In the second experiment, P. zonale was used as a model plant grown under two watering regimes.
