“…Andreazza et al . [ 52 ] obtained similar results in their studies, in which, even though a fungal mantle did develop, no difference was detected between the control plants and the in vitro fEcM ( Suilus sp.) inoculated canafistula plants in terms of height, root system fresh mass, and fresh and dry shoot masses.…”

“…Researches about the presence of ectomycorrhizae in different ecosystems native of Brazil supports this idea. Examples of this include reports of ectomycorrhizal symbiosis formation in native Myrtaceae to that biome, such as in trees of the Campomanesia and Eugenia genera [ 51 ], and studies that show an in vitro association between fEcMs and the grapia ( Apuleia leiocarpa ) and canafistula ( Peltophorum dubium ), species native to Southern Brazil's forests [ 52 ]. In addition, a large study carried out on Amazonian Lowland White-sand Forests in Brazil and French Guyana found 62 morphospecies of ectomycorrhizae associated with native trees in these areas [ 4 ].…”

Like many other species of trees native to the Brazilian Mata Atlântica (Atlantic Forest), the Myrtaceae, such as the Red Araza (Psidium cattleianum Sabine), are widely cited as arbuscular mycorrhizal formers. Nevertheless, recent studies show evidence that Myrtaceae from different tropical, subtropical and neotropical ecosystems can also prompt the formation of ectomycorrhizae, indicating that this species' ectomycorrhizal status should be further explored. Because of this, this research effort studied the in vitro interaction between the Red Araza and two ectomycorrhizal fungi isolates, belonging to the Pisolithus microcarpus (D17) and Scleroderma citrinum (UFSC-Sc133) species. An analysis was performed to determine the formation of ectomycorrhizal structures, or lack thereof, and the developmental differences between the in vitro mycorrhized and non-mycorrhized plants. The analysis proved that indeed an ectomycorrhizal association was developed between the Red Araza, and the D17 and UFSC-Sc133 isolates, a fact never before registered in the existing literature. After an in vitro period of 110 days, it was confirmed that the D17 and UFSC-Sc133 isolates formed mycorrhizal colonization of 91.6% and 15.7%, respectively. Furthermore, both isolates also promoted root thickening, and the formation of a fungal mantle and a Hartig net. However, when compared to the Control plants, the fungal isolates did not contribute to an increase in the development of the subject plants, possibly due to the specific experimental conditions used, such as a high humidity environment and high availability of nutrients in the symbiotic substrate.
