Cinchona officinalis, known locally as cascarilla or cinchona, is a plant species native to SouthAmerica. It was used as a source of quinine to combat malaria in the 17th century. The spe-cies is threatened by various anthropogenic activities. Further, the propagation of the spe-cies depends on seed dispersal and its germination capacity. Therefore, it is necessary toconserve and propagate this species. BecauseC. officinalisseeds have a low germinationcapacity, we determined the effect of arbuscular mycorrhizae (AM) on their germination andgrowth. A randomized design was employed with two treatments, one treated with mycor-rhizae (CM) and another without mycorrhizae (SM). For each treatment, three replicates of100 seeds were used. Germination, growth, and fungal characteristics were evaluated. In ger-mination parameters, the CM treatment showed better performance, but the improvementwas statistically insignificant. However, the application of AM significantly improved seedlingheight (cm), root length (cm), leaf area (cm2), and root number by 53.52, 28.72, 29.73, and61.66%, respectively. Likewise, mycorrhization intensity (%), mycorrhization frequency (%),and extraradical mycelium length (cm) in the CM treatment were 37.13, 3.44, and 174.97%higher compared to the SM treatment, respectively. Therefore, the use of AM fungi provesto be advantageous in the propagation ofC. officinalis, and these results provide a basis forthe largescale and sustainable propagation of this species.
