The monodominance of Acuri in Pantanal formations: allelochemical effects of its leaves and the presence of Acurizais
Abstract The presence of monodominant vegetative formations almost exclusively composed of Acuri palm trees (Attalea phalerata) stands out in some regions of the Pantanal Sul-Mato-Grossense. These formations are generally associated with anthropic, edaphic and/or hydrological factors. However, littl...

| description | Abstract The presence of monodominant vegetative formations almost exclusively composed of Acuri palm trees (Attalea phalerata) stands out in some regions of the Pantanal Sul-Mato-Grossense. These formations are generally associated with anthropic, edaphic and/or hydrological factors. However, little is known about the effect of allelopathy on the formation and maintenance of these areas. Herein, we investigated the chemical composition of A. phalerata aqueous leaf extract and the potential allelopathic effects on germination and growth of target L. sativa, L. esculentum and S. obtusifolia species. Thus, extracts at concentrations of 0, 2.5, 5, 10, 15, and 20% were used for germination and growth bioassays with a completely randomised design in a germination chamber and greenhouse. The results showed that the A. phalerata extracts negatively affected the germination speed index and mean germination time of the target species and positively affected seedling length under controlled conditions and were also stimulated in the greenhouse. Thus, the formation of Acurizals can be related to the presence of secondary metabolites in the leaves, in addition to other environmental factors. |
