SUMMARY:

Amazonian indigenous peoples use plant species for different purposes, such as medicinal, food, ritualistic and material, among others. In view of this, ethnobotanical investigations have been a primary approach and recognized by scholars worldwide as a strategy for selecting useful plants. This work aims to investigate and record traditional knowledge about the uses, preparation techniques and management of akrô, the name given to climbing plants in the Kriny village, Kayapó Indigenous Land, located approximately 80 kilometers from the municipality of Bannach, in the mesoregion of Southeast Pará. The first chapter aimed to understand and document the diversity of uses and the cultural importance of akrô in the daily life of the Mebêngôkre-Kayapó. The research was initially conducted with two collaborators, using the guided tour technique to collect information and botanical samples. Subsequently, the checklist-interview was applied to ten new collaborators. Fifty-two species belonging to 42 genera and 23 families were identified. Among these, the most representative was Bignoniaceae (10 spp.). There was a predominance of woody vines (51.92%). The fickle mechanism is present in 65% of the species recorded. Akro species are found in six environments; half of them are both spontaneous and cultivated. Among the six categories of use, the most cited was medicinal (74.68%). The second chapter aimed to document and understand the traditional knowledge about the use of climbing plants as medicine for the Mebêngôkre-Kayapó. The study was carried out in two phases: first, with the participation of two collaborators, the guided tour tool was used to record information about medicinal climbing plants and collect botanical specimens. In the next phase, the checklist-interview technique was used with ten new participants who contributed to expand and verify the data obtained previously. To assess the versatility of use of the identified medicinal species, the relative importance index (RI) was calculated. To determine the main therapeutic indication, the fidelity level (FL) was calculated. Fifty-one climbing plant species were identified, belonging to 42 genera and 23 families, of which the most representative were Bignoniaceae (10 spp.), Apocynaceae (5 spp.), Passifloraceae (4 spp.), Convolvulaceae, Cucurbitaceae and Fabaceae (3 spp. each). There was a predominance of woody medicinal vines (51%). Voluble was the most frequent climbing mechanism (67%). Most of the plants are both spontaneous and cultivated (51%) and are found in six environments. The main indication of the plants was for the treatment of diseases in the general/nonspecific health category (22.58%). The leaves were frequently used (30.67%), preparation was mainly through tea (41.18%) and administration was mainly oral (39.33%). The species that showed the greatest versatility were Mascagnia sepium (A. Juss.) Griseb. (IR=2.00) and Pleonotoma sp. (IR=1.82). Adenocalymma flaviflorum (Miq.) L.G. Lohmann, Fridericia sp., Distimake macrocalyx (Ruiz & Pav.) A.R. Simões & Staples and Phaseolus lunatus L. had high levels of fidelity (100%). Documenting indigenous knowledge about climbing plants is essential to strengthen the resilience of communities, ensuring their continuity and preservation for future generations. This study highlights the relevance of protecting both biodiversity and ancestral knowledge, ensuring that these traditional practices continue to promote sustainability and preserve the cultural identity of indigenous populations.
