Planta que anda? Conheça a palmeira da Amazônia que parece se mover pela floresta
Paxiúba Brendon Campos/Instituto Inhotim Na Amazônia, uma palmeira apoiada sobre raízes que lembram pernas gigantes desperta curiosidade por supostamente se deslocar entre as árvores. Mas a planta anda mesmo? Segundo a doutora em Botânica e professora da Universidade Federal de Rondônia (Unir), Osvanda Silva de Moura, tudo não passa de ilusão. "É um processo natural de substituição das raízes de apoio. Novas raízes crescem e as antigas se decompõem, gerando uma falsa sensação
A palm tree native to the Amazon, known as paxiúba, has gained notoriety for its unique root system that resembles giant legs, leading to the popular belief that it can walk. However, botanists explain this phenomenon is an optical illusion caused by the natural process of root replacement. As new support roots grow and old ones decay, the tree appears to shift its position over time, though its trunk remains stationary.
These distinctive "stilt roots," which can grow up to two meters tall, are crucial for the paxiúba's survival in swampy, unstable environments. They provide essential stability, aid in gas exchange in low-oxygen soils, and help the plant reach sunlight. Beyond its ecological role, the paxiúba is a vital food source for various Amazonian fauna and its materials are utilized by local communities for construction and crafts.
The paxiúba palm's unique root structure and its ecological and cultural significance highlight the fascinating adaptations of Amazonian flora and its integral role in the rainforest ecosystem.
