Description
Summary:The unusual development of branches along the stem of Euterpe edulis is described for the first time. Branches originated at 2 to 190 cm from the ground. Ramified individuals and branches were able to produce reproductive structures and some branches produced roots. A plausible cause for the observed anomaly could be genetic problems due to small population sizes. The better agreement of this process can have a positive effect in the harvest of the heart of palm through the artificial induction of sprouts, what would prevent the death of the individual. O desenvolvimento anormal de ramos ao longo do estipe de Euterpe edulis é descrito pela primeira vez. Os ramos se originaram a uma altura que variou de 2 a 190 cm do solo. Indivíduos ramificados e ramos foram capazes de produzir estruturas reprodutivas e alguns ramos produziram raízes. Uma possível causa para a anomalia observada seriam problemas genéticos decorrentes dos pequenos tamanhos populacionais. Um melhor entendimento desse processo pode ter um efeito positivo na extração do palmito dessa espécie através da indução artificial de brotos, evitando assim a morte do indivíduo.
