A falta de conhecimento e os desafios ecológicos na reprodução de graminóides do Cerrado têm impedido a produção comercial de mudas, dificultando os esforços para restaurar o Cerrado. Este estudo teve como objetivo avaliar a sobrevivência de perfilhos vegetativos provenientes da propagação clonal de cinco espécies nativas de graminóides cespitosos do Cerrado. Coletamos dez plantas adultas (matrizes) por espécie, em uma área de cerrado sensu stricto, em São Carlos – SP, para serem utilizadas como fonte de unidades clonais (perfilhos). Um total de 68 perfilhos por espécie foram separados e transplantados para tubetes, com a sobrevivência dos perfilhos sendo monitorada em condições de viveiro por 60 dias. Axonopus pellitus, Bulbostylis hirtella e Aristida jubata apresentaram taxas de sobrevivência próximas a 70%, enquanto Aristida setifolia e Andropogon bicornis tiveram taxas de sobrevivência abaixo de 12%. Esses resultados sugerem que o transplante de perfilhos pode ser um método viável para a produção comercial de parte das espécies graminóides do Cerrado, contribuindo para restauração desse bioma.
