Resumo: Tillering dynamics during regrowth in the spring (September to December 2009) on signal grass (Brachiaria decumbens cv. Basilisk) pastures deferred in the beginning of April 2009 is evaluated. Four pasture heights were evaluated at the beginning of deferment (10, 20, 30 and 40 cm). The experimental design consisted of completely randomized blocks with two replications. Rise in pasture height at the beginning of deferment decreased the appearance rate, increased the mortality rate and reduced the survival rate, the balance between appearance and mortality and the stability index of the tiller population at the beginning of the spring. Pastures deferred at initial height of 30 and 40 cm presented relatively stable tiller appearance rate between the beginning and end of spring. However, these pastures presented greater mortality rate, lower survival rate, lower balance between appearance and mortality and lower stability index of the tiller population at the beginning of spring when compared to rates at the end of spring. Pastures managed with shorter initial heights (10 and 20 cm) provided more tissue renewal in the subsequent growth season after their utilization in the winter._________________________________________________________________________________________ RESUMO: O trabalho foi realizado para avaliar a dinâmica do perfilhamento durante a rebrotação na primavera (setembro a dezembro de 2009) em pastos de capim-braquiária (Brachiaria decumbens cv. Basilisk) diferidos no início de abril de 2009. Foram avaliadas quatro alturas do pasto no início do diferimento (10, 20, 30 e 40 cm). O delineamento experimental utilizado foi o de blocos completos casualizados com duas repetições. A elevação na altura do pasto no início do diferimento diminuiu a taxa de aparecimento, aumentou a taxa de mortalidade e reduziu a taxa de sobrevivência, o balanço entre aparecimento e mortalidade e o índice de estabilidade da população de perfilhos no início da primavera. Pastos diferidos com altura inicial de 30 e 40 cm apresentaram taxa de aparecimento de perfilhos relativamente estáveis entre o início e final da primavera. Contudo, esses pastos apresentaram maior taxa de mortalidade, menor taxa de sobrevivência, menor balanço entre aparecimento e mortalidade e menor índice de estabilidade da população de perfilhos no início da primavera em relação ao final da primavera. Pastos manejados com menor altura inicial (10 e 20 cm) apresentam maior renovação de tecidos na estação de crescimento subsequente após utilização dos mesmos no inverno.
