Abstract: 
  • Este trabalho teve por finalidade estudar o efeito de reguladores vegetais sobre a emergência e desenvolvimento inicial de gemas de cana-de-açúcar 'IAC 52-150', submetidas ao tratamento térmico por via úmida. Para tanto, as gemas foram tratadas durante uma hora em soluções de ácido indolilacético (IAA) e ácido naftalenacêtico (NAA), nas concentrações de 10, 25, 50 e 100 ppm, em ácido indolbutírico (IBA) nas concentrações de 10 e 25 ppm e em água pura (testemunha). Imediatamente após o tratamento, as gemas foram plantadas em germinadores de areia. IBA 10 ppm tendeu a favorecer a emergência e o enraizamento das gemas. IAA não afetou a emergência, enraizamento e peso da parte aérea da cana-de-açúcar. Aplicação de NAA 100 ppm reduziu a porcentagem de emergência e o peso da parte aérea do cultivar IAC 52-150.
  • The effect of growth regulators on the germination and initial development of sugar cane shoots submitted to high temperature treatment by the moist method was studied. The shoots were treated during 1 hour with indoleacetic´acid (IAA) and naphthaleneacetic acid (NAA) at the concentrations of 10, 25, 50 and 100 ppm, with indolebutyric acid (IBA) at the concentrations of 10 and 25 ppm and with pure water (control). Immediately after the treatment, the shoots were planted in sand germinators. The results showed that treatment with IBA 10 ppm promote a tendency to induce germination and roots development. The root system development was not affected by other treatments, but the development of the aerial portion was adversely affected by NAA 100 ppm. The results showed that, after 60 days, the number of emerged shoots was significantly lower than that of the control in the plots treated with 100 ppm of NAA.
