Sumario:The effect of applications of low concentrations of salicylic acid (SA) on the number of flowers and the date of flower initiation in Petunia (Petunia híbrida) in reported in this paper. Concentrations of 1 μM to lpM of SA were spread on three occasions to the shoot of plantlets cultivated in greenhouse conditions. Analysis of the results showed that all the concentrations of SA tested increased the number of open flowers per plant. Concentrations as low as lpM or 0.lnM induced positive riesponses by 33 % and 37 %, as compared with that of the control. The highest concentration of 1 μM increased not only the number of flowers by 72 % but also induced early flowering by six days.
