In this work the objective to evaluate the effect of different concentrations and application forms of the mixture of plant regulators listed in Stimulate® on germination and seedling production of watermelon cv. Crimson Sweet. The first experiment was conducted in a greenhouse type BOD, evaluating the germination and vigor depending on the dosages of Stimulate® (0; 2.5; 5.0; 7.5 and 10 mL kg-1 ) applied on seeds. The second experiment was conducted in a greenhouse, where the treatments applied were the same used in the first experiment, by establishing the emergence and seedling development. In the third experiment, the seedlings were sprayed with Stimulate® in doses: 0; 0.25; 0.5; 0.75 and 1%, by evaluating the length of the shoot and root, number of leaves and root dry mass and the shoot. In the three experiments was used completely randomized experimental design with 5 treatments and 5 repetitions. The application of mixture of plant regulators listed in Stimulate® in concentrations of 5 ml kg-1 favored the percentage of normal seedlings on watermelon cv. Crimson Sweet. The percentage of emergence and seedling development of watermelon had no influence with the application of Stimulate® on seeds. Foliar application of Stimulate® at a concentration of 0.5% promoted larger seedlings with neck diameters; however this form of application should be better studied in virtue of some traits analyzed were influenced negatively, as the root length.
