Although studies have demonstrated the effectiveness of the application of biostimulants to seeds, some results are contradictory. Therefore, more research is needed to verify the suitability of the methods used and the timing of the application of these products. Cucurbits are important in the agribusiness of Brazil. In addition to their economic and food value, the cultivation of cucurbits generates direct and indirect jobs, since it demands labor throughout the production chain. Because of this, this study aimed to evaluate the effect of the application of the biostimulant Stimulate® in the initial development of Luffa operculata (L.) Cogniaux seedlings. For imbibition, the following treatments were adopted: 0.0 (control); 1.0; 2.0; 3.0 and 4.0 mL of Stimulate®/L of distilled water. The variables analyzed were: first germination count, germination speed index, germination, mean germination time, germination uncertainty, number of leaves and seedling length. To this end, a completely randomized design was used, with four replicates of 25 seeds per treatment. The resulting data were submitted to variance analysis; following that, regression was applied, since treatment is a quantitative factor. Doses of the biostimulant between 1.77 and 3 mL.L-1 can be recommended for L. operculata seeds, as they promoted improvements in all analyzed variables.
