The use of plant regulators in agriculture is a reality. This work aimed at studying the action of trinexapac-ethyl in the germination process of endive varieties. The experimental design was completely randomized in a 3x4 factorial scheme using three cultivars of Endive: Endive cv. Radiche (ER); Cv. Sugar Loaf (ESL) and cv. Catalan (EC); with four doses of trinexapac-ethyl: Zero ml L-1 (control); 0.033 ml L-1; 0.066 ml L-1, and 0.133 m L-1, and four replicates. After 15 days were evaluated: Germination Speed Index (GSI); Speed of Germination (SG); Percentage of Normal Plants (%NP); Percentage of Abnormal Plants (%AP); Number of Leaves (NL); Total Leaf Area (TLA); Average Root Length (ARL); Average Length of Aerial Part (ALAP); Dry Root Mass (DRM); Dry Shoot Mass (DSM). The use of trinexapac-ethyl did not benefit the germination process of the endive cultivars. Trinexapac-ethyl caused a lower initial development in endive cultivars from the 0.033 ml L-1 dose.
