Moringa (Moringa oleifera Lam.) is an exotic species, from the Indian Northeast, the Moringaceae family and has significant economic importance, with many applications in industry and medi-cine. This species spreads mainly by seed, so obtaining information on the behavior of different temperature and substrate on germination becomes essential since there is no standardized methodology for installation of the germination test. Therefore, this study aimed at evaluating the influence of substrate and temperature on germination and vigor of Moringa oleifera Lam. seeds. The experiment was conducted at the Seed Analysis Laboratory of the Federal Rural University of the Semi-Arid (UFERSA). The statistical design was completely randomized in a 5x2 factorial scheme (temperature x substrate), totaling ten treatments with four replicates of 25 seeds. The substrates were tested roll paper and vermiculite. Then the seeds were incubated at room Bio-chemical Oxygen Demand (B.O.D.) at constant temperatures of 20, 25, 30 and 35 °C and 20-30 °C alternating with a photoperiod of 8 hours. We evaluated the percentage, the average time and the germination speed index and the shoot length and root and total dry weight of seedlings. The roll paper substrate at temperatures of 25 to 30 °C, as well as vermiculite of 30 °C temperature are the most suitable combinations to evaluate germination and vigor of seeds of Moringa oleifera Lam.
