Seed development may be divided up into embryonic morphogenesis and seed maturation, while diverse genes were connected disconnected in order to bring about such processes. Features as desiccation tolerance, dormancy germination capacity are acquired throughout regulated by the presence interaction of phytohormones abscisic acid (ABA), gibberellin (GA) ethylene. The purpose this study was analyze expression with ABA, GA ethylene biosynthesis during lettuce seeds. For that reason, the LsNCED, LsGAox and ACO-B genes evaluated means real time polymerase chain reaction (PCR) technique seeds from seven cultivars harvested at maturation stages 5, 10, 15 20 days after anthesis. It concluded the LsNCED gene related imposition final development; the LsGA3ox gene occurred initial theACO-B was greater (5 DAA) late (20 development, inducing germination. profile LsGA3oxand ACO-B genes dependent on cultivar.

Key words: Phytohormones, (PCR).
